Product Description:

The MAC112C-0-HD-4-C/130-A-1/WI520IV/S005 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. Classified as a motor for analog drives, it translates analog velocity or torque commands into controlled shaft motion for positioning, conveying, and tooling stations in automated lines. Within the series, it occupies the 112 frame class and is intended for direct integration where closed-loop control is required without switching to full digital interfaces. Integrated feedback channels allow the paired controller to monitor motion during operation. That makes the motor useful in systems that still rely on analog amplifiers but require repeatable rotary movement at the axis.

Mechanically, the rotor seats against a centering bore of 130 mm, matching the frame size 112 and motor length C. The winding code HD indicates the stator's electrical characteristics. Heat is removed by natural convection, so the installation must allow unobstructed ambient airflow around the housing. This cooling method avoids external fans, but the mounting area should not block heat from leaving the motor surface. Under rated excitation, the shaft reaches 2000 rpm, a speed that suits mid-range feed axes without gearbox multiplication. Power conductors terminate on a connector on side A, which helps direct the cable toward a consistent cabinet entry path.

For load holding during power-off, the integrated blocking brake supplies 45 Nm of static torque. Output torque is transferred to couplings through a DIN 6885 keyway, providing positive drive engagement. Speed feedback to the analog controller originates from a tacho generator that delivers 3 V/1000 rpm, while positional data is supplied by an incremental encoder with standard mounting. Using separate speed and position signals allows the drive system to support regulation and monitoring functions at the same time. The overall feedback arrangement allows tacho, incremental, or absolute encoder signals for use with legacy motion cards and later control updates.
