Product Description:

The SE-B2.030.060-05.000 synchronous servo motor is manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It serves as a rotary actuator that converts electrical energy into controlled mechanical motion for positioning or speed-regulated axes in automated equipment. Using the IM B5 mounting interface, the motor can be flange-mounted to gearboxes, linear stages, or machine frames without extra brackets, which simplifies integration where space is limited.

The motor has a nominal speed of 6000 rpm and a static torque of 3.0 Nm, supporting high cycle rates in pick-and-place or spindle applications. Torque increases in proportion to phase current through a torque constant of 0.43 Nm/A; therefore, producing 3.0 Nm requires approximately 7 A. Continuous stall operation is governed by a standstill current of 7.5 A, while the inverter may reach 45 A during brief overloads. The back EMF rises with speed according to a voltage constant of 45 V/1000 rpm, which is useful when verifying DC bus margins. A 1.8 V/1000 rpm tacho output provides analog speed feedback. The stator has an inductance of 14.0 mH and a resistance of 2.25 Ω, allowing the drive to tune its current loops accurately.

Dynamic response is characterized by an electrical time constant of 6.1 ms and a mechanical time constant of 7.5 ms, so commanded torque changes translate into shaft speed adjustments with minimal delay. The rotor inertia of 0.60 × 10⁻³ kg·m² keeps stored kinetic energy low, allowing rapid reversals without placing excessive stress on the drivetrain. The motor has a thermal time constant of 19 min, which permits short overload intervals before winding temperatures approach their limit. Its shock resistance is rated at 6 g, supporting operation on mobile frames or tooling heads exposed to mechanical vibration. This resistance helps protect the motor during abrupt machine movements and other short-duration impacts within the rated limit.
