CM Synchronous Servomotors

  • Your benefits:
    • Reliable and economical
    • Particularly small mass moment of inertia
    • Large torque range
    • High overload capability
    • Low losses
    • Electronic nameplate for quick and simple startup
CM series

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.
