The YEJ/YDEJ series 750 r/min 8-pole motor is a heavy-duty braking motor exclusively engineered for Weigao reducers, specializing in stable ultra-low-speed, high-torque output with integrated reliable braking performance. It caters to the strict requirements of precision load control and safe stop in industrial scenarios that demand prolonged load holding, slow-speed operation, and frequent start-stop cycles, such as heavy machinery and material handling systems.
A distinctive advantage is its enhanced electromagnetic brake with high-torque retention capability, which maintains steady braking force without slippage even under heavy loads, effectively protecting Weigao reducers from inertial damage. The brake adopts high-wear-resistance friction plates and a heat-dissipating structure, reducing thermal accumulation during continuous braking and extending the service life of both the motor and reducer.
Optimized for low-speed efficiency, it features a refined rotor structure and precision winding design, minimizing no-load loss and improving power factor at ultra-low speeds. Equipped with F-class insulation and IP55 protection, it resists harsh industrial conditions including dust, moisture, and temperature variations, ensuring stable operation in harsh working environments.
With standardized mounting dimensions and compatible flanges, it integrates seamlessly with various Weigao reducer models. Its low-vibration design (dynamic balancing grade G2.5) and noise reduction structure reduce mechanical stress on the reducer’s internal components, balancing safety, durability, and operational efficiency for heavy-duty industrial applications.
