CM Synchronous Servomotors SEW-EURODRIVE
SEW synchronous servomotors are ideal for highly dynamic applications. The CM motor series is available in three sizes with three lengths each and covers a standstill torque range from 5 Nm to 68 Nm. This motor comes equipped with high-energy NdFeB magnets and offers a very high overload behavior of 400% standstill current as standard. The CM servomotor owes its compact design with very high power density to the new magnetic circuit design.
Features
- Reliable and economical
- Particularly small mass moment of inertia
- Large torque range
- High overload capability
- Low losses
- Electronic nameplate for quick and simple startup
