Motor Magnets, Arc/Segment Magnets
for Electric Motors, PM Motors and Generators |
| ChenYang Technologies GmbH & Co. KG supplies all kinds of motor magnets (NdFeB, Hard Ferrite, bonded NdFeB and Alnico magnets) for specified
applications to different electric motors, PM motors and generators in the electrical engineering
and electric vehicles etc. These magnets can be made with high iHc materials to match special motor
applications. They are consistency for torque performance and ground to meet high precision
and concentric requirements. The following table help you find the optimal magnet material for your
motor magnets. |
