Analysis of the principle of heating of the motor of the Hydraulic Dumping Tricycle

The use of Hydraulic Dumping Tricycle in our daily life is very common. For its use, it will cause the phenomenon of motor heating. For this phenomenon, what is the reason? The editor of the Tricycle Motorcycle Let me give you a brief introduction to the content of this aspect.

All kinds of motors we usually see have iron cores and winding coils inside. The winding has resistance, and loss will occur when power is applied. The loss is proportional to the square of the resistance and current. This is what we often call copper loss. If the current is not a standard DC or sine wave, harmonic loss will also occur; the core has hysteresis The eddy current effect also produces loss in the alternating magnetic field, and its magnitude is related to the material, current, frequency, and voltage, which is called iron loss. Both copper loss and iron loss will be manifested in the form of heat, and then affect the power of the motor. Stepper motors usually seek precision and torque output, the power is relatively low, the current is usually relatively large, and the harmonic components are high, and the frequency of current alternating changes with the speed, so stepper motors generally have heat, and the situation is higher than usual. The motor is grim.
Although motor heating usually does not affect the life of the motor, it is unnecessary for most customers. But when it is serious, it will bring some negative effects. If the thermal expansion coefficient of each part of the motor is different, the change of the layout stress and the small change of the internal air gap will affect the dynamic response of the motor, and it will easily lose the step at high speed. Another example is that some occasions do not allow excessive heating of the motor, such as medical equipment and high-precision testing equipment. Therefore, the heating of the motor should be controlled as necessary.
Therefore, for Hydraulic Dumping Tricycle, after the phenomenon of motor heating occurs, correct measures must be taken in time. The above is the analysis of the reasons for the heating of the motor analyzed by the editor of the Tricycle Motorcycle. I hope you have read our After the introduction, you can also have a sufficient understanding of the content in this area.
