Woodworking and stationary power tool AC motors power metalworking and woodworking equipment. They can be split-phase or capacitor-start where the split-phase motors are single-phase with a moderate starting torque. Capacitor-start motors are single-phase and use a capacitor to provide additional power during startup for higher torque than split-phase motors. All models are commonly used with lathes, planers, table saws, sanders, and grinders.
