The CCM5D digital PWM dc motor speed controller with LED Display operates from 6V to 24V DC at up to 8A, switching at 16kHz frequency with a live 0-100% duty ratio LED display, housed in a measuring 78x42x25mm. This ccm5d motor controller uses pulse width modulation it rapidly switches the motor’s power supply on and off at 16kHz, and the ratio of on-time to total cycle time (the duty cycle shown on the LED display) determines the effective average voltage delivered to the motor, which directly controls its speed without wasting power as heat the way a variable resistor-based controller would.
The ccm5d controller with display’s 16kHz switching frequency is specifically chosen because it sits above the human hearing range, conventional PWM controllers running at lower frequencies (1-5kHz) produce an audible whine from the motor windings at low speeds, while this pwm dc motor speed controller’s 16kHz operation keeps the motor acoustically quiet across its full speed range, including at slow speeds where low-frequency PWM whine is most noticeable.
The 0-100% duty ratio display gives operators an exact numerical readout of current speed setting rather than estimating from a knob position. This pwm motor speed controller controls brushed DC motors only, it is not compatible with brushless DC (BLDC), stepper or AC motors, which each require dedicated controller types with different drive architectures. Available on StemVolt. This controller is well-suited for quiet variable speed motor drives and PWM controlled dc motor electronics projects.
