Product Description:
The MAC090C-0-GD-4-C/110-A-0/MR139/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is supplied for use with analog drive controllers where precise torque and speed regulation are required in automated machinery, material-handling axes, and packaging actuators. Within an installation, the motor converts controlled current from the drive into rotary motion while forwarding position information back to the control loop through its built-in feedback interface. Its feedback arrangement supports positioning axes that need stable low-speed behavior and repeatable speed control during continuous machine cycles.
A centering flange diameter of 110 mm aligns the housing concentrically with gearboxes or mounting plates and promotes vibration-free coupling. Heat generated in the stator is removed solely by natural convection, so no external blower or liquid circuit is needed and cabinet airflow must remain unobstructed. Rotor position is reported through tacho feedback or an incremental or absolute encoder, allowing legacy tacho loops or modern counting methods from the same motor type. Power conductors leave the stator through a connector on side A, which sets cable routing and panel clearances during design. The electromagnetic circuit uses winding code GD, which indicates the wire gauge and turns count selected for the voltage, current, and speed profile of this frame size.
The motor has no blocking brake, so mechanical holding must be provided externally whenever static load retention is critical. The velocity signal quality supplied by the tacho devices is rated as Standard, which matches the needs of most indexing or contouring applications without additional filtering. Because it is a motor for analog drives, the unit interfaces directly with proportional amplifier stages rather than fully digital inverters. This control approach is useful in existing machine platforms that retain proportional amplifier stages and analog command structures.
