Background
The motor is an electromagnetic device for realizing electric energy conversion or transmission according to an electromagnetic induction law. The permanent magnet type DC motor is also composed of stator magnetic pole, rotor, electric brush, and shell, the stator magnetic pole is made of permanent magnet (permanent magnetic steel) including ferrite, alnico, neodymium iron boron, etc. The structure can be divided into a cylinder type, a tile type and the like. Most of the electric motors used in recorders are cylindrical magnets, and most of the electric motors used in electric tools and automotive electric appliances are special block magnets.
The rotor is generally formed by laminating silicon steel sheets, and the number of the grooves of the rotor is less than that of the rotor of the electromagnetic direct-current motor. The small-power motor used in the recorder is mostly 3 slots, and the higher grade is 5 slots or 7 slots. The enameled wire is wound between two slots of the rotor core (three slots are provided with three windings), and each joint is welded on the metal sheet of the commutator respectively. The brush is a conductive part for connecting a power supply and a rotor winding and has two performances of conductivity and wear resistance. The electric brush of the permanent magnet motor uses a single metal sheet or a metal graphite electric brush or an electrochemical graphite electric brush.
The permanent magnet synchronous motor provides excitation by the permanent magnet, so that the structure of the motor is simpler, the processing and assembling cost is reduced, a collecting ring and an electric brush which are easy to cause problems are omitted, and the running reliability of the motor is improved; and because excitation current is not needed, excitation loss is avoided, and the efficiency and the power density of the motor are improved. The permanent magnet synchronous motor is composed of a stator, a rotor, an end cover and the like. The stator is basically the same as a common induction motor, and a lamination structure is adopted to reduce iron loss during the operation of the motor. The rotor can be made into solid or laminated by lamination. The armature winding can adopt a concentrated whole-pitch winding, and can also adopt a distributed short-pitch winding and an unconventional winding.
Permanent-magnet machine when using, need use motor protector to protect permanent-magnet machine, however traditional motor protector can't assist the heat dissipation to the motor when using, and the motor produces a large amount of heats when using for a long time, if not dispel in time, can cause irreversible damage to the motor, and the motor can take place the shake simultaneously when using, and the motor of shake also causes the motor to fix not hard up easily, and then leads to the situation of motor loss damage.
