advantage
|
|
high efficiency
|
The motor enjoys rated efficiency of 94% and wide constant power range with over 80% efficiency area accounting for 85% of the total efficiency area.
|
|
High reliability
|
By adopting new rare earth material and reasonable design, it effectively overcomes the irreversible demagnetization of permanent magnet so as to ensure safe and reliable operation under various working conditions.
|
|
high power density
|
Permanent magnet synchronous motor is able to provide more power output and acceleration speed for new energy vehicle compared with other motors with the same mass and volume.
|
|
low maintenance cost
|
The full-enclosure structure creates clean and unpolluted environment within the motor and reduces the maintenance cost in its life-cycle operation process.
