Product Description:

The MAC112B-0-GD-4-C/180-A-0/WI504LV/S011 servo unit is built by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is a brushless rotary motor designed for analog drives that require closed-loop speed and torque control in automated production lines, material-handling stations, and machine tools. Integrated tachometer feedback lets the connected controller regulate motion precisely without external sensors. This arrangement supports stable axis response during repeated starts, stops, and speed changes where consistent motor behavior is important.

Mechanically, the stator housing centers on a pilot diameter of 180 mm, which helps keep the shaft concentric with mating equipment. Heat from the windings is dissipated solely by natural convection, so continuous operation depends on free air circulation around the housing ribs. The electromagnetic layout uses winding code GD, matching the electrical characteristics expected by the analog amplifier. Frame size 112 gives the motor its mounting pattern and overall width within the MAC platform. For electrical hookup, a connector on side A places the power connection in a position that can simplify cable routing near the machine structure.

Torque is transmitted through a DIN 6885 keyway, providing positive shaft engagement for belts, gears, or couplings. Rotor position information reaches the amplifier through an internal tachogenerator and an incremental encoder mounted in the standard fixture, allowing the drive to monitor speed and position during operation. The motor has no holding brake, so vertical axes need an external brake or another method of load retention when power is removed. The axial build with length code B gives the motor a medium stack length that supports general-purpose motion duties without making the housing unusually long. Tachometer accuracy is rated at the standard level used for medium-speed packaging and assembly stations.
