Permanent Magnet Rotors
Both small electric rotors for e.g. servo steering and larger rotors for e.g. electric vehicle (EV) drives are measured with Magcam’s Rotor or Combi Scanner, providing high speed measurements of the radial, tangential and axial field distribution on the rotor mantle.
Magnet quality issues include:
- Pole angle deviations
- Skewing angle deviations
- Cogging torque
- Pole peak inhomogeneity
- Noise problems (harmonics)
- Micro cracks
Analysis possibilities include:
- Radial/tangential/axial (3D) field distribution
- Pole peak detection and analysis
- Zero crossing detection
- Pole angle measurement
- Pole skewing angle measurement
- Fourier harmonics analysis (for e.g. noise problems)
- Cogging torque analysis
- Crack detection
