Product Description:

The MAC112D-1-FD-4-C/130-A-0/WI518LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it is intended to deliver precise torque and speed regulation in industrial positioning axes and feed drives. It converts commanded current into rotary motion for machine axes that require repeatable acceleration, smooth speed control, and stable low-speed behavior. This model is supplied without a blocking brake, so mechanical holding must be provided externally when power is removed. Its integrated design allows direct mounting on automated machinery while maintaining electrical compatibility with legacy analog amplifiers.

Cooling is provided by axial surface cooling, which channels forced air along the stator jacket to maintain stable operating temperature. Airflow comes from a blower operating at AC 230 V, eliminating the need for separate cabinet fans. The stator housing uses a 130 mm centering pilot for accurate alignment against gearboxes or machine plates. Under rated excitation, the rotor reaches 2000 rpm, a nominal speed that suits many feed-drive applications. The electromagnetic circuit uses winding code FD, so the motor presents the electrical characteristics expected by a compatible analog drive. A tacho feedback channel and either incremental or absolute encoder outputs support closed-loop velocity and position control.

The motor has a frame size of 112, and the overall depth corresponds to length code D, which keeps the unit compact for its power class. Electrical power is delivered through a connector on side A, which can simplify cable routing in right-hand mounting layouts. The integrated tacho generator produces 3 V/1000 rpm for analog velocity feedback. An incremental encoder with standard mounting supplies precise position data for the control system. The feedback arrangement connects directly to matching analog control hardware and supports accurate axis response during normal operation.
