Lift engine , Iran

Modern elevator traction machines are Permanent Magnet Synchronous Motors PMSM. They achieve over 95% efficiency across 25% to 100% load ranges. Standard speeds are 1 to 4 meters per second with ±3 mm positioning accuracy. Rated motor power varies from 10 to 50 kW for mid-rise buildings. Winding insulation typically meets Class H thermal rating 180°C. Starting current is limited to less than 1.5 times the rated current. Forced air cooling with ECM fans maintains winding temperature below 120°C. IGBT inverters with Space Vector PWM SVPWM minimize harmonic distortion.

The gearless design directly couples to the traction sheave, reducing energy loss below 3%. Continuous torque output reaches 3000 Nm with 200% momentary overload capacity. Sound pressure level in the machine room is below 55 dBA. High-resolution encoders with 614,400 pulses per revolution enable precise speed control. The motor frame is constructed from 316 stainless steel with powder epoxy coating. A CAN bus monitoring system tracks bearing health and magnetic flux. The designed operational lifespan typically exceeds 200,000 complete duty cycles.You can order and buy Lift engine from Iran by contacting us through whatsaap and email.
