Single-phase motors are common in many industries and can be found in ... To safely discharge a capacitor, place a 20,000-ohm, 2W resistor across the terminals for 5 sec. After you discharge the ...

Another means of shortening stepmotor steps is the 5-phase method, which adds a pole pair to the stator of a regular 2-phase hybrid step motor. This changes the rotor-stator offset of a 2- phase ...
