Product Description:

The MAC115B-1-ES-4-C/130-A-1/WI524LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, it supplies regulated torque and speed to positioning axes, conveyors, and other equipment in automated plants. An external blower manages frame temperature during continuous duty, and the built-in feedback devices support closed-loop operation in multi-axis systems.

A centering shoulder of 130 mm aligns the flange with adjoining machine frames, which helps maintain concentricity during mounting. Frame designation 115 identifies the stator width and pairs the motor with matching MAC gear units. Heat is removed through axial surface cooling, and the external blower runs at AC 230 V, providing airflow independent of shaft speed. The integrated blocking brake supplies 45 Nm of holding torque so vertical loads remain fixed when the drive is disabled. This helps prevent load drift when the axis is at a standstill. With motor length code B, the active stack offers mid-range continuous output while keeping weight moderate. The motor also uses standard tacho quality for speed feedback in analog control loops.

Mechanical power is transmitted through a DIN 6885 keyway, which provides positive shaft coupling without additional locking devices. The three-phase supply terminals are brought out on a connector on side A, which keeps cabling on the drive end of the machine. Position data for the analog controller is generated by an incremental encoder mounted in the standard housing, and the same backplate can also accept tacho feedback or absolute encoder options when a different feedback arrangement is required. The motor uses winding code ES, which is tuned for the nominal voltage of the MAC115 frame and for low rotor inertia. This allows the same motor platform to support different feedback layouts without changing the basic housing.
