Product Description:

The MAC112C-0-KD-4-C/130-A-0/W1522/S021 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts drive-amplifier output into controlled rotary motion for machine axes, conveyors, and material-handling fixtures within automated cells. It uses permanent-magnet excitation and pairs with compatible analog drive modules to deliver closed-loop velocity and position control in industrial automation. This arrangement supports repeatable motion on axes that depend on stable speed regulation and accurate response to changing load conditions.

A centering diameter of 130 mm guides the housing into a flange recess and maintains concentricity with the driven load. The frame code 112 identifies the motor cross-section and matches standardized mounting patterns. Under rated conditions, the shaft reaches 1500 rpm, a speed that balances torque production with low acoustic noise. Heat is dissipated by natural convection, so additional fans or liquid circuits are unnecessary when ambient air can circulate freely. The KD winding code indicates the phase resistance and inductance used with compatible analog drive cards.

Signal handling is provided through W tachofeedback with an incremental or absolute encoder, giving the drive either velocity feedback from a tacho generator or multi-turn position data from an encoder. The integrated tacho delivers 3 V/1000 rpm, enabling the controller to calculate actual speed with minimal filtering. Power conductors exit through a connector on side A, simplifying cable routing when the motor is mounted inside tight enclosures. Because the motor has no blocking brake, holding torque during power-off must come from external brakes or the machine's mechanical couplings. The length code C indicates the rotor stack depth, contributing to the torque constant without changing the exterior frame size.
