Performance Analysis of Motor Stator Stator StructureNegotiableMOQ: 1 Piece
Motor rotor: also the rotating parts of the motor. The motor consists of a rotor and a stator, which is used to implement electrical and mechanical energy and mechanical energy and electrical energy conversion device. The motor rotor is divided into motor rotor and generator rotor.
Motor rotor is divided into two kinds of internal rotor rotation and external rotor rotation. The inner rotor rotates in the middle of the motor as the rotating body, the output torque (referring to the motor) or the income energy (referring to the generator). External rotor rotation mode that is the motor body for the rotating body, a variety of ways to facilitate the application of various occasions.
Brushless DC motor rotor by a very pole number of permanent magnets embedded in the core surface or embedded within the core structure. Permanent magnets used NdFeB and other high coercivity, high residual magnetic induction density of rare earth permanent magnetic materials produced. The effect of the permanent magnet of the rotor is similar to that of the permanent magnet used in the brush motor, and a sufficient magnetic field is established in the air gap of the motor. The difference is that the permanent magnet in the brushless DC motor is mounted on the rotor Above, while the brush motor magnet mounted on the stator above. Brushless DC motor rotor structure using multi-surface paste magnetic pole, also known as tile-shaped magnetic pole. Surface paste magnetic pole that is, the outer surface of the core paste the magnetic field of magnetic rare earth permanent magnet, reasonable design can be obtained in the form of square wave air gap magnetic flux density.
Motor rotor processing technology
Place the metal inserts in the mold and inject the BMC plastic. Heated to 160 degrees.
The power of the motor. Should be based on the power required to produce machinery to choose, try to make the motor running under the rated load. Selection should pay attention to the following two points:
(1) If the motor power is chosen too small, there will be a "small horses cart" phenomenon, resulting in long-term motor overload. Insulation due to heat damage. Even the motor was burned.
(2) If the motor power is selected too large. There will be "big horse car" phenomenon. Its output power can not be fully utilized, power factor and efficiency are not high (see table), not only for users and the grid disadvantage. But also cause energy waste.
