Product Description:

The Bosch Rexroth Indramat MAC112C-2-HD-4-C/130-A-0/WI520/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts commanded currents into controlled torque and speed for industrial axes that require repeatable motion profiles. The design couples an HD winding set with a frame length labeled C, allowing the unit to achieve its rated output while fitting into machinery that follows the 112 frame standard.

Thermal regulation relies on Axial Surface Cooling; a blower integrated on the housing forces air along the fins to extract heat. That blower operates from a supply of AC 115 V, removing the need for an external low-voltage fan circuit. The motor centers on a 130 mm pilot diameter that aligns the stator accurately with the machine flange and maintains concentricity during high-load duty. At its nominal operating point the rotor turns at 2000 min⁻¹, matching analog velocity loops used in presses and gantries. With a frame designation of size 112, the stator stack provides the magnetic cross-section needed for medium power applications without increasing overall envelope.

The electrical terminations for phase conductors are routed through a Connector to side A, simplifying cabinet wiring when the motor is mounted with its shaft facing the line. Position information is furnished by an Incremental encoder with standard mounting, while a separate tacho generator delivers a feedback signal of 3 V/1000 min⁻¹ that supports velocity control with standard tacho quality. Because there is no blocking brake, the axis must rely on drive torque or external mechanics to hold position when power is removed. The HD winding code, the standard tacho assembly, and the C length stack together define the electrical constants that let the analog controller reach commanded torque without saturation.
