Product Description:

The SE-B2.020.060-10.037 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. In automated machinery, this motor supplies precisely regulated torque and speed so that positioning tables, pick-and-place axes, and similar drive systems track controller commands with minimal deviation. A tacho generator delivers 1.8 V per 1,000 rpm for use with legacy velocity feedback loops.

During continuous motion, the rotor reaches a nominal velocity of 6000 rpm, while a standstill torque of 2.0 Nm keeps loads stable at zero speed. Each ampere of phase current produces torque according to a torque constant of 0.40 Nm/A; this relationship supports current-loop tuning and drive sizing. Transient demands are supported by a peak current limit of 30 A, and the motor windings have a synchronous inductance of 20.8 mH, which helps limit current ripple at high switching frequencies. Electrical dynamics include a 10.2 ms electrical time constant, a 4.6 ms mechanical time constant, and a standstill current of 5.0 A. The windings have a resistance of 4.43 Ω, which affects voltage requirements and power losses during operation.

An IP67 housing protects the stator against dust ingress and temporary immersion, allowing installation outside sealed cabinets. The flange uses an IM B5 mounting arrangement, providing a centered spigot and threaded holes for alignment with gearboxes or machine frames. The plain shaft has no keyway, so couplings must clamp securely to its surface. The motor has a thermal time constant of 15 min, indicating how quickly its temperature approaches a steady level during load changes. It generates counter-electromotive force at a rate of 46 V/1000 rpm, which is relevant when calculating DC-bus margins during regenerative deceleration. Its rapid electrical and mechanical response supports high-speed motion where accurate torque regulation and short acceleration cycles are required.
