Product Description:

The MAC090C-0-GD-4-C/110-A-0/WI553/S001 is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. As a motor for analog drives, it converts drive commands from legacy voltage or current interfaces into precise mechanical rotation for positioning and speed control in automated machinery. Within an installation, it supplies torque directly to the driven axis, closing the loop with integrated feedback so that the associated controller can maintain repeatable motion profiles. This makes the motor suitable for older control platforms that still rely on analog command signals.

This motor attaches to the machine frame through a 110 mm centering diameter, which aligns the stator housing and helps limit radial runout. Heat generated in the stator is removed by natural convection cooling, so the installation must allow free ambient air circulation around the housing. Mains and protective-earth conductors are routed through a connector on side A, which can simplify cable runs where cabinet space is limited. The motor uses a incremental encoder with standard mounting to report rotor position, giving the analog drive system fine incremental counts for velocity regulation. The GD winding code identifies the electrical design used for phase resistance, inductance, and nominal voltage so the drive can supply the correct current.

The secondary feedback path can supply a tachofeedback, incremental, or absolute encoder signal, allowing the controller to cross-check velocity in high-precision loops. A standard tacho quality rating indicates ripple and offset levels suitable for ordinary servo bandwidths, which can reduce the need for extra filtering in the control circuit. Mechanical holding torque during power loss must be provided externally because the motor is delivered with no blocking brake. The feedback arrangement supports analog control systems that need direct speed feedback and position information during continuous operation. The motor remains part of the MAC AC Servo Motors line and uses passive cooling instead of added fan hardware.
