Key features

High Efficiency & Energy Saving: Saves up to 30% energy compared to induction motors; operates efficiently across 20%-110% load range.

Long Bearing Life: L10 life up to 100,000 hours (over 10 years) with grease nipples for easy re-lubrication.

High-Performance Magnets: Uses NdFeB magnets 18x stronger than ferrite, coated with epoxy for superior corrosion resistance.

Stable Synchronous Speed: Rotor speed synchronizes with magnetic field, eliminating slip and unaffected by voltage fluctuations.

Integrated Thermal Protection: Embedded PTC thermistors protect against overheating, phase loss, overload, and voltage issues.

Low Operating Current: High power factor reduces stator current by 15%-30%, lowering cable transmission losses.

Constant Torque Range: Delivers constant torque across broad speed range without forced ventilation or encoder.

CE Certified Quality: Meets CE certification standards for safety and performance in industrial applications.
