Product Description:

The 01.SM.000-3200 is a synchronous servo motor produced by KEB and included in the SM Synchronous Servo Motors series. As a closed-loop actuator, the unit converts electrical energy into controlled rotary motion so automated machinery can position loads accurately and repeatably on assembly, packaging, or conveying lines. It interfaces with a matched drive to supply commanded torque over a wide operating range while maintaining feedback-regulated speed during normal machine operation.

Its continuous operating point uses a rated speed of 3000 rpm and a rated torque of 0.8 Nm, meaning the shaft can deliver that mechanical output without exceeding thermal limits. At that load, the motor produces 0.53 kW of mechanical power, making it suitable for indexing tables or small tool drives. Electrical loading for this point requires a phase current of 1.2 A when the stator is excited at 150 Hz. That frequency, set by the inverter, matches the motor’s magnetic design so the electrical angle stays synchronized with the rotor and yields the stated speed. For static holding or low-speed positioning, the standstill current rises to 1.4 A so the magnetic field can generate the required torque without rotor movement.

These electromagnetic constants help size the drive electronics and tune control loops for stable motion. The back-electromotive-force constant is 37 Vpk/1000 rpm; this value indicates the peak line-to-line voltage returned by the motor per thousand revolutions and helps establish DC-bus margin. Stator impedance is characterized by a winding inductance of 25.4 mH and a winding resistance of 21.6 ohm. Higher inductance smooths current ripple, while the resistance sets copper losses, so together they affect temperature rise during rapid acceleration, regeneration, and frequent direction reversals that are typical in servo positioning tasks.
