DC Brushless Motor - Housing
The basic definition for Brushless DC Motors are an automatic device that uses an error-correction routine to correct the motion of the Brushless DC Motors. The general term Brushless can be applied to systems other than a Brushless DC Motors that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term Brushless is used it applies to a 'Brushless DC Motors' but this term is also used as a general control term with the meaning of a feedback loop to position whatever the item is including a Brushless DC Motors.
A Brushless DC Motors are different from other controlled motors in that they are controlled by a time-based derivative commonly referred to as the PID loop. A Brushless DC Motors are used to control position must be capable of changing the velocity of the output shaft because the time-based derivative, or the rate of change of position, is velocity.
A Brushless DC Motors are used in a variety of applications in many different industries. Some of the applications are Appliances, Automotive, Aerospace, CNC, Consumer, Instrumentation, Medical, Packaging Equipment, and Semiconductor.
The stator of Brushless DC Motors consists of stacked steel laminations the windings are placed in the slots that are cut inside the laminations. The stator of a Brushless DC Motors is similar to an AC motor however the windings are different. A Brushless DC Motors have three stator windings connected in either a star or Delta configuration. Each of these windings are constructed from multiple coils connected together to form a winding. Anaheim Automation typically have six coils per Brushless DC Motors which are made into a three-phase winding. There is usually an even number of polls
There are mainly two types of stator windings trapezoidal and sinusoidal. The difference is made on the basis of the interconnection of the coils of the stator windings which results in a different type of back EMF the trapezoidal variant gives its back EMF in the shape of a trapezoid. The sinusoidal variation gives its Brushless DC Motors a back EMF in the sinusoidal fashion going along with the current the faulted also has the shape of a trapezoid and a sinusoid. The differences between the two Brushless DC Motors are the sinusoidal Brushless DC Motors have smoother output torque than that of a trapezoidal Brushless DC Motors. The stator will winding can be wound for multiple folk voltages. This can be customized for almost any particular applications are speed and torque requirements.
The rotor is made up of permanent magnets in typically have between two and eight poles the magnets are bonded onto the rotor core in alternating north and south pole fields. Ferrite magnets are normally used to make the permanent magnet rotor. For higher power density applications rare earth magnets are being used more frequently the ferrite magnets are less expensive but have lower flux density when compared to the rare earth magnets. The cost of rare earth magnets is also coming down. Higher power density means that Brushless DC Motors can put out more torque in a smaller volume which is advantageous to manufacturers that are continuously pushed provide smaller and smaller packages.
Rare earth magnet types:
Samarium Cobalt (SmCo)
The alloy of Neodymium, Ferrite, and Boron (NdFeB)
Anaheim Automation provides many different accessories for our Brushless DC Motors. These accessories include a brake, encoder, connector, cable and a driver.
The Brushless DC Motors brakes have a 24vdc system. These Brushless DC Motors brakes are perfect for any holding applications. They are available on any Anaheim Automation Brushless DC Motors, and are already attached to the rear of the Brushless DC Motors. The Brushless DC Motors brakes have a low voltage design for applications that are susceptible to weak batter, brown out, or long wiring runs. When electric power is applied to the Brushless DC Motors brake the armature is pulled by the electromagnet force in the magnet body assembly, which overcomes the spring action. This allows the friction disc to rotate freely. When electrical power is interrupted, the electromagnetic force is removed and the pressure spring mechanically forces the armature plate to clamp the friction disc between itself and the pressure plate.
Brushless DC Motors cables can be made with the supplied Brushless DC Motors connector, or can be purchased from Anaheim Automation.
Many Brushless DC Motors types today are being made with the housing less design. In this design the laminations are exposed and are coated with a paint to prevent the laminations from rusting. Some Brushless DC Motors types are still housed in an extrusion or aluminum or steel cylindrical housing and the laminations of the stator are placed and secured in that housing.
The feedback for Brushless DC Motors are done by the use of Hall sensors when rotating the Brushless DC Motors in the stator windings need to be energized sequentially. The controller needs to know the rotor position in order to understand the next winding to be energized following the correct energizing sequence. The rotor position is sensed by the Hall sensors embedded in the back end cap of the Brushless DC Motors housing. The Brushless DC Motors utilizes three Hall sensors. They are separated by either 60° or 120°. The Hall sensors sense either the rotor magnet or an external magnet placed on the back and shaft. They give a digital signal signifying whether or not a north or South Pole has passed the censors using the signals from these sensors the Brushless DC Motors controller can easily maintain the Brushless DC Motors velocity. The Hall sensors are normally mounted on a PC board and fixed to the back end cap on the non-driving end of the Brushless DC Motors
For low-speed applications it is recommended to use an encoder for the feedback rather than the Hall sensors. The Hall sensor counts per revolution can only be as great as a number of polls times the number of Hall Sensors. The Brushless DC Motors controller can use this higher count to its advantage when operating the Brushless DC Motors. With more counts per revolution at its disposal, the Brushless DC Motors controller can use this additional information to more precisely control the velocity of the Brushless DC Motors. The higher the resolution on the encoder to more finely the Brushless DC Motors controller can control the Brushless DC Motors. Even though the expense is much greater for encoders when compared to Hall sensors this price can be justified as it can result in very precise control for a much lower cost than alternative technologies such as Servo motors were AC motors or synchronous motors.
The following environmental and safety considerations must be observed during all phases of operation, service and repair of a Brushless DC Motors system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the Brushless DC Motors and controller. Please note that even a well-built Brushless DC Motors products operated and installed improperly, can be hazardous. Precaution must be observed by the user with respect to the load and operating environment. The customer is ultimately responsible for the proper selection, installation, and operation of the Brushless DC Motors system.
The atmosphere in which a Brushless DC Motors are used must be conducive to good general practices of electrical/electronic equipment. Do not operate the Brushless DC Motors in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, the Brushless DC Motors and controller must be protected from the elements by an adequate cover, while still providing adequate air flow and cooling. Moisture may cause an electrical shock hazard and/or induce system breakdown. Due consideration should be given to the avoidance of liquids and vapors of any kind. Contact the factory should your application require specific IP ratings. It is wise to install the Brushless DC Motors and controller in an environment which is free from condensation, electrical noise, vibration and shock.
Additionally, it is preferable to work with the Brushless DC Motors and controller system in a non-static protective environment. Exposed circuitry should always be properly guarded and/or enclosed to prevent unauthorized human contact with live circuitry. No work should be performed while power is applied. Don't plug in or unplug the connectors when power is ON. Wait for at least 5 minutes before doing inspection work on the Brushless DC Motors system after turning power OFF, because even after the power is turned off, there will still be some electrical energy remaining in the capacitors of the internal circuit of the Brushless DC Motors controller.
Plan the installation of the Brushless DC Motors and controller in a system design that is free from debris, such as metal debris from cutting, drilling, tapping, and welding, or any other foreign material that could come in contact with circuitry. Failure to prevent debris from entering the Brushless DC Motors system can result in damage and/or shock.
The following information is intended as a general guideline for wiring of the Anaheim Automation Brushless DC Motors product line. Be aware that when you route power and signal wiring on a machine or system, radiated noise from the nearby relays, transformers, and other electronic devices can be inducted into the Brushless DC Motors and encoder signals, input/output communications, and other sensitive low voltage signals. This can cause systems faults and communication errors.
WARNING - Dangerous voltages capable of causing injury or death, may be present in the Brushless DC Motors system. Use extreme caution when handling, wiring, testing, and adjusting during installation, set-up, tuning, and operation. Don't make extreme adjustments or changes to the Brushless DC Motors system parameters, which can cause mechanical vibration and result in failure and/or loss. Once the Brushless DC Motors are wired, do not run the Brushless DC Motors controllers by switching On/Off the power supply directly. Frequent power On/Off switching will cause fast aging of the internal components, which will reduce the lifetime of Brushless DC Motors system.
Strictly comply with the following rules:
-Follow the Wiring Diagram with each Brushless DC Motors
- Route high-voltage power cables separately from low-voltage power cables.
-Segregate input power wiring and Brushless DC Motors power cables from control wiring and Brushless DC Motors feedback cables as they leave the Brushless DC Motors controller. Maintain this separation throughout the wire run.
-Use shielded cable for power wiring and provide a grounded 360 degree clamp termination to the enclosure wall. Allow room on the sub-panel for wire bends.
- Make all cable routes as short as possible.
NOTE: Factory made cables are recommended for use in our Brushless DC Motors and driver systems. These cables are purchased separately, and are designed to minimize EMI. These cables are recommended over customer-built cables to optimize system performance and to provide additional safety for the Brushless DC Motors system and the user.
WARNING - To avoid the possibility of electrical shock, perform all mounting and wiring of the Brushless DC Motors and controller system prior to applying power. Once power is applied, connection terminals may have voltage present.
The following information is intended as a general guideline for the installation and mounting of the Brushless DC Motors system. WARNING - Dangerous voltages capable of causing injury or death may be present in the Brushless DC Motors system. Use extreme caution when handling, testing, and adjusting during installation, set-up, and operation. It is very important that the wiring of the Brushless DC Motors and controllers be taken into consideration upon installation and mounting.
Subpanels installed inside the enclosure for mounting Brushless DC Motors system components, must be a flat, rigid surface that will be free from shock, vibration, moisture, oil, vapors, or dust. Remember that the Brushless DC Motors and controller will produce heat during work; therefore, heat dissipation should be considered in designing the system layout. Size the enclosure so as not to exceed the maximum ambient temperature rating. It is recommended that the Brushless DC Motors be mounted in position as to provide adequate airflow. The Brushless DC Motors should be mounted in a stable fashion, secured tightly. NOTE: There should be a minimum of 10mm between the Brushless DC Motors and any other devices mounted in the system/electric panel or cabinet.
NOTE: in order to comply with UL and CE requirements, the Brushless DC Motors system must be grounded in a grounded conducive enclosure offering protection as defined in standard EN 60529 (IEC 529) to IP55 such that they are not accessible to the operator or unskilled person. As with any moving part in a system, the Brushless DC Motors should be kept out of the reach of the operator. A NEMA 4X enclosure exceeds those requirements providing protection to IP66. To improve the bond between the power rail and the subpanel, construct your subpanel out of a zinc-plated (paint-free) steel. Additionally, it is strongly recommended that the Brushless DC Motors controller be protected against electrical noise interferences. Noise from signal wires can cause mechanical vibration and malfunctions.
