Today we will talk about the motor magnetic tile problem, how to affect the performance of motor magnetic tile? From this, we draw the following questions:
ⅰ. Sintered NdFeb strong magnetic tile: temperature resistance of about 200 degrees, magnetic force can meet the working temperature of ordinary motor, and the price is moderate and cheap. In general, it is cost-effective.
ⅱ. Ferrite motor magnetic tile: temperature resistance can reach 300 degrees, but the magnetic force may not meet the magnetic force requirements.
ⅲ.Bonded NdFeB magnetic tile: the same as sintered NdFeB strong magnetic tile. But bonded NdFeB magnetic tiles are easy to form. It can be customized to make it difficult to process the special-shaped magnetic tile.
ⅳ. Samarium cobalt high temperature resistant magnetic tile: the temperature resistance is about 250-350 degrees, and the magnetic force can meet the working temperature of most motors. However, because the material is rare earth material, the price is relatively expensive. But compared with NdFeB magnetic tile, it is more suitable for working under a high temperature environment, and its temperature resistance coefficient is also more stable.
ⅰ. The stronger the magnetic power of the motor magnetic tile → the greater the torque → the lower the speed;
ⅱ. The weaker the magnetic power of the motor magnetic tile → the smaller the torque → the higher the speed.
ⅰ. Because the magnet with weak magnetic in the high voltage environment, the moment is small, it almost can not be used;
ⅱ. Weak magnetic motor magnetic tile is used in the motor voltage is relatively small;
ⅲ. Strong magnetic motor magnetic tile is used in the high voltage motor.
Generally speaking, the stronger the magnetic power of a motor magnetic tile, the greater the power, so the motor often chooses NdFeB strong magnetic tile.
The temperature of the working environment of the motor will not affect too much as long as it does not exceed the limit value of the motor magnetic tile.
