The YD series 500/1000 r/min dual-speed motor is a high-torque drive component customized for Weigao reducers, featuring switchable 12-pole (500 r/min) and 6-pole (1000 r/min) operations to meet ultra-low and medium-speed industrial needs. It adopts a heavy-duty dual-winding design, which delivers exceptional torque retention at 500 r/min for heavy-load tasks and smooth power output at 1000 r/min, forming a synergistic transmission system with reducers.
A core advantage is its enhanced mechanical rigidity, which withstands high load pressure at ultra-low speeds without deformation, reducing wear on reducer bearings and gears. The motor’s intelligent speed-switching control minimizes voltage fluctuation and impact force during conversion, ensuring stable operation of the entire transmission chain and extending service life.
Equipped with H-class insulation and IP55 protection, it performs reliably in harsh environments like mining, construction machinery, and bulk material handling, resisting dust, moisture, and prolonged high temperatures. Its standardized mounting dimensions and compatible interface enable seamless integration with various Weigao reducer models, simplifying installation and maintenance processes.
With precision dynamic balancing and an upgraded heat dissipation system, it maintains consistent performance during long-term continuous operation, avoiding overheating-induced failures. This combination of ultra-low-speed torque, medium-speed efficiency, and robust structure makes it an ideal choice for equipment requiring flexible speed adjustment and heavy-load endurance.
