Product Description:

The MAC117B-0-WS-4-C-130-B-1-WI511LV is an AC servo motor supplied by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive current into controlled torque so machine axes can hold position, follow velocity profiles, or execute precise indexing routines in automated production lines. Compact mounting dimensions and compatibility with Rexroth analog amplifiers make it suitable for retrofits where digital interfaces are not yet available.

Frame size 117 establishes the stator diameter and determines the mounting bolt circle, while a centering recess of 130 mm aligns the housing to gearboxes or machine plates without additional shims. Heat that develops in the winding is dispersed by natural convection, so the motor can be installed without forced-air ducts provided ambient airflow is not obstructed. Electrical loading is matched to winding code WS, which identifies the copper fill and impedance used with compatible analog amplifiers. Power leads exit through a connector on side B, allowing cable trays to remain on the non-drive end of the machine and simplifying service loops.

Length code B gives a rotor stack deep enough to generate the torque range expected from this frame size without increasing diameter. Position sensing is handled by an incremental encoder that provides quadrature signals, and the assembly also carries tacho feedback so velocity data can be fed directly to analog controllers. The feedback configuration can also accept an absolute module. A factory-installed blocking brake prevents shaft rotation when power is removed, which is useful for vertical loads. Signal fidelity is supported by standard tacho quality, which meets the accuracy limits of legacy velocity-loop hardware.
