Product Description:

The SG-B0.002.091-03.000 is a brushless synchronous servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It targets compact automation axes that demand quick velocity changes and reliable position retention. A small integrated brake is already installed, so the motor can hold a load without external clamps when control power is lost. The smooth 9 mm shaft supports direct coupling to miniature gearheads, while the sealed housing helps keep lubrication in place and fine debris away from the internal bearings, allowing the device to operate close to sensitive production areas.

The motor attaches to a machine plate through a precision flange that measures 55 mm across, establishing the mechanical datum for concentric alignment. Under rated conditions, the rotor reaches a nominal speed of 8100 rpm; this high base speed enables short cycle times in pick-and-place or spindle-type tasks. At standstill, the electromagnetic circuit develops 0.25 Nm of torque, enough to overcome static friction in light loads without overheating. Drawing a standstill current of 0.92 A, the winding temperature rise stays within insulation limits, which is important when the axis remains stopped for extended periods between moves.

Once the brake is engaged, a holding torque of 1.0 Nm resists back-driving forces, and the brake coil consumes only 11 W, reducing control panel power demand. The housing carries an ingress rating of IP65, so it is protected against dust and low-pressure water jets without extra covers. Dynamic response is aided by a low rotor inertia of 0.009×10⁻³ kg·m², which minimizes the torque required for rapid speed changes. Including the brake, the assembly weighs just 1.2 kg, easing installation on lightweight gantries and articulated arms.
