Product Description:

The SE-B3.033.030-00.000 synchronous servo motor is produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Serving as the rotary actuator in closed-loop drive systems, the unit pairs with digital drives to deliver accurate motion in pick-and-place heads, form-fill-seal stations, and other industrial automation tasks that demand repeatable positioning and speed regulation. Its operating profile suits applications that need controlled acceleration, stable running speed, and reliable position feedback during repeated machine cycles.

A nominal speed of 3000 rpm gives the shaft speed at rated load, while a static holding torque of 4.2 Nm shows the torque available at standstill. During start-up, the drive can deliver a peak phase current of 24 A; in normal parking conditions, it draws 4.0 A. Combined with a winding resistance of 7.9 Ohm and an inductance of 60 mH, these values shape the motor’s electrical response together with a torque constant of 1.02 Nm/A. The voltage constant is 112 V/1000 rpm, so at nominal speed the controller must supply about 336 V to maintain flux. A mechanical time constant of 5.8 ms shows how quickly the rotor accelerates, and the 225 mm overall length supports installation where axial space is limited.

A maximum torque of 9.1 Nm gives the axis short-term capacity to overcome friction peaks and brief load changes. The electrical time constant of 7.6 ms shows how quickly armature current rises, and when combined with the rotor inertia of 0.81×10⁻³ kg·m², it supports close tracking of fast command changes. Heat generated by copper and iron losses is averaged over a thermal time constant of 19 min, which allows intermittent loads to be absorbed before temperature limits are approached. The 8.1 kg mass supports stable mounting and helps reduce the effect of vibration during operation.
