The SKF Rotor Positioning Bearing is an integrated unit that combines a high performance magnetic impulse ring clamped to a high speed, high temperature bearing.
- Generates strong magnetic impulses that are related to the rotor angular position
- Robust under severe running conditions due to high magnetic field strength
- Helps reduce CO2 emissions and fuel consumption for stop-start systems
- Well suited for electric motor drive and control and stop-start systems
- Customizable to electric motor size and number of pole pairs
- Features accurate magnetic field with standard deviation < 8 Gauss
- Provides period accuracy < 0.5 degrees
- Magnetic ring has high positioning accuracy
- Includes innovative rubber material
- Operating temperature range of –40 C to 170 C
- Features high speed ability (shaft size dependent)
- Offers acceleration of 0 to 14,000 r/min in 1 second
- Vibration level up to 40 g
- Benefits include improved electric machine efficiency, optimized system noise and reliable performance over complete operating range
- Features extreme environmental resistance
