Thus the motor is “hot” at max load, and “cool” at no load. PM motors, conversely, derive the field from high energy permanent magnets, so that no power is required to build the motor field and more power can be devoted to torque generation. When the flux must be reduced, however, power must be applied just to lower the field so that PM motors at high speed need some current even at no load.

Max load at top 到顶限重
Thus the motor is "hot" at Max load, and "cool" at no load.
因此，电动机的“热”在最大负荷，和“酷”在无负载。
Note: The power supply shall be test at max AC voltage (270Vac) and min load or no load.
应该在最大交流输入电压270伏和轻载，空载下测试。
5Arms max At any input voltage and rated, DC output rated load.
当输入交流电压为额定值的下限时，输出电压负载满载，最大输入交流电流2.5A。
