How to equip a servo motor with a reducer?
In the process of selecting a reducer, we need to clarify the interfaces of two reducers through drawings. At the same time, it is also required that the structural form and external dimensions of the reducer can meet the equipment requirements and be connected to the selected servo motor.

Application of self-locking function of worm gear reducer
It is particularly important to determine the self-locking performance of worm gear reducers when it is required. But in practical applications, self-locking is often difficult to determine. For example, in the process of designing a high-pressure vacuum switch tube exhaust station, its reducer is a worm gear mechanism (without a brake). When lifting the insulation cover, turn off the motor power and the mechanism usually locks immediately, preventing the insulation cover from lowering; However, during the descent movement, when the motor power is turned off, the mechanism can sometimes lock itself, sometimes it cannot lock itself, and even accelerate the descent, completely losing its self-locking ability. This phenomenon is mainly due to the influence of various factors in practical applications, such as manufacturing accuracy, lubrication conditions, load changes, etc.

What is the reason for the high no-load current of the gearbox?
High temperature environment can make it difficult for the motor and reducer to dissipate heat, resulting in an increase in the resistance of the motor winding and an increase in no-load current. At the same time, high temperature can also affect the performance of the lubricating oil inside the gearbox, reduce the lubrication effect, and increase the frictional resistance. A humid environment may cause a decrease in the insulation performance of the motor, leading to leakage and an increase in no-load current. In addition, humid environments may also cause rusting inside the gearbox, increasing operational resistance.
