The frequency conversion motor according to the JB/T7118-2014 standard production, in the design of stator winding groove and stator windings of the distribution of special considerations, in order to meet the requirements of PWM inverter power supply. The electric motor's electromagnetic load design also considers a certain margin, which can guarantee the overload ability of the motor at high frequency, and can keep constant torque output when the low frequency is running. The insulation structure of electric motor is designed, and the effect of the hig......
