SEW-EURODRIVE is setting a new standard for efficiency with the launch of the DR2C motor, an IE5 ultra-premium efficiency ...

giving the rotor a little boost. The difference here is that rather than low-friction sapphire bearings, this motor uses zero-friction magnetic levitation using pyrolyzed graphite discs.

“Pancake” style axial-flux motors sandwich a disclike permanent-magnet rotor between stator discs. Orbis’ version is tunable in two ways: For the strongest, skinniest setup ...

SEW-EURODRIVE’s DR2C motor series utilizes Interior Permanent Magnet technology, which integrates permanent magnets within the rotor instead of surface-mounted ones.

These stator teeth are used for the coils, which align with either a permanent magnet ring, a soft iron core or both on the rotor. Much like with other electric motors the stator coils rotate the ...
