Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

The driver is a key factor in determining a motor’s stall performance. Temperature can affect the stall torque of brushless DC motors. Tolerances on the motor parameters can significantly impact the ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

All the motors produce either interaction torque, reluctance torque or a combination of both. The second article in this series discussed the underlying principles common to all motors. As we have ...

Electrical equipment often has at least one motor used to rotate or displace an object from its initial position. There are a variety of motor types available in the market, including induction motors ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

High performance compound dc motor developed by Astrosyn A high performance dc motor for use in demanding environments has been developed by Astrosyn International Technology. The APW166 compound ...
