Product Description:

The SE-B5.320.030-00.036 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. It is intended for industrial automation tasks where a compact rotary actuator must deliver finely regulated torque and velocity through a closed-loop drive controller. By converting drive current into proportional mechanical output, the motor positions loads quickly and maintains accuracy in pick-and-place heads, linear stages, and indexing tables.

The electrical time constant is 2.4 ms, allowing current to rise rapidly when the drive issues a torque command. The mechanical time constant of 20.4 ms indicates how quickly the rotor reaches a new speed after the electromagnetic field is established. A torque constant of 1.11 Nm/A translates stator current directly into shaft torque, while the back-EMF slope of 118 V/1000 rpm supports drive voltage selection. The motor’s winding inductance of 4.6 mH and resistance of 0.22 Ω influence current-loop bandwidth and heat dissipation. Power and feedback conductors terminate on a connection area with a cross-section of 10.0 mm² to accommodate high peak currents. Motion is transmitted through a 32 mm shaft that extends 58 mm beyond the bearing set, providing sufficient length for coupling installation.

A centering seat of 142 mm and a bolt-circle flange diameter of 180 mm support alignment with common gearboxes and machine frames. The laminated stator stack is 345 mm long, and the complete assembly weighs 31 kg. With a rotor inertia of 13.6 × 10⁻³ kg·m², the axis balances rapid acceleration with load stability. The keyed interface measures 10 × 8 × 50 mm and prevents the coupled component from slipping under peak torque. Thermal modeling uses a 40 min time constant to predict winding temperature during cyclic duty profiles.
