The back EMF, along with the RL circuit in a brushed DC motor, brings non-linearity to the PWM control and the PWM frequency and PWM duty cycle become significant for getting the best output power.

Now’s a good time to try something new by driving a couple of DC motors ... is generated when a spinning motor is shut off and you’re going to need a control system that can handle these ...

The bearings aren’t complete crap, but the spindle of these CNC machines is a standalone PWM controller with ... [SUF] is building a DC motor controller for a Chinese spindle motor that doesn ...

Maxon Precision Motor's ESCON 50/5 OEM module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can efficiently control permanent magnet brushed DC motors (PMDC motors) and ...

The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package. The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package.

Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) ...
