Product Description:

The SE-B5.320.030-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as a rotary actuator for CNC machines, packaging stations, and other automated axes where tight velocity and position control are required. When paired with a drive controller, the motor converts electrical command signals into mechanical motion that follows accurate motion profiles. This arrangement supports repeatable axis movement in applications that need stable speed regulation, responsive positioning, and smooth torque delivery across changing loads.

During continuous operation, the motor reaches a nominal speed of 2000 rpm, allowing controlled rotational rates for medium-torque axes. It has a torque constant of 1.11 Nm/A, so each ampere of phase current produces useful torque output. The back EMF is 118 V/1000 rpm, which the drive must accommodate during regeneration. Current rises to 63% of its final value in 20.4 ms, while the rotor reaches 63% of final speed in 2.4 ms. A 180 mm flange pilot centers the housing on machine frames, the Ø32 × 58 mm shaft transfers torque through keyed couplings, and the 10.0 mm² motor connection area works with windings that have 0.22 Ω resistance and 4.6 mH inductance to match inverter operation.

Rotor inertia is 13.6 x10⁻³ kgm², balancing quick indexing with load stability during speed changes and short move cycles. The complete assembly weighs 31 kg, adding mass that can help reduce vibration in the driven system. The housing has an IP65 rating, which blocks dust ingress and protects against water jets for installation outside control cabinets. An overall length of 345 mm helps the motor fit into space-limited machine layouts where flange size and axial clearance must both be considered. The 40-minute thermal time constant means winding temperature changes occur gradually during load changes, so brief overload periods do not cause an immediate temperature rise.
