Low-cost, 8-bit, single-chip microcontrollers are stingy when it comes to on-chip PWM (pulse-width-modulation) resources. The use of a PWM resource often forces a designer to sacrifice a ...
A motor-drive servo amplifier's output voltage has a fundamental frequency and amplitude that corresponds to the motor speed, torque, and number of motor poles. PWM amplifiers, by their nature, also ...
