Lead Wiring Type

Description

The high-torque AC brake motor is a drive product designed for high-load, demanding braking applications. It is suitable for industrial automation applications requiring higher starting torque, braking reliability, and operational stability. This model utilizes a 3RK motor structure, specifically optimized for structural strength and output capability. With a rated power of 15W, it maintains stable power output under continuous operation and frequent start-stop conditions, providing ample driving margin for equipment.
In terms of electrical configuration, this high-torque AC brake motor supports a wide voltage input range of 110V–380V, allowing for flexible adaptation to different regions and power supply systems, reducing the difficulty of electrical adaptation in cross-project applications and equipment export. The motor integrates a highly reliable braking unit, which responds quickly and generates stable braking torque during power outages or emergency stops, effectively locking the load position and preventing displacement caused by inertia or gravity, thereby improving the overall system safety and controllability.
This product can be paired with a reduction ratio range of 3–200K, achieving high torque output while maintaining flexibility in speed adjustment. By rationally configuring the reduction ratio, the motor output can be converted into greater effective torque, suitable for applications requiring low speed and high torque operation, such as lifting mechanisms, heavy-duty conveying devices, and actuators requiring precise positioning. The reduction mechanism works in conjunction with the motor braking system to reduce braking impact, improve operational smoothness, and extend the service life of critical components.
