The stator is part of the motor stationary. The stator consists of stator core, stator windings and base. The main function of the stator is to produce a rotating magnetic field, and the main role of the rotor is in the rotating magnetic field by the magnetic field cutting and produce (output) current.

The composition of the motor stator

The stator is usually composed of iron core, coil, skeleton (some no), lead, pull spring and so on. Stator has two kinds of wiring, one is 4-wire, the rotor string connected between the two stator windings, one is 2-wire, two stator windings connected and then connected with the rotor string and then the rotor string Connection, (connect the 4-wire diagonal 2 leads together). Two different wiring methods, but can be common. There are two ways of wiring: one is the cord leads; one is to rely on the connector on the skeleton leads to the kind of winding to retain the skeleton.

Motor stator fault handling

Stator common faults include winding circuit, short circuit, grounding, pull spring and brush grip contact bad, pull spring blown, fixed stator bolts and so on.

In order to achieve the versatility of the stator, some of the repair staff on the same core model, the stacking change (with electric knife part), the winding turns are also integrated average, processing, so that the generality of the stator increased. Xiaobian proposal, in order to ensure adequate power output, should make the core dedicated as well. Only to ensure that the original machine stator stack to ensure the performance of the machine parameters.

Some saw aluminum machine stator has two sets of windings, one group is the excitation winding, the other group is the brake winding, its role is when the excitation winding power, immediately produce reverse torque, so that the blade immediately stop, Safety factor.
