Product Description
The gear motor for the electric park brake (EPB) is designed and developed for designated customers. This is only the showcase. Besides selling standard products, ZHAOWEI can provide design, research and manufacture for customers based on their specific needs as well. With its benefits of small size, low noise level, high torque, quick response, and long service life, the EPB actuator made by ZHAOWEI has always be the ideal choice of manufacture.
Based on the analysis of the electric park brake system, we modify the gear tooth profile to make it respond in a short time and realize high torque under the large current. To achieve low noise and high torque with a small volume, the ZHAOWEI gear motor comes to reduce the impact of noise and vibration on the gear module performance.
above specifications just for reference and customizable according to requirements.
product details show:


To solve this problem, we try to add an intelligent self-locking function to the circuit breaker controller of the electronic meter. Taking into account that the internal space of the smart controller of the electric meter is relatively small, the gear motor should drive the stable operation of the loop control system in a limited space, and it is only allowed to rotate in the specified direction and cannot go backwards. We use 10mm planetary gearheads and turbine inserts to be injected into the loop controller gearbox, so that the transmission structure has the characteristics of small size, large torque and can meet the needs of self-locking function. The loop controller gearbox in this scheme can realize the reverse self-locking of the electric meter, which can only transmit the power of the active end of the motor without responding to the external load, thereby isolating the external load from the smart meter's own mechanism. In case of possible damage, the smart meter can be stopped at the gear motor (also called the gear motor of the loop controller) to increase the service life of the smart meter, solve the problem of data loss when the power is suddenly cut off, and protect the safety of the data.
