Product Description:

The SE-B3.075.030-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. It serves as a compact rotary actuator for industrial automation tasks that require repeatable velocity and position control. The motor mounts through a 116 mm flange and uses a 19 × 40 mm keyed shaft, providing a standardized connection for gearheads, pulleys, or direct-coupled loads. Its compact layout is well suited to machinery where accurate motion must be delivered within limited installation space.

The unit reaches a nominal speed of 3000 rpm while delivering a static torque of 9.3 Nm at standstill. A torque constant of 0.98 Nm/A relates commanded current to output torque, and an electrical time constant of 10.2 ms describes current buildup in the windings for responsive control loops. Short-term overload demand can rise to a peak phase current of 57 A, while continuous operation at standstill draws 9.5 A. Additional electrical data includes a voltage constant of 113 V/1000 rpm, a tachogenerator output of 2.7 V/1000 rpm within ±5%, a mechanical time constant of 3.3 ms, and a 30 ms ramp-up period for commanded acceleration.

The rotor moment of inertia is 1.66 × 10⁻³ kg·m², which supports quick reversals without excessive drive energy. A winding inductance of 21 mH helps smooth current ripple, and the thermal time constant of 32 min allows the motor to absorb intermittent overloads before heat fully builds in the housing. The winding resistance is 2.1 ohms under the stated conditions, and the motor can be used in packaging equipment, handling systems, and indexing applications that involve repeated start-stop motion. These operating values make the unit suitable for precise axis control where stable response and predictable thermal behavior are required.
