A stator capable of preventing the displacement of insulators and securely positioning the insulators at given positions. A stator includes a stator core formed with slots; a coil wound around the stator core, the coil comprising a coil side and a coil end, the coil end arranged outside the slot; and insulators provided in the slots. Each insulator includes a coil side-insulation part arranged between wall surfaces of a slot and a first coil side and electrically insulating the wall surfaces from the first coil side; and a coil end-insulation part formed in one piece with the coil side-insulation part and arranged outside the first slot. The coil end-insulation part is arranged between a first coil end and a second coil end and electrically insulates the first coil end from the second coil end.

Insulator for insulating coils of a stator of electric motor

A motor which can reliably prevent varnish from ending up entering a terminal block. The motor is provided with a terminal block to which lead wires of coils are connected. The terminal block has a bottom wall, a plurality of side walls which face each other, a terminal part which is provided between adjoining side walls, and a dam wall which is arranged at a position closer to the coils than the terminal part and which is formed integrally with the bottom wall and side walls without clearance. The dam wall has a lead wire holding part for holding a lead wire.

Motor provided with terminal block

An induction motor has a rotation detector, a heat dissipating disc for dissipating heat generated from a rotor, and a cooling fan for forcibly cooling the heat dissipating disc with outside air. The heat dissipating disc is disposed between the rotation detector and the cooling fan.

Induction motor equipped with heat dissipating disc for dissipating rotor heat

A fan having a function for detecting a fault such as a breakage or a loss of a rotating part of the fan as well as reduction in the rotational speed of the fan, the function being not affected by an operating condition of the fan. The fan includes a stationary part, a rotating part rotatably attached to the stationary part, a first electric circuit arranged on the rotating part, a second electric circuit arranged on the stationary part, the second electric circuit being electromagnetically connected to the first circuit, and a fault detecting circuit electrically connected to the second electric circuit, for detecting a fault of the rotating part.
