Y3Y3 Series Low-Voltage High-Power Three-Phase Induction Motor (H355–450)
Y3 Low-Voltage High-Power Motor HUALI
Y3 in its large-frame version covers low-voltage motors of 200–900 kW with shaft heights 355–450 mm, 2–10 poles, 380/660 V, 50 Hz; catalogue types 355LX1…450LX4. IE1 efficiency class, tabulated efficiency 94.7–96.5 %, breakdown torque ratio 2.5. TEFC IC411, IP54/IP55, class F or H insulation, IMB3 mounting (V1 on request). The series fills the gap between standard YE3 (up to 375 kW) and high-voltage YKK where only a 0.4/0.66 kV network is available: crushers, mills, large pumps and fans. Reference: Y3-400LX-2-630 and Y3-355LX-4/6 at Jinan Steel (Minyuan).
