Raydafon Group offers a comprehensive range of high‑efficiency three‑phase asynchronous motors, designed to meet international energy efficiency standards and deliver reliable performance across industrial applications. Our portfolio includes the YE2 (IE2), YE3 (IE3), YEJ2 electromagnetic brake, and YVF2 variable frequency drive (VFD) series – all manufactured with advanced materials, F‑class insulation, and robust cast‑iron frames to ensure long service life, low noise, and minimal vibration.
Key Benefits Across All Series
Complies with GB18613 Level 3 and IEC 60034‑30 IE2 efficiency. Suitable for fans, pumps, compressors, machine tools, and general industrial machinery.
Upgraded design with higher efficiency and lower losses. Meets IE3 international standard. Ideal for continuous duty applications where energy cost reduction is critical.
Integrates a fail‑safe DC brake that engages on power loss, providing quick stopping (0.15‑0.45s no‑load). Widely used in conveyors, hoists, packaging, woodworking, and door operators.
Specially designed for inverter duty with forced ventilation (IC416) to maintain cooling at low speeds. Offers stepless speed regulation from 150 to 2750 rpm, ideal for textile, metallurgy, chemical, and pump/fan applications.
