WebSet the ceiling fan at the slowest speed that the motor can rotate. This will be needed when paired with the heating system. Replace the wall box and plate to its position in the wall when the speed is where you want it to be for minimum and maximum levels. A dimmer can't control a lot of fixtures, or it will overload its maximum wattage. WebMay 6, 2024 · If you are trying to use slow speed a DC motor is a poor choice without a gearbox to slow things down. The motor has little torque because you are effectively running the motor on low voltage. PWM with a 50% duty cycle is going to behave similar to the motor on 50-60% voltage.

WebApr 11, 2024 · 5v * (100% / 100) = 5 volts. A duty cycle of 20% produces the equivalent voltage: 5v * (20% / 100) = 1.0 volts. As the PWM duty cycle changes, the motor reacts to the equivalent voltage and spins the motor at a speed that is proportional to that value. A lower duty cycle slows the motor; a higher duty cycle increases motor speed.
