Product Description:
The SE-B4.130.030-04.101 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. As a servo actuator, it is used in machinery that requires repeatable positioning and stable speed control in automated lines, presses, and handling modules. The housing is arranged for flange installation, and the shaft projects from the drive end so standard couplings can be fitted without extra adapters. This layout supports direct motor-to-load connections in compact machine sections where accurate alignment is important.
The motor has a holding capability of 18 Nm and a static stall torque of 13 Nm. During continuous operation, it reaches 3000 rpm, which provides the base speed used for motor and gearbox matching. The mounting interface follows the IM B5 pattern, so the motor is face-mounted by a pilot and bolt circle rather than by foot mounts. An allowable ambient range of 0 to 40 °C keeps operation within the intended thermal range. The front face carries a centering hole to DIN 332-DS M8, and the drive end includes an oil-tight sealing element to help prevent lubricant migration. An O-ring seat diameter of 125.4 h9 mm with size 124-3 mm provides axial sealing against the machine wall, and the connector area accepts power conductors up to 2.5 mm².
The motor includes an electrically released brake supplied at 24 VDC ±10%, and the brake coil draws 1.0 A during release. The brake assembly adds 1.7 kg to the overall mass and contributes a polar inertia of 0.90 × 10−3 kg·m², which should be considered in axis tuning and acceleration response. The shaft is machined to Ø24 × 50 mm for use with keyed or shrink-fit hubs. The specified connection cross-section supports current flow without excessive resistive loss.
