Product Description:
The 52.SM.201-34CJ is a synchronous servo motor produced by KEB as part of the SM Synchronous Servo Motors series. Designed for industrial automation tasks, the unit converts drive-controller commands into precisely regulated shaft rotation, allowing coordinated motion in indexing tables, gantries, and packaging axes. Its feedback-ready construction integrates easily with closed-loop systems where speed accuracy and repeatable torque delivery are mandatory. This makes it suitable for axes that need stable response during starts, stops, and frequent position corrections under changing process loads.
During continuous operation, the motor is rated for a mechanical output of 2.60 kW. At this operating point, it runs at 3000 rpm and produces 8.5 Nm of torque with a phase current of 6.0 A from a 330 V DC bus. The 1.7 Ω winding resistance contributes to copper losses, and the 11.5 mH inductance helps limit current ripple in the drive inverter. This combination supports smooth current control and predictable speed response during repeated motion cycles. Rotor inertia is 11.9 kg cm², which supports quick acceleration without compromising stability. The bare frame weighs 9.8 kg, which helps keep mounting loads manageable, and the electromagnetic circuit remains within thermal limits for sustained operation without derating.
Beyond its nominal values, the 52.SM.201-34CJ can withstand a stall torque of 10.54 Nm while drawing 6.9 A. Protection against load drift is provided by an integrated holding brake that delivers 18 Nm; the brake coil operates at 24 V and draws 1.0 A. The brake helps keep the shaft from moving when power to the motion axis is removed. The brake's reflected inertia of 16,600 kg cm² must be added to the rotor inertia during dynamic calculations. A back electromotive force constant of 130.0 V/1000 rpm helps the drive predict generated voltage during high-speed deceleration and supports regenerative handling. These values help match the motor with a drive that can supply the necessary current and absorb mechanical energy during rapid indexing.
