Product Description:

The MAC112D-0-HD-2-C/180-A-0/S011 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for analog drive systems where a rotary actuator must deliver commanded torque and speed with feedback regulation. In automated production lines, the unit serves as the primary mover for axes that perform indexed positioning, synchronized motion profiles, or continuous rotation under closed-loop control, and it can support machines that require repeatable rotary motion across changing process steps.

The motor is built on a centering flange that measures 180 mm, allowing precise radial alignment against gearboxes or machine frames. Heat is removed through natural convection, so installation must permit free airflow around the housing instead of relying on added cooling hardware. Rotor position and speed are monitored through tacho feedback, which supplies an analog signal to the drive for real-time regulation. A nominal operating speed of 1500 rpm suits applications that use converted 50/60 Hz line power, and the feedback signal helps the amplifier correct speed deviations during changing loads. Winding code HD indicates the resistance and inductance combination used for this torque-to-speed range.

With a frame size of 112, the motor has the corresponding stator diameter, while build length D increases the active stack depth and supports higher continuous torque without changing the mounting geometry. The tachogenerator produces 3 V per 1000 rpm, providing the drive with a proportional velocity signal for fine speed control across the operating range. Power conductors exit through a connector on side A, simplifying cable routing when the motor is mounted in tight cabinets. The motor does not include an internal blocking brake, so any holding function must be supplied externally when the axis is stopped.
