Product Description:
The 52.SM.200.34B0 is a synchronous servo motor manufactured by KEB for the SM Synchronous Servo Motors series. It provides closed-loop rotary actuation for tooling, conveying, and indexing axes in automated equipment by converting drive current into regulated torque and speed. The housing uses the long-frame style commonly found on three-phase asynchronous motors, providing additional magnetic length without increasing the flange diameter. Its self-cooled frame supports operation without an external fan or a separate source of forced airflow.
The motor provides a continuous mechanical output of 2.60 kW at a rated shaft speed of 3000 rpm. It produces a rated torque of 8.5 Nm while drawing 6.9 A from a 330 V supply for the 400 V class or a 560 V DC supply. The IP54 protection level guards the stator against dust ingress and water spray. A peak-to-rated torque ratio of 5.0 supports short periods of increased torque, while a rotor inertia of 11.9 kg cm² affects acceleration and deceleration response. The rated winding has an inductance of 11.5 mH and a resistance of 1.7 Ω.
During transient operation, the servo withstands a stall torque of 10.54 Nm, and its no-load speed can reach 3600 rpm. Rotor position is reported by a two-pole SSBH-15-E-5 resolver, which provides feedback to the connected servo drive. The back-EMF constant of 130 V/1000 rpm supports drive selection and current-loop adjustment. The motor mounts through a B5 IFT5-compatible flange, and a shaft with a feather key transmits torque to the connected machine. Circuit protection is provided by a 20 A mains fuse. The unit has frame size 52 and weighs 9.8 kg without a brake. Its bearings support a lateral load of 730 N and an axial load of 210 N. The motor is supplied without a holding brake, so an external mechanism or drive-applied torque must secure stationary loads when necessary.
