Product Description:

The MAC112B-0-GD-1-B/130-A-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, it converts continuous voltage commands into regulated shaft torque and speed for feed axes, pick-and-place stations, and positioning tables in automated lines. The motor provides a matched mechanical and electrical interface for use with compatible analog amplifiers. It is intended for machinery that relies on continuous closed-loop adjustment rather than simple fixed-speed operation.

A centering flange of 130 mm aligns the housing inside precision machine frames, while the frame size of 112 sets the overall cross-section and shaft height. During routine stops, the blocking brake can restrain up to 45 Nm of static torque, helping prevent drift on vertical axes. Heat is removed by natural convection, eliminating the need for external blowers and keeping operation quiet. An incremental encoder feedback unit mounted at the rear delivers phase-quadrature signals for speed control and incremental position tracking. Because the encoder reports incremental motion rather than absolute position, the connected control interprets pulse counts to monitor shaft movement and direction.

The brake supply is Standard, indicating a factory-fitted mechanical brake rather than an optional kit. Axial depth corresponds to motor length code B, which gives a balance between continuous torque and installation space. Power leads exit through a connector on side A, so machine wiring can stay on one face of the base and clear adjacent modules. This arrangement supports orderly cable routing where space is limited and connections must remain accessible. Electromagnetic properties follow winding code GD, allowing the paired drive to reach its rated current and voltage without retuning.
