WebMar 26, 2024 · V = KEώ + iR + L (di/dt) A PWM driver will increase the voltage applied to the stepper motor to keep the current and torque constant. At some speed, the power supply will not have enough voltage, and the motor current will begin to fall. The torque drops with the current. If using a higher voltage power supply, the dynamic torque remains flat ... WebJun 1, 2004 · PWM — the unconventional way to regulate pressure. June 1, 2004. Pulse width modulation (PWM) has been used successfully in electronic control circuits for at least forty years. It is an efficient method for controlling a large amount of output power while expending a relatively small amount of power in the controller.
