SD-B4.140.030-04.000

The Bosch Rexroth Indramat SD-B4.140.030-04.000 is a high-performance permanent-field servomotor from the SD Magnet Motors series by Bosch Rexroth Indramat. It features a brushless tacho located on the non-driving end and is equipped with Class F insulation for enhanced thermal endurance. Designed to integrate seamlessly with approved inverters, this servomotor delivers precise velocity feedback and rotor position detection via its built-in commutation sensor.

In terms of technical specifications, the SD-B4.140.030-04.000 utilizes an Electronic commutation type and operates at a maximum speed of 3000 rpm. The motor’s thermostat is of the NTC type, providing reliable temperature monitoring, while its constant torque design ensures a stable torque output throughout the speed range. This unit is part of the SD family with a customization code of 0 and supports maintenance-free operation under ambient temperatures up to 40 °C. The combination of a brushless tacho, commutation sensor, and robust thermal management underscores its overload capacity and control accuracy.

Built for industrial environments, the servomotor is cooled by natural convection and thermal radiation and is highly resistant to demagnetization. Its completely sealed housing achieves an IP 54 protection rating, safeguarding against dust and splashing water. The device includes a disk brake with keyway and featherkey shaft interface; mating connectors are available separately. With no secondary shaft end, visible type plate, and a maximum theoretical acceleration of 9900 rad/s², this servomotor offers reliable efficiency and durability. Ideal for mechanical engineering applications, it enhances precision, reduces maintenance downtime, and supports the manufacturer’s Servodyn drive concept for optimized automation performance.
