Product Description:

The SE-B2.020.030-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat in the SE Synchronous Servo Motors series. Designed for closed-loop industrial automation axes, the unit converts drive current into controlled rotary motion. It is used for positioning, tracking, or speed control tasks on packaging equipment, handling robots, and similar machinery, and its synchronous design supports precise speed regulation when paired with a compatible servo drive.

At its operating point, the motor develops a continuous static torque of 2.9 Nm while maintaining a rated shaft speed of 3000 rpm. That output is supported by a standstill current of 2.7 A and a torque constant of 1.10 Nm/A, meaning torque rises in direct proportion to commanded current. The internal winding generates a back EMF of 114 V/1000 rpm, which is important for drive sizing and voltage matching. Current rises to its target value within the electrical time constant of 5.0 ms, and speed responds within the mechanical time constant of 4.8 ms, which helps the motor react quickly to command changes. Copper loss is influenced by a phase resistance of 14.7 ohms, and this electrical behavior supports stable current control during dynamic operation.

The housing carries a square flange of 100 mm and weighs 6.5 kg, allowing direct mounting to medium-frame gearheads or machine plates. Rotor inertia is 0.44 x 10^-3 kgm², so the motor does not place an excessive acceleration demand on the drive during frequent start and stop cycles. Stator coils have an inductance of 76 mH, which helps smooth current transitions during high-resolution torque control. Heat absorbed during intermittent overload dissipates over a thermal time constant of 17 minutes. The smooth Ø14 × 30 mm shaft is supplied without a keyway to suit clamp couplings and help reduce imbalance during rotation.
