How to maintain the motor of multi-purpose oscillator?

How to maintain the motor of multi-purpose oscillator? We know that the motor is widely used in our instruments and equipment, and the large and small motors also play an important role in various instruments and equipment, so the quality of the instruments and equipment often depends on the quality of the motor, but even the best motor can be damaged under abnormal use, such as the common speed regulating multi-purpose oscillator in our laboratory Its work is mainly driven by the motor If the motor is damaged, it will be paralyzed In daily use, how can we extend the service life of the motor? Let me simply say next First of all, it is necessary to prohibit overload For example, our speed regulating multi-purpose oscillator verifies that the load is 20kg, but the load is 40kg for a long time This will lead to the decrease of motor speed, the increase of current, the increase of temperature and the overheating of winding coil If the motor is overloaded for a long time, the insulation of the motor will burn out due to aging under high temperature, which is the main reason for the motor burn out The second is to keep the working environment of the laboratory clean and good ventilation environment, because if these dust, oil and water are inhaled into the motor, a short-circuit medium will be formed, the conductor insulation layer will be damaged, the turn to turn short circuit will be caused, the current will increase, the temperature will rise and the electric motor will be burned The third is to maintain the relative balance of the three-phase current, because the difference between the average value of any phase current and other two-phase current in the three-phase current is not allowed to exceed 10%, so as to ensure the safe and normal operation of the motor Finally, we should learn to find out that noise and peculiar smell are often the omen of motor abnormal operation and failure We must find out and find out the causes in time to eliminate them, otherwise, we will delay the opportunity, expand the failure, and lead to the major accident of burning the multi-purpose vibrator motor.
