Briefly, the motor fixing part is called a stator, on which is mounted a pair of stationary main magnetic pole of the DC exciter; rotating portion called the armature core, also known as the rotor.
1 rotor
Motor two-part rotor and a stator composed of a motor rotor: is the rotating part of the motor of which is used to achieve electrical and mechanical energy and mechanical energy to electrical energy conversion device . Rotor is divided into a motor rotor and a generator rotor.
rotatably
rotor rotatably into the inner rotor and the outer rotor rotatably ways. A rotor rotatably within the motor core intermediate rotating body, the output torque (refer to a motor) or income energy (of the generator). An outer rotor rotatably i.e., the outer body member to rotate the motor, to facilitate a variety of applications in different ways.
stator winding type
The shape of the stator winding fitted wiring different coil winding, can be divided into two types of centralized and distributed.
1. Concentrated winding
applied to the salient pole concentrated winding stator, a coil is generally wound into a rectangular, shaped warp tapes dressing, and then by dipping drying treatment, the iron core is fitted in the convex magnetic poles. Usually commutator motor (direct current motor and a universal motor comprises a) a single-phase exciting coil and the main pole shaded pole protrusion of the motor winding pole concentrated winding are used. Concentrated winding coils generally each have a pole, but there is also the consequent poles (salient pole) form, as framed by a shaded pole motor is a motor coil poles formed.
2. Distributed windings
Distributed motor stator winding is not convex palm pole, each pole by one or several coils according to certain rules fitted wire coil consisting of groups of magnetic poles of different polarities are formed after power, it is also called salient pole. Depending on the form fitted arrangement of the wiring, concentrically distributed windings can be divided into two and stacked.
(1) concentric winding concentric winding is similar to but different sizes by several coil shape, is fitted according to the same center position as a rotary-shaped coil assembly. Concentric windings may constitute a biplane or triplane windings according to different wiring. Usually single-phase motor or a small power part and the stator windings of the three-phase asynchronous motor coil using a large span of this type.
(2) The lap coil winding stack is generally the same shape and size of the coils per slot are fitted with one or two coil sides, one by one above the other and evenly distributed on the outer end of the groove form. The lap coil is divided into single and double stacked laminated two. Embedding only one coil per slot side is laminated a single winding, or single-lap winding; every two fitted slots belong to different coil groups are divided coil sides placed on the tank, the lower layer, stacked double winding, or He said double-stacked winding. Depending fitted wiring changes, lap coils in turn derived crossbar concentric double and single cross hybrid type and other types.
It is generally larger power phase induction motor stator windings more double stacked; and small motors are single multiple stacked winding patterns derived, but rarely stacked single winding.
2. Brushless DC motor rotor
rotor brushless DC motor using a multi-pole surface mounting type, also known as shoe-shaped magnetic poles. I.e. stick-pole surface attached to the surface of the tile radially magnetized rare earth permanent magnets of the outer core, the rational design of gap magnetic flux density can be obtained in the form of a square wave.
rotor of the brushless DC motor of a certain number of pole pairs of permanent magnets embedded in the core surface or embedded within the iron core. Currently, multi NdFeB permanent magnet of high coercivity, high remanent flux density of the rare earth permanent magnet material produced. Of the permanent magnet this permanent magnet rotor and the brush motor acts similarly used, a sufficient magnetic field is established in the motor air gap, which is different from the brushless DC motor comprising a permanent magnet mounted on the rotor above, the brush motor mounted on the stator top magnet.
