Lift engine , Iran

Gearless elevator motors are permanent magnet synchronous motors PMSM. Their efficiency typically ranges from 94% to 96% at rated speed. Rotational speed is set between 100 to 250 RPM for standard applications. The motors rated torque varies from 500 to 5000 Newton meters. Winding insulation is often Class F with a 155°C thermal tolerance. Cooling systems use internal fans or dedicated liquid cooling. Motor nominal input is typically 380V AC, three-phase, 50Hz. Variable Voltage Variable Frequency VVVF drives reduce speed fluctuation below 0.5%.

The motor connects directly to the traction sheave. Its compact design occupies up to 40% less space than geared systems. Stator outer diameter ranges from 300 to 800 mm based on power. High-flux density permanent magnet technology improves energy efficiency by up to 30%. Real-time monitoring tracks temperature and vibration with 95% accuracy. Operational sound pressure level is below 55 dB at 1 meter. The design life exceeds 150,000 hours of continuous operation. This motor design eliminates the need for periodic greasing.You can order and buy Lift engine from Iran by contacting us through whatsaap and email.
