Product Description:

Bosch Rexroth Indramat manufactures the MAC112B-1-GD-2HC/130-B-0/S005 within the MAC AC Servo Motors series. This model is a motor for analog drives and is intended to provide closed-loop torque and velocity control on automated axes such as gantry arms, indexing tables, and packaging formers. By converting commands from an external amplifier into precisely metered rotary motion, the unit serves as the electromechanical link between the drive electronics and the load. This operating mode is useful in machines that rely on stable speed control and repeatable motion during frequent starts, stops, and load changes.

The motor employs AC 230 V blower power to move cooling air across its housing, and the axial surface cooling arrangement removes heat without enlarging the frame. A 130 mm centering diameter aligns the flange to gearboxes or machine plates, which helps keep runout low as the shaft accelerates and decelerates. Position feedback is delivered through tacho feedback, and the internal sensor is graded as standard quality for routine speed regulation. The motor uses frame size 112, which sets the stator cross-section, while the GD winding code indicates the wire dimensions and turns used to match analog converters in this motor class. A blocking brake is not present, so holding torque must be provided by the drive or an external mechanical lock.

The tachogenerator outputs 1.5 V/1000 rpm, giving the controller a proportional voltage that scales linearly with shaft speed for analog velocity loops. Power leads exit through a connector on side B, which can simplify routing when the motor is mounted against bulkheads or other nearby machine surfaces. The motor has a length B housing, which balances inertia and continuous torque for mid-range duty. Axial vents in the housing support the blower airflow path across the motor surface.
