Typical stepper-motor control circuits use either logic gates and flip-flops or shift registers to generate the proper sequences of binary codes that produce bidirectional stepper-motor movement. A ...

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 ...

In the interior permanent magnet synchronous motor (IPMSM) design for the traction motor of fuel cell electric vehicles (FCEVs), it is necessary to analyze the nonlinear characteristics including ...

A push button triggers the homing sequence, and an onboard RGB LED provides real-time feedback, flashing red when the StallGuard threshold is crossed and green when the motor reaches the centre.

For a symmetrical winding multi-phase brushless DC motor (BLDCM), this paper proposes a fault-tolerant control method to reduce torque ripple after an open-circuit fault occurs in the system. When a ...
