Product Description:

The MAC112B-0-LD-2-C/130-A-0/S037 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it accepts current-controlled commands from legacy drive modules and converts them into precise shaft rotation for industrial positioning, indexing, and coordinated motion tasks. This motor format is commonly used where the amplifier closes the speed loop with analog feedback instead of a digital network. The design suits automated equipment that needs consistent velocity regulation and straightforward integration with existing control hardware.

Its centering flange measures 130 mm, allowing direct seating in standard machine housings without alignment bushings. Heat is removed solely through natural convection, so airflow around the housing should remain unobstructed, and this passive cooling method eliminates fan noise and auxiliary wiring. Rotor speed reference is supplied by integral tacho feedback, which generates a proportional signal of 3 V/1000 rpm. Under rated excitation, the shaft reaches 2000 rpm, making the motor suitable for medium-speed tool or transfer lines. The tacho element is graded as standard quality for analog velocity loops that do not require high-resolution encoder feedback.

The motor has length code B and frame size 112, giving it a compact form factor relative to its output class. Phase conductors terminate through a connector on side A, which simplifies cable routing along linear axes and machine frames. This layout is useful where harnesses need to stay clear of moving tooling and guards. Winding code LD indicates the stator impedance and thermal characteristics expected by matching MAC drives. The motor is supplied without a blocking brake, so stopping torque must be provided by the drive or by external clamps when the axis is at rest.
