Supply Voltage

Question: What supply voltage do the driver need?

Answer: The driver for the PCBMotor is supplied with a 5V power supply, and the transformers in the driver circuit is stepping the voltage up from 5V to 100-200Vrms. The Vs supply for the transformer can be decreased down to approximately 3V to make the motor slow down. However, when the rotor is mounted on the stator a minimum drive voltage is required to overcome the static friction between the rotor and stator and start the motor turning.
