Product Description:

The SE-B5.250.030-00.027 is built by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. This brushless servomotor supplies commanded torque and velocity to automated axes in assembly stations, filling machines, and similar motion platforms. Electronic commutation and a rare-earth field rotor let the unit respond quickly to control signals while avoiding brush maintenance common in older designs. That makes it suitable for indexing tables, synchronized conveyors, and other axes where motion must track a commanded profile without excessive lag.

The motor reaches a nominal speed of 3000 rpm, making it suitable for high-throughput applications that still demand smooth low-speed control. Heat produced in the stator is removed by natural convection, so no forced air or liquid circuit is required. The mechanical interface uses IM B5 flange mounting, and power conductors are routed through a terminal box that accepts armored machine wiring. Speed feedback is provided by a brushless tachogenerator, and the dedicated socket on the housing gives the drive direct access to that signal. The feedback signal supports stable speed regulation, and a balance quality code N rotor helps limit residual vibration when the motor is coupled to precision gear stages or belt drives.

Output torque is transmitted through a shaft with a keyway and feather key, giving positive engagement with couplings and pulleys. The housing resists impacts up to 6 g, helping the unit tolerate transport shocks or short mechanical disturbances during operation. High-energy rare-earth magnets in the rotor increase torque density without enlarging the frame. A winding thermistor is embedded in the coil pack so the drive can monitor winding temperature and reduce current before overheating occurs. The sensor output can also be used to trigger a protective shutdown if winding temperature continues to rise.
