1. How does PWM control speed of DC motor?
- Pulse width modulation speed control works by driving the motor with a series of “ON-OFF” pulses and varying the duty cycle, the fraction of time that the output voltage is “ON” compared to when it is “OFF”, of the pulses while keeping the frequency constant.
2. What causes a DC motor to fail?
- High humidity levels can cause corrosion within the bearing, which leads to an increase in friction, which leads to an increase in wear. This could damage the shaft and bearings, preventing the motor from rotating smoothly, and affecting speed and torque.
3. How does PWM affect motor speed?
- The motor will run at a speed halfway between zero and full speed if we switch the power on and off quickly enough. A PWM controller does exactly that it turns on the motor in a series of pulses. Pulse Width Modulation is used to control the motor speed by varying (modulating) the width of the pulses.
4. What is a PWM DC Motor Speed Controller?
- The DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%. The motor speed controller can provide a continuous current of 8A to your DC motor or other DC load. The circuit also includes a 10A fuse, with the reverse connection of power supply and control voltage over-voltage protection function.
