Product Description:

The 63.SM.201-34B0 is a synchronous servo motor manufactured by KEB and offered as part of the SM Synchronous Servo Motors series. It is intended for integration into industrial automation systems that require accurate rotary positioning and speed control. A two-pole resolver mounted on the shaft reports the rotor angle to the drive in real time, enabling precise velocity and torque control. This feedback supports controlled motion in pick-and-place modules, feed rollers, indexing tables, and other automated equipment.

During short acceleration bursts, the motor can draw a maximum phase current of 74.8 A, allowing the electromagnetic circuit to produce up to 66 Nm of peak torque for overcoming inertia or friction. During continuous operation, the winding carries 11.8 A and provides a mechanical output of 5.03 kW when the shaft turns at its rated speed of 3000 rpm. These values establish the steady operating range used to select suitable gearboxes, couplings, and supply cabling. The overall length of 289 mm allows the frame to fit inside compact machine spaces while maintaining sufficient magnetic stack depth for the stated power density.

At standstill, the electromagnetic circuit sustains 22 Nm without exceeding its thermal limit, and the resolver feedback allows the controller to apply this torque accurately when holding loads in position. A voltage constant of 125.9 V/1000 rpm indicates the back electromotive force generated in relation to shaft speed, helping the inverter maintain suitable DC-link voltage margins. Dynamic response is influenced by the stator inductance of 9.2 mH, which moderates the current rise time. The winding resistance is 0.74 Ω, which affects copper losses during continuous duty. A stall current of 15.0 A also contributes to drive tuning, thermal management, and selection of allowable cycle rates for demanding automation tasks.
