Product Description:
The C2.SM.000-3400 is a synchronous servo motor manufactured by KEB for the SM Synchronous Servo Motors series. The unit is designed for closed-loop axis control in automated assembly, packaging, and material-handling equipment, where it converts electrical energy into controlled shaft motion with high positional accuracy. It features permanent-magnet excitation for high torque density in confined spaces. When paired with a KEB servo inverter, it supports selectable speed and torque profiles for different machine cycles. Its compact format suits machines where mounting space is limited but accurate motion control is still required.
Under nominal conditions, the motor operates from a 400 V three-phase supply and draws a rated current of 1.8 A to deliver 0.75 kW of mechanical power. At the corresponding 3000 rpm rated speed, it produces 2.4 Nm of continuous torque. Stall torque reaches 2.7 Nm with a constant stall current of 1.9 A. The windings have a resistance of 13.1 Ω and an inductance of 34.4 mH, which affect current response and drive tuning during changing loads. Peak capability reaches 12.2 Nm at 2500 rpm, and the no-load shaft can accelerate to 4150 rpm for short, fast indexing moves. Those electrical values help describe how the motor responds to demand changes across its operating range.
Dynamic response is supported by a 2.7 kgcm² rotor inertia that permits fast acceleration without excessive drive current. The motor has a mass of 3.9 kg, which helps keep the axis assembly compact while still providing useful torque output. During brief overloads, the controller can supply a 9.4 A peak current. The electromagnetic design converts that current into transient torque in proportion to the 111.0 V/1000 rpm voltage constant, which helps the drive account for generated back EMF as speed rises. This combination is useful on short-cycle axes that start, stop, and reverse direction repeatedly.
