Where are the windings on a capacitor start motor?
The figure below shows the connection diagram of a Capacitor Start Motor. The capacitor start motor has a cage rotor and has two windings on the stator. They are known as the main winding and the auxiliary or the starting winding. The two windings are placed 90 degrees apart. A capacitor C S is connected in series with the starting winding.
What should I do when I remove the starter motor?
If you removed the starter motor for inspection, this is a good chance to check the flywheel as well. The flywheel is the large, heavy wheel between the engine and transmission. This is the wheel that the starter pinion gear engages to crank the engine. Once you’ve removed the starter motor, set your transmission to Neutral.
Is the Delta contactor open or closed on a star starter?
The Main contractor is closed and the Delta and Star contactors are open. There is voltage on one end of the motor windings, but the other end is open so no current can flow. The motor has a spinning rotor and behaves like a generator. Delta State: The Main and the Delta contactors are closed. The Star contactor is open.

Do you use a motor starter or just a disconnect?
Single motors under 5hp that are used occasionally, manually started we may use a fused disconnect. Frequent starts, 480V, and larger hp we use starters because they will last longer and IMO are safer. (B) allows cord cap and receptacle as the controller 1/3 Hp or less.
