Product Description:

The 33.SM.201-34BJ is a three-phase synchronous servo motor produced by KEB within the SM Synchronous Servo Motors series. The unit is intended for precision positioning and speed control duties in automated machinery, where closed-loop feedback from its Heidenhain EQI 1329 multiturn encoder allows the attached drive to maintain accurate shaft orientation under varying load. A turnable angular connector lets the cabling exit in the preferred direction, which helps routing when space around the motor is limited. This makes the motor suitable for repeatable motion on packaging equipment, indexing systems, and other controlled axes.

This model delivers a rated mechanical output of 680 W at a nominal shaft speed of 3000 RPM. Continuous operation at that speed corresponds to a rated torque of 2.15 Nm, while the design can reach a maximum torque of 10 Nm during brief acceleration or disturbance events. That output level suits compact servo axes that need steady speed with short peak-demand events. The housing length is 222 mm, and the motor uses a B5 flange for alignment to standard gearbox or machine faces. Cooling is self-contained, so no external blower is required, and the IP64-rated shaft gland helps limit particle and liquid ingress at the output end.

The enclosure has a protection class of IP65, which helps prevent dust entry and resists low-pressure water jets during washdown. Starting from standstill, the electromagnetic design supplies a stall torque of 2.5 Nm, providing holding force when current is applied and rotation is inhibited. The windings are designed for a voltage class of 330 V, and the back EMF follows a voltage constant of 70.7 V/1000 RPM for drive matching. Mechanical mounting uses the B5 pattern only, so the motor is intended for face-mount installation rather than foot mounting.
