What Factors May Influence the Rotation of an Electric Motor?

[DeCarson]

Motor rotation may be related to electric current, as the amount of current directly affects the rotation of an automotive electric motor. All vehicles are equipped with electric motors, specifically the starter motor, which converts the electrical energy from the battery into mechanical energy to drive the engine flywheel rotation, thereby initiating engine startup. The strength of the current directly impacts the operational efficiency of the motor. An electric motor generates a rotating magnetic field through energized coils (i.e., stator windings) and acts on the rotor (such as a squirrel-cage closed aluminum frame) to create magnetoelectric torque for rotation. The motor primarily consists of a stator and rotor, with the direction of force exerted on the energized conductor in the magnetic field being determined by both the current direction and the magnetic field lines (direction of the magnetic field).
