Yvf2 (80--225) Series Variable Frequency Adjustable Speed Three Phase Asynchronous Motor

Product Description:

      YVF2 series variable frequency speed three-phase asynchronous motor is a variable frequency speed three-phase asynchronous motor with frequency converter as power supply. By changing the frequency of power supply, the speed of motor can be adjusted smoothly to save energy and control automation.
       
      YVF2 series motors have higher efficiency, wide speed range, high accuracy, stable operation and convenient maintenance. Its installation size meets the IEC standard, and its shell protection level is IP54. The motor has an external fan cooler. The motor quota is a continuous quota based on the continuous working system S1. The rated voltage is 380V; F-class insulation, rated frequency is 50HZ; motor can continuously adjust speed in the range of 3-100HZ, 3-50HZ is constant torque operation, 50-100HZ is constant power operation. If the maximum torque is greater than the value in the table or the seat number of YVF2-160M or below does not require an external fan cooler (lower power use), it should be noted in the order.

Maintenance method	Professional motor maintenance center motor maintenance process: cleaning stator and rotor - replacing carbon brush or other parts - vacuum F pressure dipping paint - drying - Calibration balance. 1. Use environment should be always dry, motor surface should be kept clean, air intake should not be hindered by dust, fibers and other obstacles. 2. When the thermal protection of the motor continues to operate, it should be ascertained whether the fault comes from the motor or the overload or the setting value of the protective device is too low. After eliminating the fault, it can be put into operation. 3, ensure that the motor is well lubricated during operation. The general motor runs for about 5000 hours, that is to say, lubricating grease should be added or replaced. When bearing overheating or lubricating deterioration is found in operation, the hydraulic pressure should change lubricating grease in time. When replacing grease, the old grease should be removed, and the oil groove of bearing and bearing cover should be washed with gasoline. Then ZL-3 lithium grease should be filled with 1/2 (2 poles) and 2/3 (4 poles, 6 poles and 8 poles) of the cavity between the inner and outer rings of the bearing. 4. When the life of the bearing is over, the vibration and noise of the motor will increase obviously. When the radial clearance of the bearing reaches the following value, the bearing should be replaced. 5, when removing the motor, it is OK to remove the rotor from the shaft extension or the non extension end. If it is not necessary to unload the fan, it is more convenient to take out the rotor from the non-axle extension end. When pulling out the rotor from the stator, the stator winding or insulation should be prevented from being damaged. 6. When replacing the windings, the form, size, turns and gauges of the original windings must be recorded. When these data are lost, they should be obtained from the manufacturer and the original designed windings should be changed at will, which often deteriorates one or several performance of the motor or even makes it impossible to use them.
