Troubleshooting Motor Control Circuits — Part 2. Isolating problems in the control circuit March 19, 2015. 9 min read . In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit ...

Integrate the motor to a machine, based on analysis of motor equations for voltage, current, torque and speed. Implement the motor and accompanying rotary sensor into a motor control circuit in both ...

E-2's main propulsion system consists of two DC motors directly driving contra-rotating propellers. An underwater vehicle with a single propeller is subject to undesirable torque forces, especially if ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...
