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 high frequency of PWM converter is considered, especially the inter turn insulation. The test value is far beyond the requirements of JB/Z346. Cooling method can be based on user needs, the use of the motor's own wind or individual axial flow fan forced ventilation. Motor speed range: reference frequency 50 Hz motor, constant torque speed 5-50Hz, constant power speed 4-pole motor 50-130Hz, six pole motor 50- 200Hz; reference frequency 60Hz motor and constant torque speed 6-60Hz, constant power speed a four pole motor 60-130Hz, six pole motor 60-200Hz.
Use conditions: elevation is equal to or less than 1000m, ambient temperature is less than or equal to 40 DEG C, relative humidity is less than or equal to 90%.
