Product Description:

The SG-A3.055.049-00.000 is a synchronous servo motor engineered by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. It converts electrical energy into tightly controlled rotary motion, making it suitable for indexing tables, packaging axes, and similar industrial automation tasks that need repeatable positioning and speed regulation. By coupling with a compatible drive controller, the motor provides the torque and velocity loop closure required for closed-loop machinery in assembly or material-handling lines. Its operating role also suits applications that need frequent starts, stops, and controlled speed changes without sacrificing positioning consistency.

The mounting form is IM B5, which means the housing uses face-flange mounting without feet and can fit compact machine layouts with short overall length. A flange drilled to the DIN 42948 pattern supports compatibility with machines that use the same mounting standard. Flange accuracy grade N sets the permitted runout and concentricity so the shaft remains properly aligned with the driven load during repeated motion cycles. Output geometry follows the DIN 748 shaft standard, which helps couplings and hubs fit without special rework. The motor uses a smooth shaft, allowing torque transmission through friction-locking elements such as shrink disks or collet couplers where low backlash is important.

The enclosure carries an IP65 rating, which helps protect internal parts in dusty production areas and in locations exposed to cleaning spray. Rotor position is reported by a 2-pole resolver, providing analog sine-cosine feedback that the connected drive can interpolate for motion control and commutation. Winding temperature is monitored by an embedded NTC thermistor, and the drive can reduce current if rising temperature approaches a harmful level. The motor is supplied without a mating connector, which leaves connector selection open for existing cable sets and enclosure entry requirements. This arrangement can simplify integration where cable routing or connector style must match the rest of the machine.
