How to properly maintain the motor of the speed multi-purpose oscillator?

We know that motors are widely used in our instruments and equipment. Large and small motors play a pivotal role in various instruments and equipment. Therefore, the quality of instruments and equipment often depends on the quality of the motor, but no matter how good the motor is When the leaf is damaged under abnormal use, such as the common speed 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 do we extend the service life of the motor? Let me briefly talk about it below.

First of all, it is necessary to prohibit overload. For example, our speed-regulating multi-purpose oscillator has an approved load of 20KG, but working with a load of 40kg for a long time will cause the motor's speed to drop, current to increase, temperature to rise, and winding coils to overheat. If the motor is overloaded for a long time, the motor will burn out due to aging failure at high temperature, which is the main reason for the motor to burn out.

The second is to keep the laboratory working environment clean and well ventilated, because if these dust, oil, and water are sucked into the motor, it will form a short-circuit medium, damage the wire insulation, cause a short circuit between turns, increase current, and temperature Elevated and burned the motor.

The third is to maintain the relative balance of the three-phase current, because the difference between the current of any one phase and the average value of the other two-phase currents in the three-phase current is not allowed to exceed 10% in order to ensure the safe and normal operation of the motor.

Finally, during the experiment, we must also learn to discover that sometimes noise and peculiar smell are the precursors of abnormal motor operation and malfunction. We must find out and find out the cause in time to eliminate it, otherwise it will delay the opportunity, enlarge the malfunction, and cause burnout. The major accident of the speed multi-purpose oscillator motor.
