Product Description:

The MAC112C-0-HD-4-C/130-A-0/I-625/S005 servo motor from Bosch Rexroth Indramat is part of the MAC AC Servo Motors series. This motor is intended for analog drive systems where closed-loop velocity and position control are required. Within an automation cell, it converts electrical input from a drive into mechanical shaft rotation for axes that demand coordinated motion. The unit is supplied without a blocking brake, so external mechanisms or drive torque must hold position whenever power is removed. This arrangement suits transfer, indexing, and positioning axes that rely on steady speed regulation during repeated machine cycles.

The frame has a motor size of 112, and the centering diameter measures 130 mm, providing a reference surface for concentric mounting to gearboxes or machine frames. Length code C identifies the active stack height, which supports continuous torque output while keeping the overall package length consistent with neighboring models. The HD winding code sets the current and voltage characteristics expected by compatible drive units. Under rated excitation, the rotor can reach 2000 rpm, a base speed suited to general-purpose point-to-point and cyclic motion tasks. That operating range fits many automation axes that need responsive movement without sacrificing stable low-speed behavior.

Cooling relies on natural convection, allowing operation without external blowers where cabinet airflow is limited. The three-phase power leads exit through a connector on side A, which can simplify cable routing when the motor flange faces forward. For commutation and speed control, the unit uses an incremental or absolute encoder with tachofeedback hardware. Its tachogenerator outputs 3 V/1000 rpm, giving the drive a linear voltage reference for velocity loops. This feedback arrangement allows analog regulators to process speed and position-related signals with consistent response during normal machine operation.
