Product Features
Review key advantages before selecting a power rating
-
Copper Rotor Design
Shangqing copper-rotor servo spindle motors use copper rotors. Versus standard aluminum rotors, losses are lower and temperature rise is easier to control — more stable for long continuous high-speed duty. Actual performance still depends on load, cooling, and drive conditions.
-
Wide Constant-Power Range
Above rated frequency, output power is maintained — delivering wide-range constant-power characteristics.
-
Stable Constant Torque at Low Speed
Below rated frequency, the magnetic field remains stable and linear, maintaining constant torque output.
-
Enhanced Winding & Insulation
Special winding design and insulation grade — coil insulation withstands high-frequency inverter waveforms without breakdown.
-
High-Grade Silicon Steel
Premium electrical steel maintains linear control within the operating range, delivering excellent servo performance.
-
Lower Temperature Rise
Copper’s higher conductivity and lower rotor losses make temperature rise easier to control, supporting insulation and bearing life and improving running stability.
-
High Power Density
Precision-engineered design minimizes size while maximizing efficiency for a higher power-to-volume ratio.
-
Optimized Rotor Inertia
Well-designed rotor inertia delivers highly responsive performance under servo drive control.
