TE90 and TE150 series servo spindle and permanent magnet motors — selection guidance by speed and application
Copper-Rotor Servo Spindle
TE90 / TE150 series · 6,000–24,000 rpm
Why Copper Rotor?
Most high-speed spindle motors on the market use aluminum rotors to cut cost. Shangqing servo spindles emphasize copper rotors for efficiency, thermal performance, and continuous high-speed duty.
Shangqing Servo Spindle
Copper Rotor
- Higher conductivity, lower rotor copper losses
- Higher operating efficiency, less heat under the same load
- Better suited to long continuous high-speed runs
- More controllable temperature rise — supports insulation life
Common on the Market
Aluminum Rotor
- Lower cost; die-cast process is widely used
- Higher resistivity, relatively higher rotor losses
- Temperature rise more noticeable in long high-speed duty
- Cost-oriented standardized solutions
-
Copper Rotor Design
Shangqing servo spindles use copper rotors. Versus common aluminum rotors, rotor losses are lower — better suited to continuous high-speed duty.
-
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 help control temperature rise, extend service life, and improve electrical safety.
-
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.
