Dynamic performance, precision, adaptability, and long service life are the key advantages of the new DS/CM line of synchronous servomotors, according to manufacturer SEW-Eurodrive. The servomotors provide an economical solution for highly dynamic applications like material handling, packaging, and crane and hoist control. They are available in three sizes, with three different lengths available for each size, and are UL and CSA approved. The servomotor series covers a wide range of standstill torques, from 1 Nm to 68 Nm, with peak performance ratings of up to 238 Nm. High overload capacity provides solutions for most power requirements. The company says these motors come in a sturdy housing with built-in convection cooling, assuring reliable performance, extremely quiet operation, and exceptional service life. The DS/CM series features modular design, allowing configurations to exactly match application requirements. This allows them to be mounted directly on a machine or integrated with the gear unit. Gear units in standard and reduced backlash designs can be installed, as well as planetary and angular servo gear units that mount directly on the motor without using an adapter.

The new servomotors are available with 24 V holding brakes for the DS series or powerful servo brakes for the CM series. The high torque of the optional working brake for the CM series provides an optimum solution for hoist applications.

The acceleration torque is three to four times the static torque for all sizes. The CM motor series, which covers a torque range between 5 and 68 Nm has high-energy magnets that deliver a high overload capacity of 400% standstill current as standard. Modern magnetic circuit technology assures high rotational accuracy and low cogging. All DS/CM servomotors are equipped with standard thermal motor protection and resolver feedback for motor control. www.seweurodrive.com SEW-Eurodrive
