As we all know, screw elevator drives are very flexible.It can be driven manually or by sprocket, chain, belt, or by motor.There are many options for motors, stepper motors, servo motors, etc.So the use of screw lift is very flexible.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 lift is very large.The number of input revolutions is allowed to be 1500r/min, so everyone should pay attention when choosing a motor.
Some customers report that noise sometimes occurs when the electric motor is connected to the elevator.Our technical engineers analyzed these situations and gave some solutions to motor noise. Today we will tell you some methods. If the customer uses it when motor noise occurs, he 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 excitation voltage is low, which causes the motor to start or start slowly, which produces a boring sound.In this case, we need to determine whether it lacks phase or whether the voltage is low.If there is a lack of phase, we need to find the cause of the lack of phase to correct it.If it is a voltage problem, we need to increase the field voltage or shorten the cable length.
The second point is to produce mechanical noise.This noise is composed in many ways.It may be that the core of the rotor is loose, or the gap of the rotor is uneven, or the friction caused by the friction between the fan and the housing is too tight, and the brake may be locked.sound.In these cases, we need to return to the factory for repairs or replace the brake components to solve the problem.
