Product Description:

The SG-B1.034.036-00.046 is a brushless servo motor manufactured by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It delivers controlled rotary motion for positioning axes and feed drives where closed-loop accuracy and fast response are required in automated machinery. A resolver encoder supplies rotor position and speed feedback to the drive controller, allowing the controller to regulate movement as operating conditions change.

The motor has a nominal speed of 3900 rpm, while the windings draw 5.9 A at standstill to generate a static holding torque of 3.70 Nm. The flange measures 70 mm, matching common IEC interface patterns for direct mounting to gearheads or machine plates. The housing has an IP65 protection rating that prevents dust ingress and resists water jets. Mechanical installation follows the basic IM B5 orientation, with IM V1 or IM V3 arrangements also permitted when a vertical shaft is needed. The metallic construction supports heat transfer from the motor housing to the surrounding air. The unit dissipates losses through thermal radiation and natural convection, eliminating the need for forced-air cooling components.

The SmCo permanent magnets provide high coercivity and thermal stability for consistent torque across the operating range. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which is suitable for typical industrial environments. The shaft output is machined with a keyway and feather key in accordance with DIN 6885. The shaft journal measures 11 mm × 23 mm, allowing secure attachment to pulleys or couplings. Vibration severity is limited to Grade N, helping protect the bearings and connected components during rapid indexing. Class F insulation according to VDE 0530 withstands winding temperatures up to 155 °C, and a mating connector with a 1.5 mm² cross-section accommodates the power leads without derating. The motor is supplied without a holding brake, so external clamping or drive torque must secure the load when power is removed.
