Product Description:
The MAC112A-0-VD-1-B servo motor is produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. As an AC servo unit, it pairs with analog drive controllers to deliver closed-loop torque and speed control on automated machine axes. It is suited for precise positioning and stable velocity regulation in material handling systems, packaging stations, and general factory automation. The compact format also helps when the motor must fit into machine sections where installation space is limited but repeatable motion is still required.
The motor relies on natural convection, so heat is removed through the housing without forced airflow. A frame designation of 112 indicates the stator diameter in millimeters and helps guide mechanical mounting choices. Under rated load, the shaft turns at 2000 rpm, a speed that matches many standard gear ratios while still supporting responsive axis motion. Rotor position is transmitted to the controller by incremental encoder feedback, allowing fine resolution for velocity loops while keeping signal wiring straightforward. This feedback arrangement lets the controller monitor rotor movement continuously and correct speed deviations during acceleration or load changes. Matched motor and drive components also help keep electrical interfacing and feedback handling straightforward.
The axial construction is identified by length code A, which is the shortest stack in the MAC112 frame and helps lower inertia for rapid acceleration. Coil design marked as VD indicates the resistance, inductance, and rated current expected by the matching power module. When a separate velocity monitor is needed, the built-in tacho generator provides 3 V/1000 rpm, creating a linear analog signal that is proportional to shaft speed. As a motor for analog drives, the unit accepts current commands from control systems that use analog signaling rather than digital communication. The tacho signal can also support external monitoring circuits that require a speed-proportional analog output.
