Product Description:

The SG-A1.006.072-00.000 is a brushless servo motor developed by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. As a compact rotary actuator, the unit converts electrical drive commands into high-speed, closed-loop spindle motion for packaging, printing, and pick-and-place axes. Its resolver feedback supplies real-time rotor position data to a compatible drive controller, allowing tight velocity and position regulation in modern industrial automation lines.

Operation is permitted at ambient temperatures from 0 to 40 °C, so the motor can be installed directly in standard machine enclosures without supplemental climate control. At its rated supply, the rotor reaches a nominal speed of 8800 rpm, providing fast cycle times when paired with high-ratio gearheads or direct-drive spindles. Heat is removed through thermal radiation and natural convection, so no forced-air blower or liquid cooling circuit is required. The sealed housing has an ingress protection rating of IP65, blocking dust and low-pressure water jets during washdown or exposure to lubricants. Internally, the windings use Class F insulation according to VDE 0530, permitting winding temperatures up to 155 °C before derating is necessary.

The mechanical interface follows the IM B5 mounting pattern and uses a 70 mm flange machined to accuracy grade N, allowing direct coupling to compact planetary gearboxes. Torque is transferred through a keyed spindle that measures 11 mm × 23 mm and accepts DIN 6885 feather keys for positive drive engagement. High-energy SmCo magnets provide stable magnetic flux at elevated temperatures, maintaining a linear response during rapid acceleration. Because the motor is supplied without a holding brake, static load retention must be handled by the drive or an external clamp. The resolver occupies minimal space at the stator end. The power leads terminate in a mating connector sized for 1.5 mm² conductors, while vibration severity grade N supports balanced operation.
