Product Description:

The SG-B1.023.042-04.000 is a brushless servo motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. Designed for industrial automation, the unit converts electrical energy into precisely regulated shaft rotation for indexing tables, small gantries, and packaging equipment. A resolver embedded in the stator supplies rotor-position feedback, allowing closed-loop drives to command accurate velocity and position. The metal housing protects the internal components and provides a rigid structure for operation under changing mechanical loads. The motor supports flange mounting under IM B5 arrangements commonly used in compact machine frames.

The large integrated holding brake operates from a supply of 24 V DC ±10% and secures mechanical loads whenever the drive is disabled. The rotor can reach a nominal speed of 4800 rpm, making the motor suitable for applications that require responsive motion over a broad operating range. A standstill current of 4.8 A supports torque production when the shaft is stationary. The brake can apply a static holding torque of 3.0 Nm, while the electromagnetic system produces a static torque of 2.55 Nm during drive-controlled positioning. Thermal radiation and natural convection remove heat from the frame, eliminating the need for forced airflow and reducing the number of external cooling components.

The mechanical connection uses a 70 mm output flange machined to accuracy class N, and the enclosure has an IP65 rating for protection against dust and low-pressure water jets. The motor uses SmCo permanent magnets, which provide a high coercive field that resists demagnetization during dynamic operating cycles. Its windings have class F insulation according to VDE 0530, permitting winding temperatures up to 155 °C. The keyed shaft follows DIN 6885 and measures 11 mm in diameter and 23 mm in length, while the mating connector accepts conductors with a cross-sectional area of 1.5 mm². Operation is permitted at ambient temperatures from 0 °C to 40 °C, and the frame can be installed in IM V1 or IM V3 orientations without a change in performance.
