The cause of noise after the motor is connected to the screw jack
The screw jacks are flexible in driving, either by manual drive or by sprocket, chain, belt, etc., or by motor drive. There are also many choices of motors, stepper motors, servo motors, and so on. Therefore, the screw jack (screw lift) is still very flexible in use. At the same time, the elevator itself has a reduction ratio, so it can drive very heavy objects with a small force, but it should be noted that the maximum allowable input rotation speed of the elevator is 1500r/min, so everyone must pay attention when selecting the motor.
Some customers report that noise sometimes occurs when the motor is connected to the elevator. Our technical engineers have analyzed these situations and given some solutions to the motor noise. Today we will tell you some of these methods so that if the motor noise occurs, the customer can solve it in time.
The first point is the electrical noise generated. The reason for this noise is that the motor is out of phase or the field voltage is low, which causes the motor to start up or start slowly, which causes a boring sound. In this case, we need to find out whether it is missing phase or The voltage is low. If there is a phase loss, we need to find the reason for the lack of phase to correct it. If it is a voltage problem, you need to increase the voltage in the field or shorten the length of the cable.
The second point is the generation of mechanical noise. This kind of noise is composed in many ways. It may be that the core of the rotor is loose, or the gap of the rotor is not uniform, or the friction caused by the friction between the fan and the casing is too close, and the brake may be locked. the sound of. In these cases we need to go back to the factory for repair, or replace the brake assembly to solve it.
