Product Description:
The SG-B1.006.072-00.000 synchronous servo motor is produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It is a brushless servo unit with a metal housing that supports high-speed, closed-loop positioning in automated pick-and-place equipment, spindles, and feed-axis assemblies. The motor integrates a resolver that relays rotor orientation and speed data to the drive, enabling precise electronic commutation and feedback control in industrial automation. Its brushless design also avoids the mechanical wear and electrical noise associated with commutators and carbon brushes.
The motor reaches a nominal speed of 8800 rpm, allowing short cycle times in machinery that requires rapid acceleration. A rotor made with SmCo permanent magnets maintains its magnetic strength across a wide temperature range, so torque production remains stable during continuous operation. Its square mounting interface has a flange size of 70 mm, and its dimensional tolerances meet Flange Accuracy N for repeatable alignment. The motor uses an IM B5 mounting style, while the IM V1 and IM V3 vertical orientations are also permitted when installation space is limited. An enclosure rating of IP65 prevents dust and water jets from reaching the stator windings when the motor operates near coolant spray or airborne particles.
The permitted ambient operating temperature is 0 to 40 °C, so surrounding air must remain within this range during use. The windings have Class F insulation in accordance with VDE 0530, permitting conductor temperatures up to 155 °C without insulation degradation. Power reaches the stator through a mating connector that accepts conductors up to 1.5 mm². Output torque is transmitted through a keyway shaft measuring 11 mm × 23 mm, and the shaft follows DIN 6885 guidelines. The motor is supplied without a holding brake, so an external clamping device is required when a stationary load must be retained after power is removed. Heat is dissipated through thermal radiation and natural convection, while vibration severity is limited to Grade N to support smooth operation across the permitted speed range.
