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. The DS series, with its three lengths, covers the lower 1 to 4 Nm (9 to 40 lb-in) static torque range. The acceleration torques of the motors are three to four times the static torque for all sizes. All motors come equipped with standard thermal motor protection and resolver feedback for motor control.
