Product Description:

The 52.SM.200-34CJ is a synchronous servo motor manufactured by KEB for the SM Synchronous Servo Motors series. The unit converts electrical energy into precise mechanical rotation, allowing automation controllers to position loads accurately and regulate speed over a programmed motion profile. Typical applications include pick-and-place arms, feed rollers, and other motion axes where repeatability and fast response are required. A self-cooling housing dissipates heat without auxiliary fans, allowing the motor to operate in compact enclosures while maintaining suitable temperatures during continuous duty cycles.

The continuous performance range includes several electrical and mechanical ratings. A nominal mechanical output of 2.60 kW indicates the power available at the shaft under rated conditions. At that operating point, the rotor turns at 3000 rpm and produces a steady torque of 8.5 Nm, balancing speed and force for general-purpose machinery. The motor requires a line-to-line voltage of 330 V, while the phase windings draw a rated current of 6.0 A. These values support the selection of an inverter and cables that match the motor’s impedance and thermal limits. They also indicate the electrical capacity needed to reach full continuous output without derating.

For applications that demand higher holding force or frequent start-stop cycles, the motor develops a stall torque of 10.54 Nm, which helps resist load disturbances at low speed or standstill. The rotor inertia is 11.9 kg·cm², allowing responsive acceleration while accounting for the mechanical resistance to changes in rotational speed. Dynamic behavior is also influenced by a winding inductance of 11.5 mH, which filters current ripple and affects the response of the current control loop. The motor has a total mass of 9.8 kg, which must be considered when sizing mounting surfaces or gantry structures. Secure mounting helps prevent unwanted movement when the motor accelerates, decelerates, or operates against changing loads.
