Product Description:

The MAC090C-0-GD-4-C/110-A-2/AM164SG/S013 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it supplies precise shaft torque, speed, and position control for machine tools, packaging equipment, and handling modules in industrial automation. Its feedback package supports controlled motion on axes that require consistent speed regulation and repeatable positioning. The motor is suited to applications that need smooth acceleration, stable low-speed operation, and accurate reversal during repeated cycles.

Mechanical alignment is handled by a centering diameter of 110 mm, ensuring concentric seating against machine flanges while keeping coupling error low. Electromagnetic behavior follows the GD winding code, which indicates the phase resistance and inductance used by matching analog controllers. Thermal limits are maintained through natural convection, so fins cast into the housing dissipate heat without auxiliary blowers. Power leads exit through a connector on side A, and a heavy-duty blocking brake is mounted on the non-drive end to hold the rotor when the brake coil is de-energized. This arrangement supports clean cable routing in tightly packed machinery and preserves access to the mounting face.

Rotor speed is derived from a tachogenerator with standard tacho quality, while shaft position is supplied by an absolute encoder, which eliminates homing routines after power cycles. This dual-channel feedback arrangement gives the controller separate speed and position signals for closed-loop operation. Separate speed and position signals help the paired controller react quickly to load changes during indexing and feed motions. The motor can be used where legacy amplifiers still rely on analog reference voltages rather than digital fieldbus communication. The selected frame length supports medium-size axes that need a balance of inertia and continuous torque without fan-assisted cooling.
