Product Description:

The MAC115B-0-GS-3-C/130-A-0/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog speed- and torque-controlled axes in packaging, handling, and general automation equipment. In these systems, the motor works with a matched servo amplifier and converts electrical power into regulated rotation for closed-loop motion. This arrangement supports repeatable speed control and stable torque delivery during routine machine cycles, including repeated starts and stops.

The motor uses frame size 115, and the housing seats on a centering pilot of 130 mm to keep alignment accurate at the machine interface. It uses winding code GS, which gives the electrical characteristics expected by a matching analog drive. Under nominal conditions, the rotor runs at 2000 rpm, a speed that fits many medium-inertia axes. Velocity feedback comes from an internal tacho rated at 3 V/1000 rpm, giving the amplifier a proportional signal for continuous regulation. The B-length housing provides a moderate motor envelope while preserving the shaft geometry used for direct mounting or gearbox coupling.

Cooling is provided by natural convection, so installation space around the cooling ribs should remain open for air movement. Power reaches the stator through a connector on side A, which can simplify cable routing when the motor is mounted against a machine wall or frame. The feedback arrangement is listed as with tacho feedback and a second shaft end, allowing the rear shaft extension to support an auxiliary device when needed. The motor has no internal brake, so any load that must stay fixed at standstill requires holding torque from the drive or an external restraint. This layout keeps the electrical connection and shaft arrangement straightforward for analog servo installations.
