Product Description:

The MAC112D-0-FD-2-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts commanded current into proportional torque and speed for axis control in machine tools, material-handling systems, and other industrial equipment. These applications often rely on proportional voltage amplifiers rather than fully digital motion platforms, so the motor is suited to legacy motion systems that still require stable feedback and predictable response.

A centering pilot of 130 mm positions the flange accurately and limits radial runout during installation. Heat generated in the windings leaves the housing through natural convection, eliminating the need for auxiliary blowers. With rated excitation, the rotor reaches 2000 rpm, matching the operating range expected from this frame. Power conductors terminate on a connector on side A, which simplifies cabinet wiring when the shaft faces the process. Electromagnetic behavior follows winding code FD, which identifies the resistance, inductance, and current limits used by compatible analog power stages. Velocity information is provided by a tachogenerator with a standard quality classification for general-purpose motion loops.

The motor length D pairs with frame size 112 to set shaft height, mass, and inertia for load-coupling calculations. Position retention must be handled externally because the unit is supplied without a blocking brake, which reduces weight and removes brake-release circuitry. When the axis must remain stationary after power is removed, holding torque has to come from the drive or a separate mechanical device. The tachogenerator produces 3 V/1000 rpm, keeping analog speed signals within common ±10 V interface ranges used by legacy controllers. This arrangement supports straightforward integration in existing servo systems that depend on passive cooling and continuous speed feedback.
