Product Description:

The MAC090C-0-GD-3-C/110-A-0/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It converts command voltages into precise rotational movement for positioning, indexing, and speed-regulated tasks in automated machinery such as transfer axes, indexing tables, and feed systems that depend on repeatable motion. As a motor for analog drives, current control, commutation, and protective functions remain in the external amplifier rather than inside the motor, which keeps the motor itself focused on electromechanical output.

Thermal dissipation is handled solely by natural convection, so installation must allow free airflow around the housing without an auxiliary fan or liquid circuit. Alignment to gearboxes or machine frames relies on a centering register that measures 110 mm in diameter, which helps keep couplings, shafts, and mounting faces properly aligned during operation. The electromagnetic profile uses winding code GD; this code indicates the wire gauge and turn count that set current draw and torque constants, so the matched amplifier sees the expected electrical behavior. Power conductors are routed through a single connector on side A, simplifying cable layouts where space on the opposite flank is restricted. The motor is supplied with no blocking brake, so external hardware or drive torque must hold the load stationary during power-off events.

The motor includes tacho feedback and a second shaft end; the tachometer supplies an analog speed signal, while the auxiliary shaft permits an additional encoder or another mechanically linked device to be coupled. Velocity data accuracy follows a standard tacho quality grade that is suitable for general motion loops, basic speed regulation, and conventional servo applications, but it is not intended for high-resolution contouring. This arrangement supports older amplifier platforms that rely on analog speed feedback, and the rear shaft extension can be useful where the axis layout requires supplemental feedback or a secondary mechanical connection.
