Product Description:

The C3.SM.002-64DH is a synchronous servo motor built by KEB and assigned to the SM Synchronous Servo Motors series. Within an automation cell, it operates as the primary mechanical actuator, taking drive signals and delivering controlled torque to indexing tables, conveyors, and gantry axes. Its permanent-magnet rotor and resolver feedback enable high positioning accuracy, making the unit suitable for continuous-duty motion profiles found in material-handling and assembly equipment.

The motor is rated for continuous operation under duty type S1, and its electrical design supports a top shaft velocity of 9000 rpm. At that speed, the back EMF rises in proportion to the voltage constant of 103.24 Vpk/1000 rpm, a value the drive must match to keep the control loop stable. Normal running draws 4.75 A, while the electromagnetic structure can hold a static load with a stall torque of 5.65 Nm. The phase winding resistance is 2.4 Ohm, so thermal models inside the inverter can predict temperature rise accurately. The neodymium-iron-boron magnets sustain flux density even at elevated temperatures, supporting this continuous rating.

Transient demands are handled by a peak torque of 29.25 Nm and a momentary current ceiling of 31.0 A, giving adequate margin for acceleration events. The stator coils have a winding inductance of 15.8 mH, which filters current ripple and influences the drive's PWM frequency selection. Four magnetic pole pairs, shown by the count of 4, yield electrical cycles that align with common servo controllers. The unit connects through an angular flange socket, size 1, which simplifies cabling in tight enclosures. A KTY 84-130 sensor embedded in the windings provides temperature feedback, while the current at stall torque offers another reference point for sizing the power module and selecting protective fuses.
