With single-phase power, all of a motor’s coils begin their cycle at the same time. The magnetic field doesn’t rotate, so the rotor can’t move. Engineers worked around this by using a separate starter coil in series with a capacitor.

Some motors have a run capacitor in addition to the start capacitor because the two states have different requirements, especially for larger electric motors. A start capacitor loads the motor slightly after it comes up to speed. This reduces the motor’s peak efficiency because the capacitor uses some of the electric power.
