Product Description:

The MAC112A-0-LD-1-B/130-A-0/J1250/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Intended for analog drive systems, this motor converts proportional command voltages into rotary motion for industrial automation tasks such as material transfer, precision tooling, and indexing operations. The design supports closed-loop velocity control while maintaining a compact footprint that fits existing mechanical assemblies. It is suited for machines that need repeatable motion with direct feedback to the drive during continuous operation.

The mechanical interface features a centering pilot of 130 mm, which helps align the motor accurately when it is bolted to gearboxes or mounting plates. Frame size code 112 identifies the stator diameter, and length code A indicates the shortest housing in this frame. Under rated excitation, the shaft reaches 3000 rpm, a speed that suits mid-range inertia loads and common servo applications. For direct speed signaling, an internal tacho generator outputs 3 V per 1000 rpm, giving the analog amplifier a linear voltage that follows actual shaft rotation. This arrangement allows the drive to monitor motor speed without requiring separate external sensing hardware.

Heat is removed by natural convection, so the housing depends on open surrounding airflow instead of forced cooling. Main power conductors terminate through a connector on side A, which supports straightforward cable routing at the drive end of the motor. Shaft position data is supplied by incremental encoder feedback, allowing the connected controller to process motion information for position and velocity regulation. The motor is delivered without a blocking brake, so any static holding function must come from external clamping hardware or active drive torque. Winding code LD matches the electrical characteristics of compatible MAC analog drives, helping the motor operate with the expected current response and stable thermal behavior during continuous duty.
