Cause of motor heating of medium frequency tube bending mach

The cause of motor heating of medium frequency pipe bender can be analyzed and explained from many aspects. The following are some that cause motor overload: When the motor load exceeds its rated capacity, the current flowing through the coil of the motor will increase, resulting in heating. Common causes include excessive workload, low voltage, and excessive mechanical resistance.

2. Poor insulation: The insulating material of the motor is used to isolate the wires and metal parts to prevent the current from leaking into the external environment. If the insulation is aged, cracked or damp, current may flow out through the insulation, causing the motor to heat up.

3. Hysteresis loss of steel parts: The rotating part of the motor is usually composed of an iron core, and these parts will produce hysteresis loss when the magnetic field changes. This loss causes the core to heat up, which is transmitted throughout the motor.

4. Motor rotor imbalance: When the motor rotor is unbalanced, it will cause a lot of vibration and friction, resulting in additional heat.

(5) Internal friction of the motor: the friction parts inside the motor, such as bearings, gears and transmission devices, etc., if poor lubrication or serious wear, it will lead to increased friction and generate additional heat.

6. Poor motor design: The design of the motor is unreasonable, such as the size of the coil and the iron core does not match, the cooling system is imperfect, etc., which may lead to the motor heating.

7. Driver problems: motor driver failure, power supply voltage instability, control signal abnormalities, etc., may lead to motor heating.

8. The ambient temperature is too high: if the working ambient temperature of the medium frequency pipe bending machine is too high, it will lead to poor heat dissipation of the motor, and then cause the motor to heat up.

9. Excessive current through the winding: When the current of the motor winding exceeds the design capacity, it will cause the motor to heat up.

10. Poor heat dissipation of the motor: if the cooling system of the motor is poor or blocked, the internal heat of the motor can not be effectively distributed, resulting in heating problems.

The above are some reasons that may cause the motor to heat up in the medium frequency pipe bender, and each reason can be further discussed in detail. To solve the motor heating problem, it is necessary to consider all the above factors, inspection, testing and maintenance.
