Product Description:

The MAC112D-0-HD-3-C/180-A-0/S03 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for analog drives and converts command voltages from legacy amplifiers into controlled torque for machine axes, conveyors, and tooling spindles in general industrial automation. Its mechanical interface and electrical feedback allow it to fit motion-control systems that still rely on older analog servo architecture. This makes it suitable for retrofit installations that continue to use existing analog command chains and feedback processing.

The motor seats against a register of 180 mm, aligning the stator housing accurately to reduce runout in coupling systems. Heat is removed by natural convection, permitting installation without auxiliary blowers while still keeping winding temperature within limits. Under rated excitation, the rotor reaches 1500 rpm, a synchronous speed suited to gearless direct-drive layouts. A tachogenerator delivers 3 V/1000 rpm, allowing analog controllers to monitor velocity through proportional voltage feedback. The electromagnetic circuit uses winding code HD, which corresponds to resistance and inductance values matched to compatible drive modules. The motor has no blocking brake, so the axis must rely on external holding devices when power is off.

Its feedback arrangement includes tacho feedback and a second shaft end, enabling an additional encoder or mechanical load to be coupled without changing the primary drive face. That layout can also support applications where auxiliary rotary components must be connected directly to the motor. The motor size is 112, and length code D indicates the fourth stator stack for higher continuous torque within this frame. Power conductors enter through a connector on side A, which can simplify cable routing when the motor is mounted with its fan side toward the cabinet.
