YD Series750/1500/3000 r/min Motor
The YD Series multi-speed three-phase induction motor is a high-efficiency, energy-saving solution designed for industrial applications requiring variable speed operation. This series offers three synchronous speed options—750, 1500, and 3000 r/min—achieved through pole-changing technology that alters the stator winding configuration. By adjusting the number of poles, the motor can seamlessly transition between speeds to match load demands, eliminating the need for external speed control devices and reducing system complexity. Key features include a compact design, low noise levels, and high starting torque, making it suitable for machinery such as pumps, fans, and conveyors. The motor adheres to IEC and DIN standards, ensuring interchangeability with global counterparts, while its IP44/IP55 protection rating allows operation in dusty or humid environments. With power ratings spanning 0.45 kW to 82 kW and voltage options from 380V to 660V, the YD Series accommodates diverse industrial requirements. Additionally, its F-class insulation (rated for 155°C) enhances reliability and lifespan, while optional electromagnetic brakes enable precise stopping for critical applications. The series supports direct-on-line starting and offers customization for altitude, ambient temperature, and installation types, making it a versatile choice for energy-efficient speed regulation in manufacturing, mining, and textile industries.

The YD series 750/1500/3000 r/min triple-speed motor is a versatile high-efficiency drive component engineered for reducer systems, supporting switchable 8-pole (750 r/min), 4-pole (1500 r/min), and 2-pole (3000 r/min) operations to adapt to multi-scenario industrial demands. Its advanced triple-winding structure ensures precise torque output at low speeds, stable power transmission at medium speeds, and high rotational efficiency at high speeds, forming a reliable synergistic system with reducers.
A standout advantage is its adaptive load regulation capability, which maintains optimal performance across speed levels—delivering strong torque for heavy-load tasks at 750 r/min and energy-saving operation at 1500/3000 r/min. The motor’s smooth speed-switching mechanism reduces mechanical impact during mode conversion, effectively protecting reducer gears and bearings from premature wear, while its optimized electromagnetic circuit minimizes noise and energy consumption.
Adopting F-class insulation and IP55 protection rating, it excels in harsh working environments such as manufacturing, logistics, and construction, resisting dust, humidity, and continuous temperature fluctuations. Its compact design and standardized mounting interface enable seamless integration with various reducer models, lowering installation complexity and long-term maintenance costs.
Equipped with high-precision dynamic balancing and a reinforced heat dissipation system, it ensures continuous stable operation even under prolonged heavy-load conditions, extending the service life of both the motor and the entire transmission chain. This combination of multi-speed flexibility, load adaptability, and structural durability makes it an ideal choice for equipment requiring versatile speed adjustment and high-reliability transmission.
