Product Description:

The SE-B5.320.030-00.016 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. Designed for closed-loop drive systems, the unit converts commanded current into proportional shaft torque for indexing tables, gantry axes, and similar automation duties. Its sealed construction, feedback-ready flange, and metric shaft allow direct coupling to gear stages or loads while maintaining repeatable speed control.

The motor produces a continuous static torque of 38 Nm, enabling stable holding or slow-speed operation without overheating. Under rated excitation, it reaches a nominal speed of 3000 rpm, which is the baseline velocity used for drive sizing and gear selection. Its torque constant is 1.11 Nm/A, so every ampere of phase current delivers a predictable amount of torque. The motor can accept a peak current of up to 256 A for rapid acceleration, while the rotor inertia is held to 13.6 × 10⁻³ kg·m² so speed changes occur without placing excessive load on the controller. Additional parameters include a standstill current of 34 A at M0, a mechanical time constant of 2.4 ms, a ramp-up time of 54 ms, and a winding resistance of 0.22 Ω at 20 °C.

The enclosure carries a protection rating of IP65, which blocks dust ingress and low-pressure water jets when the shaft seal is used. The motor has an electrical time constant of 20.4 ms and a winding inductance of 4.6 mH, which shapes current ripple during pulse-width modulation drive operation. For short bursts, the motor can deliver a maximum torque of 92 Nm, supporting high-load starts or quick positioning moves. The voltage constant is 118 V/1000 rpm at 40 °C. A thermal time constant of 40 minutes permits intermittent overloads while keeping the winding temperature within the insulation limits.
