Product Description:

The MAC112D-0-ED-4-C/130-A-2/WI520/S013 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for use with analog drives, it converts current-controlled commands into precise shaft motion for positioning and velocity control in automated machines. The motor uses the manufacturer’s 112 frame classification, placing it in mid-torque applications such as material-handling axes and printing equipment. Its integrated feedback devices provide the signals required by a compatible amplifier to regulate movement as the mechanical load changes.

Mechanical holding is provided by a heavy-duty blocking brake rated at 60 Nm, allowing the shaft to remain locked when power is removed from a vertical or loaded axis. Thermal energy is dissipated through natural convection, so no external blower or liquid circuit is required, and the mounting arrangement must permit free airflow around the housing. At its nominal speed of 3000 rpm, the ED winding provides the electrical characteristics required by compatible legacy analog amplifiers. The winding code indicates the applicable resistance, inductance, and torque behavior for this motor configuration. Standard tacho quality supports repeatable voltage output for speed regulation. The motor has a D-length body, providing a magnetic stack depth that balances rotor inertia with continuous torque capability.

A 130 mm centering diameter aligns the flange with a gearbox or machine plate while limiting radial misalignment at the mounting interface. Power conductors exit through a connector on side A, simplifying cable routing where multiple axes are installed close together. Rotor position feedback is generated by an incremental encoder with standard mounting, which supplies position pulses to the connected drive. The integrated tacho produces 3 V/1000 rpm with standard accuracy for velocity control. These separate feedback signals allow the analog controller to monitor both rotor movement and shaft speed without relying on a single measurement channel. The resulting arrangement supports position-controlled and speed-regulated motion in machinery that uses compatible MAC motor drive equipment.
