Power saving analysis using magnetic slot wedge
● Motor efficiency can be improved due to reduced motor losses.
● If the output power is constant, after the loss is reduced, the input active power of the motor can be reduced, and the input current is also reduced: if the input active power is constant, the output power of the motor can be increased, which is equivalent to increasing the motor capacity. .
●Because the magnetic flux wedge can conduct a part of the magnetic flux inside, the magnetic flux distribution in the air gap tends to be uniform, so the motor noise and vibration can be reduced, and the vibration of the motor can be reduced, and the bearing life can be prolonged.
●The slot is placed in the magnetic slot wedge, and the effect is equivalent to the shortening of the effective air gap length of the motor. Therefore, the field current can be reduced and the no-load current can be lowered.
●Because the motor loss is reduced, the motor's heat is reduced, so the motor temperature rise is reduced, which can extend the life of the motor.
Magnetic groove wedge application example
A high-voltage motor sold by a motor factory affected production due to the increase in motor temperature. After the magnetic wedge is used, the temperature of the motor is obviously reduced, and the noise is also significantly reduced, which ensures the normal operation in summer.
It can be seen that the application of the magnetic slot wedge to transform the motor is an effective power saving method. However, the application of the magnetic wedge must be moderate, to avoid causing excessive increase in the leakage magnetic flux of the slot and resulting in insufficient starting capability.
