Do they both need starter capacitor or no ? What about a capacitor run ?

    All split phase motors are single phase.

    Split phase means: two sets of stator windings (start and run).

    Permanent split phase supplies the start winding at all times

    through a small capacitor.

    Split phase energizes start windings instantaneously while starting

    with a start device (Voltage relay, current relay, PTC, or other);

    and might or might not use a start cap to improve starting torque.
