Real Permanent Magnet SYNCHRONOUS Motor
Is your motor a real Synchronous Motor?
those with incremental encoders built in are actually NOT real Synchronous Motor!
We re-define PM Synchronous Motor during our motor production,
We synchronize home position of Encoder,home position of motor and home position of Controller,
We also synchronize performance of material,home position and output sine wave.
Minimum Zero Point Error (mechanical angle and electronic angle): ≤0.3°
Position Synchronized Performance:≥98%
Reluctance Resolver Built in motor as absolute encoder
Yuli PMSM use High Performance Material
YULI PMSM Winding material:100% red copper
Yuli PMSM Hairpin winding
Lamination: AHV series silicone steel
Permanent Magnet: UH series, 180°C no degausing
SKF high performance bearings
