Product Description:

The MAC112B-0-GD-4-C/130-A-0/WI520L/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It operates as a motor for analog drives, converting commanded current into precise rotary motion for positioning or velocity control in automated equipment. Integration of this unit into machine tools, packaging stations, or material-handling axes allows consistent closed-loop performance without adding external sensors to the load side. Its integrated feedback arrangement lets the paired drive monitor motion directly at the motor, which helps maintain stable response during speed changes and repeated positioning tasks. This arrangement is useful on axes where compact packaging is important because feedback devices do not need to be mounted separately on the machine structure.

This model seats against a mounting pilot that measures 130 mm in diameter, so the housing centers accurately on compatible mechanical flanges. Heat generated in the stator windings is removed by natural convection, eliminating the need for forced air or liquid cooling hardware. With frame size 112, the motor fits applications that need more torque capacity than smaller housings without taking up excessive installation space. Length code B indicates the active magnetic stack depth, providing a balanced combination of torque output and overall size for mid-range duty cycles. Winding code GD identifies the coil variant used in this motor, allowing compatible analog drive amplifiers to match current and speed behavior across the operating range.

No holding torque is available when power is removed because the motor has no blocking brake, so vertical axes require an external holding method. Power conductors exit through a connector on side A, which can simplify cable routing when the cabinet or cable track is positioned on that side of the machine. Rotor position is monitored through a feedback pack that provides tacho feedback with incremental or absolute encoder options, giving both legacy and newer control systems suitable signal options. For pulse-based motion control, the unit uses an incremental encoder with standard mounting, which supports common feedback arrangements and keeps mechanical alignment straightforward during installation.
