Product Description:

The MAC115B-0-GS-4-C/130-B-0/AM164SG is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current from a matching amplifier into controlled torque and speed for automated machinery, conveyors, and assembly modules. It is intended for motion applications that require stable speed regulation and repeatable positioning during normal machine operation.

The size code 115 sets the stator frame dimensions and shaft height, allowing mechanical interchange with other motors that share this footprint. Its nominal speed of 2000 rpm is the continuous operating velocity at rated conditions and helps match the motor to gearbox ratios or direct-drive requirements. A centering diameter of 130 mm aligns the flange on mounting plates, which helps reduce radial runout during installation. Heat is dissipated by natural convection, so no external blower or liquid circuit is required. The winding code GS identifies the stator winding pattern and resistance used by the analog controller.

A mechanical blocking brake is not present, so vertical axes must rely on external holding methods when power is removed. Position and velocity feedback are provided through an incremental tacho generator that delivers 3 V/1000 rpm, and the feedback signals are routed through the integrated connector. Power conductors exit through a connector on side B, which can simplify cable routing when that face is accessible. For closed-loop positioning tasks that require nonvolatile reference data, the available absolute encoder allows the drive to restore position immediately after a restart. The motor length is coded B, indicating a mid-length rotor stack that balances inertia with continuous torque, and the tacho quality is standard for general-purpose precision tasks.
