SD-B4.070.030-15.000

The Bosch Rexroth Indramat SD-B4.070.030-15.000 from the SD Magnet Motors series is a versatile permanent-field servomotor designed for industrial mechanical engineering applications. Engineered to operate with TA or TC series inverters, this unit features an integrated brushless tacho and commutation sensor to deliver precise velocity feedback and rotor position detection. With a nominal speed of 3000 rpm and embedded permanent magnets constructed from Ferrite, the motor offers reliable performance and maintenance-free operation when used as intended. Its standard construction prohibits structural modifications, ensuring stable, long-term service life.

Measuring 366 mm in total length, the SD-B4.070.030-15.000 is built with robust fixed ball bearings at the driving end for secure mounting and enhanced load handling. The motor housing carries a type label with key technical details and offers an IP 54 protection rating per DIN 40 050/40 053 standards, making it resistant to water splashes common in factory environments. Designed for electronic commutation and free of a separate encoder, the unit supports peak inverter currents of 10 A and 20 A, ensuring compatibility with a wide range of drive electronics.

The servomotor can be mounted horizontally or vertically (shaft down) and requires adequate heat dissipation provisions to maintain optimal operating temperature. Two plug connectors are provided for inverter integration, and mating connectors—either right-angle or straight—must be procured separately. With standard customization and a maintenance-free design, it minimizes downtime and reduces overall lifecycle costs. The SD-B4.070.030-15.000’s rugged construction, precision feedback, and compliance with industrial protection standards make it an ideal choice for demanding servo drive applications in manufacturing and automation processes.
