Product Description:
The SE-B3.033.030-10.000 belongs to the SE Synchronous Servo Motors series produced by Bosch Rexroth Indramat. It is a compact brushless motor intended for closed-loop motion axes in automated packaging, pick-and-place, and tooling machines. Within these systems, the motor converts electrical drive output into mechanical rotation so position and velocity can be regulated by a controller. A cylindrical housing with a B5 flange enables direct mounting to gearboxes or load shafts, while the integrated tachogenerator supplies speed feedback to the drive for stable control. Its brushless design also reduces routine wear associated with contact-based commutation components.
During continuous operation, the rotor can reach a nominal speed of 3000 rpm, allowing standard servo drives to synchronize motion with 50 Hz or 60 Hz machine cycles. At standstill, the phase windings draw a peak current of 4.0 A, which must be considered when the axis holds position for extended periods. Short bursts of acceleration are supported by a maximum torque of 9.1 Nm under sm 5/10 duty, while regenerated energy is dissipated through a plug-in braking resistor rated at 1.0 Ω. The built-in Hall sensor electronics and tachogenerator are powered from a symmetrical supply of ±15 V DC furnished by the controller. This arrangement supports stable feedback processing during rapid speed changes and repeated indexing moves.
The static holding capability is 4.2 Nm, so clamped loads remain steady without relying on an external brake. Acoustic emissions do not exceed 58 dB(A), which helps when the motor is installed near operator-access areas. Mechanical resilience is confirmed by shock resistance up to 6 g, and the overall length is limited to 225 mm, simplifying enclosure layout in compact equipment. Additional characteristics include an 8.1 kg mass, an Ø19 × 40 mm plain shaft without a keyway, a 2.5 mm² conductor cross-section, and IM B5 flange mounting. These features support installation in machines that need compact servo placement and direct coupling to standard drivetrain components.
