Mar 19, 2008· A 1horsepower electric motor uses electrical energy at the rate of almost 750 watts, so it will need a minimum of about 7 amps of current on a 120volt circuit. Electric motors need additional current as they startup, or if they stall, requiring up to 200% of the nameplate current rating. Therefore, the motor would need 14 amps.

Construction and Principle of Operation of the Shunt DC Motor
The DC Shuntwound motor, running on Direct current, has its field windings placed in parallel to the armature. In Electrical terms, parallel is generally denoted as shunt. That is the reason behind naming it a DC Shunt motor. Same voltage is applied to both shunt winding and armature in this motor. This parallel configuration allows independent path of current for field winding and armature.
