Automotive motor magnetic tile has low working efficiency and small temperature coefficient
Jul 13, 2018

The operation process of the automobile motor magnetic tile is mainly to send two-phase alternating current into two groups or four sets of motor coil windings, so that a rotating magnetic field can be formed in the inner machine, and the rotating magnetic field generates an induced current in the rotor of the motor, and the induction The magnetic field generated by the current is opposite to the direction of the rotating magnetic field, and is pushed and pulled by the rotating magnetic field into a rotating state.

The magnetic energy of the motor motor is larger, the better, so that the working efficiency of the motor can be greatly improved. The better the squareness of the demagnetization curve of the product, the smaller the dynamic loss of the motor of the whole device. The higher the resistivity of the ferrite, the smaller the eddy current loss.

  

The permanent magnet ferrite of the automobile motor magnetic tile has a small temperature coefficient, and can have its good temperature stability to a certain extent at a high temperature, and the larger the magnetic energy Φ, the better, which will greatly improve the working efficiency of the motor. The better the squareness of the demagnetization curve, the smaller the dynamic loss of the motor, and the higher the resistivity of the ferrite magnet, the smaller the eddy current loss.
