Product Description:

The MAC112D-2-HD-4-C/130-A-0/W-I520LX/S005 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is an AC servo motor intended for analog drive systems where closed-loop speed and position control are required on production machinery. Within the series, it interfaces through tachometer feedback or a position encoder, allowing the associated drive to monitor rotational data in real time and command corrective torque as operating conditions change. This arrangement supports stable motion on axes that need repeatable response during continuous production cycles.

Heat is removed from the stator by axial surface cooling, and the integral blower operates from a supply of AC 115 V. Under rated load, the shaft turns at 1500 rpm, a speed chosen to match the frequency range of standard analog controllers while still permitting moderate gear reduction. During installation, the stator is centered in the machine frame by a 130 mm pilot, and electrical power is routed through a connector on side A so that cables exit in the same plane as the motor shaft. The motor has a D length, which provides additional stack height compared with shorter variants and increases continuous torque without changing the external mounting interface.

The motor has no blocking brake, so hold-position functions must be provided by the drive or external clamps. The stator uses winding code HD, which indicates the resistance and inductance values used with compatible MAC analog amplifiers. The motor has frame size 112, which corresponds to the bolt circle, shaft diameter, and magnetic cross-section used across the 112-series motors. For velocity feedback, the integrated tacho generates 3 V/1000 rpm, allowing the controller to derive speed error directly as a proportional voltage. That feedback format remains suitable for legacy control loops that expect a direct analog speed signal.
