Reasons and solutions for abnormal operation of deceleration motors

Micro gear reduction motor refers to the combination of a gear motor and a reduction gearbox. The reduction motor is generally driven by the power of high-speed operation of the motor through the small gear on the input shaft of the reduction motor to drive the large gear to achieve a certain reduction in speed. By using multiple stages, the speed can be greatly reduced and the output torque of the reduction motor can be increased. Its main principle is to use the transmission of gears at all levels to achieve the purpose of reducing speed and achieving "force reduction".

Micro gear motors have diverse shapes, uses, and power, and can be customized. They have the characteristics of low noise, high torque, small size, low energy consumption, and space saving. Due to their tight manufacturing, integrated assembly, durability, and mechatronics integration, they are suitable for various environmental factors and are widely used in printing machinery, conveying machinery, food machinery, labeling machinery, packaging machinery, and so on.

During the operation of a gear reduction motor, as electrical energy is converted into mechanical energy, a portion of the electrical energy is also converted into thermal energy, resulting in abnormal heating (temperature rise) of the gear reduction motor. If the temperature exceeds 80 degrees, it is considered abnormal heating. The normal temperature rise of the motor is around 60 degrees. After a period of use, the cause of excessive vibration in the gearbox is due to the imbalance of the transmission mechanism or the mechanical balance of the rotor, leading to heating. How to solve this heating problem and how to avoid it? Next, we will take you to understand.

1. If the deceleration motor operates continuously for a long time and is constantly overloaded, it will generate heat. In order to avoid abnormal heating of the motor, it is necessary to choose a motor with sufficient power to prevent overloading.

2. Foreign objects are stuck in the delivery area of the motor, excessive dust enters the interior of the motor, and the insulation of the coil is low, causing an increase in motor heating. In case of abnormal heating of the motor caused by this situation, maintenance of the deceleration motor can be strengthened, and protective devices for the entire equipment can be installed. In cases where the motor needs to work in an exposed environment, it is necessary to install protective devices to prevent foreign objects from entering the interior of the motor.

During use, if the alignment between the reducer and the passive shaft exceeds the required range, it will cause excessive radial force on the output shaft of the reducer, wear the oil seal and eccentric bearing, and generate a large amount of heat.

4. Lubrication problems can cause the gearbox to heat up, with insufficient lubricating oil and a large amount of heat generated by friction. Excessive lubricating oil and stirring can result in power loss and a large amount of heat generation. It is necessary to replenish lubricating oil in a timely manner, and the most appropriate time is to change the lubricating grease after running for about 3000 to 5000 hours.

If the deceleration motor cannot operate normally or runs slowly after starting, it is necessary to check whether it is a problem with the circuit breaker or contactor. High power supply voltage may also cause the deceleration motor to heat up.
