Proper 120^ phase shift between output leads stays constant over the entire frequency

range. Typical motor voltage and current at 60 hertz (full load) is shown on Figure 3*6.

Note that although the voltage is in pulses, the current waveform is near sinusoidal.

Voltage s leading current, typical in induction motors.
