DS/CM series
|
|
SEW synchronous servomotors are ideal for highly dynamic applications. With three sizes and three lengths for each, the new CM motor series covers a torque range from 5 to 70 Nm (40 to 620 lb-in) static torque. This motor is equipped with high-energy NdFeB magnets and thus offers an extremely high overload support of 400% standstill current as a standard. The CM servomotor owes its compact design with very high power density to the new magnetic circuit layout.
