please help i am doing an assignment on electrictric motors and have no clue what this answer is.. the question isExplain where the force comes from that makes the elecrtic motor work!!!! somebody?
Yep, what Justin said.....
In a DC motor power is fed usually to the internal shaft with brushes, there are two or more magnets on oposite sides of the caseing. the power goes through a winding or coil that creates a magnetic field. pushing the coil away from one magnet and towards anouther with the opposit charge. As it spins the brush looses contact with a contact plate and then makes contact with anouther contact plate for a different winding, and the process happens again, as the shaft turns different windings are energised keeping the rotation going. In an AC motor works about the same however an AC motor makes use of the alternating direction of current to create and colapse magnetic fields that push then pull the rotor around. SO in answer, it works of magnetism, specifically electromagnets.
