Induction Motor
Induction motor From Wikipedia, the free encyclopedia Jump to navigation Jump to search "Tesla motor" redirects here. For the electric car company, see Tesla, Inc. Three-phase totally-enclosed fan-cooled ( TEFC ) induction motor with end cover on the left, and without end cover to show cooling fan on the right. In TEFC motors, interior heat losses are dissipated indirectly through enclosure fins, mostly by forced air convection. Cutaway view through stator of TEFC induction motor, showing rotor with internal air circulation vanes. Many such motors have a symmetric armature, and the frame may be reversed to place the electrical connection box (not shown) on the opposite side. An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic fi...
