Determine neutral wire on induction motor
WebSep 24, 2014 · As a single phase induction motor it will have at least two windings. They may share a common wire to neutral or each have it's own neutral connection. One of those windings will be connected to active directly, the other winding will be connected to active through the capacitor which provides the necessary phase shift to decide direction.

The voltages measured are the true phase to neutral voltages. The phase to phase voltages can be accurately calculated from the phase to neutral voltages’ amplitude and phase using vector mathematics.
WebThe purpose of the capacitor is to create a poly-phase power supply from a single-phase power supply. With a poly-phase supply, the motor is able to: 1. Set the rotation direction. 2. Provide starting torque for the motor and increase torque during operation. Oriental Motor's AC motors are all permanent-split capacitor type (capacitor start and ...
