The high magnetic flux and high magnetic energy product of high performance NdFeB can greatly improve the accuracy and sensitivity of motor control, and the speed range can be greatly increased to more than 1000:1, which makes the motor start more smoothly and control more accurately, and the loss of frequent start and variable speed is smaller.
Therefore, high performance NdFeB magnets can save energy significantly, and further reduce energy consumption by more than 5PCT compared with ordinary NdFeB magnets, and the average energy saving efficiency can reach more than 15 percent , which can save 25 percent -30 percent in the application fields such as inverter air conditioner, elevator, etc. that need frequent start/stop and change working speed.
