It is very important to determine the thickness of magnetic steel in the motor
It is important to determine the thickness of magnetic steel in motor? Why? Today, the supplier of motor magnet will tell you how important it is.
We all know that the magnetic field of the motor is mainly generated by the magnetic steel of the motor (Arc magnet, Multi-pole magnetic ring). The working magnetic flux generated by the magnetic steel is more lager,the total number of armature conductors of the rotor can be reduced accordingly. This is very beneficial to the motor.
On the one hand, the armature resistance of the motor can be reduced accordingly, In this way, the copper loss of the motor can be reduced accordingly too, and the efficiency is correspondingly increased.
On the other hand, the total number of conductors required for the rotor of motor is correspondingly reduced, the slot slow rate of the motor is correspondingly reduced, this make it easy to wire the motor rotor. If the magnetic flux of the motor is increased under the premise of the same magnetic steel, the volume of the magnetic steel is increased. The volume of the magnetic steel is determined by the thickness and length of the magnetic steel. The length of the magnetic steel is determined by the length of the rotor. So the main thing is to determine the thickness of the magnetic steel. When the thickness of the magnetic steel is thin, the magnetic steel is easily demagnetized and the processability is not good. When the thickness of the magnetic steel is thick, the magnetic properties of the motor cannot be greatly improved. Instead, it consumed more material of magnetic steel, and the cost is greatly improved. Therefore, the thickness of magnetic steel must be determined.
