Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI520LX/S05 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, the unit converts current-controlled commands into precise shaft rotation that positions axes in automated machinery such as pick-and-place heads, gantry loaders, and indexing tables. Integrated tachometer and encoder interfaces allow the paired drive electronics to monitor velocity and position without external transducers, supporting closed-loop motion control in industrial automation.

Its mounting flange provides a centering diameter of 130 mm, aligning the shaft concentrically with gearboxes and minimizing radial runout. Power conductors enter through a connector on side A, simplifying cable routing in compact machine layouts. Heat generated in the stator dissipates by natural convection, so no forced-air or liquid-cooling accessories are required. The motor reaches a nominal speed of 3000 rpm, so drive tuning should consider mechanical resonance below this operating point. For vertical or high-inertia loads, an integrated brake supplies 45 Nm of static holding torque that secures the axis whenever power is removed. Winding code ED indicates the resistance and inductance values expected by standard MAC analog amplifiers, supporting electrical compatibility.

Frame size code 112 and length code C indicate the overall mass and thermal capacity needed for mid-range servo applications, which helps predict inertia and continuous torque without oversizing the system. The built-in tacho delivers 3 V/1000 rpm, supplying a linear velocity signal that simplifies proportional feedback loops in analog control cards. When positional accuracy is required, an incremental encoder with standard mounting emits equally spaced pulses and marker channels, synchronizing motion sequences across multiple axes while remaining compatible with legacy counting electronics.
