Product Description:

The SE-B4.130.030-14.150 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as an electromechanical actuator for industrial automation systems that require precise velocity and position control. The motor converts regulated drive current into accurately commanded rotary motion for packaging lines, material-handling stages, and machine-tool axes.

The unit has a rated shaft speed of 3000 rpm under nominal electrical conditions. During zero-speed operation, the energized windings allow the rotor to supply a static torque of 13 Nm while the shaft remains motionless. The motor has a torque constant of 0.80 Nm/A, providing a clear scaling factor between drive current and generated torque for current-loop control. Short bursts of up to 84 A are permitted as peak current, enabling rapid acceleration or deceleration of connected loads without magnetic saturation. An electrical time constant of 9.7 ms indicates how quickly current rises in the stator, allowing the drive to respond promptly to changing torque commands.

For applications that require the shaft to remain locked after drive power is removed, the integrated brake provides a holding torque of 18 Nm and operates from a 24 V DC ±10% supply. The brake coil has a nominal current draw of 1.0 A. Continuous standstill operation is supported at 15 A, balancing copper loss against thermal limits associated with the 9.7 mH winding inductance and 0.96 Ω resistance. The motor body has an IP67 protection rating, which prevents dust ingress and protects the housing against temporary immersion. Its mechanical interface includes a 142 mm flange and a shaft measuring 24 mm in diameter by 50 mm in length.
