SR Industrial Motors
SR
Motor
- Precise speed control
- Higher speed than VFD motors
- High start torque
- High full-load torque
- Low inertia rotor
- Minimal losses in rotor
- Bi-directional regenerative braking
SR Rotor
- No copper
- No coils
- No commutator
- No electrical maintenance
SR Stator
- Simple rugged construction
- No magnets
- No interphase shorts
- Short coil overhang
Industrial SR Motor Sizes
30kW, 45kW, 50kW, 55kW, 75kW,
90kW, 110kW, 135kW, 185kW, 320kW
| Comparison of a 7.5kW SR Motor and a VFD Motor: |
 |
| Constant 50Nm torque to 1500 RPM.
Constant 7.5kW power thereafter. |
Special Application SR Motors
- 30,000 RPM capable fractional HP
- 1000% of full load torque at start
- Closed circuit cooled
- Severe traction service
