SD-B5 250.015-10.000

The Bosch Rexroth Indramat SD-B5 250.015-10.000 from the SD Magnet Motors series is a high-performance, inverter-operated permanent-field servomotor designed for precision motion control in industrial automation. This B5 design unit delivers a continuous Torque of 25 Nm and operates at a nominal Speed of 1500 rpm, making it ideally suited for applications requiring stable, repeatable torque and speed. As part of the Servodyn drive system, it supports electronic commutation and must be paired with a Bosch Rexroth inverter to ensure full compatibility and optimal dynamic response.

Incorporating robust technical features, the SD-B5 250.015-10.000 uses high-quality ball bearings at the flange end with a minimum service life of 20,000 operating hours, and it is rated to Protection Standard IP 54 for reliable operation in dusty or splashed environments. The motor’s cooling relies on natural convection and thermal radiation, so adequate heat dissipation is essential; in high-temperature conditions, a touch guard may be required due to potentially elevated surface temperatures. Internally, the unit integrates a brushless tacho and commutation sensor at the non-driving end, ensuring precise feedback without the need for a separate encoder. Key winding parameters include a torque constant of 1.94 Nm/A, a winding resistance of 1.26 Ω, and a winding inductance of 26.8 mH, all contributing to smooth current-to-torque conversion and predictable dynamic behavior.

Designed for flexible installation, the motor supports horizontal mounting in all orientations and vertical mounting in the IM V3 position, provided that fluid accumulation at the flange end plate is prevented. The shaft extension is threaded for safe fitting and removal of drive elements, such as clutch disks, belt pulleys, and gear wheels, but must never be struck or hammered to avoid rotor or bearing damage. With an admissible peak torque three times its rated torque, the SD-B5 250.015-10.000 exhibits high resistance to demagnetization and vibration quality conforming to Level N, ensuring durability in demanding duty cycles. From enhanced compatibility and robust protection to reliable thermal management and service life, this servomotor delivers significant benefits in performance, efficiency, and uptime for industrial applications.
