Power PROFET PWM motor driver. This power driver circuit is based on the PROFET transistor BTS 555 and is working at a switch frequency of 500 Hz. The reason for this low switch frequency is that the BTS 555 is a relatively slow component. This was the authors fist experimental PWM setup. However the power MOSFET version (below) is better.

The circuits for two-wire stepping are as follows: Unipolar stepper two-wire circuit: Biolar stepper two-wire circuit: Programming the Microcontroller to Control a Stepper. Because both unipolar and bipolar stepper motors are controlled by the same stepping sequence, we can use the same microcontroller code to control either one.

A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical faults.

Smart Motor Control Make Smart and Informed Decisions with Smart, Intelligent Devices. Efficient motors drive performance and the impact of motor failure can be significant. With intelligent motor control devices, you can improve productivity and help avoid motor failures with an integrated, data-driven approach.

The auxiliary contact is often used in a relay logic circuit, or for some other part of the motor control scheme, typically switching 120 Volt AC power instead of the motor voltage. One contactor may have several auxiliary contacts, either normally-open or normally-closed if required.

Jul 13, 2019· When you take a new motor starter out of the box the manufacturer typically pre-wires the OL contact so that you do not have to. Whether or not the OL contact breaks the grounded side of the circuit depends on other factors. For instance if it was a 480 V control circuit it would open the other ungrounded leg of the control circuit.

the electrical circuits shown, wired in parallel to each other, and a corresponding multi-pole permanent mag-netic rotor. For two circuits there are two electrical rev-olutions per mechanical revolution, so for a two-circuit motor, each electrical commutation phase would cover 30 degrees of mechanical rotation.
