The YVF-22 motor is applied as the driving motor of mining VF AC trolley locomotive of first-stage driving (once of speed variation) of Model CJY7-6.7.9 and CJY10-6.7.9. It has features of simple structure energy conservation maintenance-free smooth operation capability and high efficiency.
Usage Notice
The motor adopts Class F insulation and the temperature rise limit (resistance method) of its stator winding is evaluated according to 155K.
When the motor is at an ambient temperature of 40°C or below the allowable temperature of the rolling bearing (thermometer method) should not exceed 95°C.
