What to do if the motor of the scissor lift platform heats up


When using the elevator, the motor is found to be very hot, so don't worry and find out why. Later, I was thinking of ways to deal with this problem. Each scissor lift channel must be operated by a motor, so the motor is the standard installation equipment for the scissor lift channel. Under normal circumstances, the electric lifting channel can only use the motor when it is elevated, so the working time is short, and the motor is generally not prone to some abnormal phenomena.

As this kind of digitally implemented components, electric motors are widely used in motion control systems. Many customers who use the scissor lift channel feel that the motor will be very hot during operation, and they are worried. I don’t know if this behavior is normal. In fact, heating is a common phenomenon of motors, but how much heating is normal, how to reduce the heating of hydraulic lifting motors to lower?

How does the electric motor get hot? Lin Lin's general motor used by people is full of transformer iron core and winding electromagnetic coil. There are resistors in the winding, and electricity will constitute consumption. The consumption standard is proportional to the square meter of the resistor and the amount of current. It is often referred to as copper loss. If the amount of current is not a standard DC or sine wave, it will also form a harmonic Wave consumption; the iron core has hysteresis eddy current effect, which will also constitute consumption in the electromagnetic field of the alternating electric field. Its standard is related to the raw material, current amount, frequency, and operating voltage. This is called iron loss. Copper loss and iron loss are mainly reflected by the hot method, thereby damaging the high power of the motor. The motor generally pursues positioning accuracy and torque output, low power, high current, high harmonic content, and AC frequency changes with speed. Therefore, hydraulic elevator motors generally have more severe heating conditions than general-purpose AC motors.
