Magnetizing coils for Rotors
Magnetizing col for rotors are always suited to the specific rotor.
No of poles, diameter, skew angle and sometimes length of the rotor
are limitations which do not allow general rotor magnetziing coils.
- Iron coils for big poles
- Air coils for small poles and axial rotors
- air cooled / Water cooled
We optimize for:
- Minimum cogging by skewed magnetization
- Minimum cogging by shaping of the field on magnet surface
- Minimim pole transition
