The YE3 series 1500 r/min 4-pole motor is a high-efficiency drive component designed for Weigao reducers, core function being delivering stable mechanical power with precise speed control to match the reducer’s torque conversion needs in industrial transmission. It integrates optimized electromagnetic winding technology to realize efficient energy conversion, covering a wide power range to adapt to diverse Weigao reducer models and application scenarios.
A unique advantage is its excellent power factor retention, maintaining above 0.88 at partial load to reduce reactive power loss for the entire Weigao reducer system. Its lightweight cast aluminum housing enhances heat dissipation performance, avoiding thermal accumulation during long-term continuous operation and extending the synergetic service life.
Different from conventional motors, it adopts a maintenance-free bearing design with high-temperature resistant lubricant, eliminating regular lubrication work and reducing maintenance costs for paired Weigao reducers. The motor’s low vibration characteristic (dynamic balancing grade G1) minimizes mechanical impact on the reducer’s internal gears and bearings.
It features standardized flange and shaft dimensions for seamless integration with Weigao reducers, simplifying installation and replacement. With strong voltage stability and compliance with global industrial standards, it balances efficiency, reliability and cost-effectiveness, making it an ideal drive solution for Weigao reducer-equipped equipment like pumps, fans and conveyors.
