Motor should be used under working conditions of 5ºC-40ºC and below 90%RH.
Motor should be stocked under conditions of -10ºC to 60ºC and below 90%RH.


The motor adopts IPM structure, energy efficiency is in line with the IE4 standard,  reduced 1-2 frame size compared with the same power asynchronous motor. The products meet CE, RoSH certification Power 750W Speed 1500r/min Insulation F Protection IP55 Duty S1.
The motor without loss of excitation, uses a high performance silicon steel sheet to reduce iron loss; uses IPM structure to increases the torque density so as to reduce the copper loss; uses high-quality aluminum alloy, to make the products lighter; uses high performance fan to improve the heat dissipation capability.
