Micro motor protection device with opening and closing position indicator

Abstract

The invention discloses a micro-motor protection device with an opening and closing position indicator, which belongs to the technical field of micro-motor protection, and includes a support assembly, a heat dissipation assembly, and a heat dissipation auxiliary assembly. A heat dissipation component is provided, and a heat dissipation auxiliary component is arranged under the heat dissipation component. The invention is scientific and reasonable, and is safe and convenient to use. The device utilizes the vibration force of the micro-motor to effectively cool down the micro-motor itself, without the generation of external energy consumption. The whole process uses the change of motor temperature and eccentricity to realize the automatic opening and closing effect of the circuit, which is environmentally friendly and has no consumption. When the micro-motor fails and causes eccentricity during operation, the micro-motor will generate large vibrations and produce intermittent circuit connection effects to prompt Operators need to overhaul or replace the micro-motor failure, which is conducive to the long-term use and maintenance of the micro-motor.

Description

technical field [0001] The invention relates to the technical field of micro-motor protection, in particular to a micro-motor protection device with an opening and closing position indicator. Background technique [0002] my country's micro-motor industry was founded in the 1950s. It was originally to meet the needs of national defense weapons and equipment. It has gone through the stages of imitation, self-design and research and development. It has a history of more than 40 years. There are more than 1,000 supporting manufacturers, more than 100,000 employees, and a total industrial output value of more than 10 billion yuan. The micro-motor industry has become an indispensable basic product industry in the modernization of the national economy and national defense. The domestic demand for micro-motors is growing. The main micro-motor products in my country are brushed permanent magnet DC motors, shaded pole motors, stepping motors, Small-power AC motors, AC-DC series motors...

AI Technical Summary

Problems solved by technology

[0003] However, long-term operation of the micro-motor will undoubtedly cause heat, which will cause serious wear and tear on the internal parts of the motor and affect the service life of the micro-motor. If the micro-motor cannot be used continuously for a long time, it will greatly limit the use environment of the micro-motor, and The small size of the motor is not easy to be found when eccentric vibration occurs in the operating environment, so people need a micro-motor protection device with an opening and closing position indicator to solve the above problems
