Lead Wiring Type

Description

The heavy-duty AC braking motor is an integrated power and braking product designed for high-load, continuous operation conditions. It is suitable for industrial equipment requiring high output power, operational stability, and reliable braking. This model uses a 5RK motor type, featuring a reinforced design in terms of electromagnetic structure and mechanical strength. With a rated power of 40W, it can maintain stable output under heavy load conditions, providing sufficient driving margin for the equipment and reducing the impact of load fluctuations on system operation.
The motor supports a wide voltage input range of 110V–380V, allowing for flexible matching to power supply standards in different regions and industries, facilitating deployment and use in various scenarios. The motor integrates a highly reliable braking mechanism, which can quickly respond and output a stable braking torque in the event of power failure or shutdown. This effectively locks the load position, preventing slippage of heavy-duty systems due to inertia or external forces, thereby improving the safety and controllability of the entire machine.
This product can be paired with a reduction ratio range of 3–200K, enabling flexible switching from medium-speed operation to low-speed, high-torque output according to actual application needs. Through reasonable matching with the reduction mechanism, the motor can convert higher power into greater effective torque, meeting the requirements of heavy-duty conveying, lifting, pushing, and pulling applications. Simultaneously, the reduction system and braking unit work together to reduce mechanical shock during starting and braking, improving the overall smoothness of system operation.
