Product Description:

The MAC090A-0-RD-4-C/110-B-0W1315 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended to drive axes controlled by analog amplifiers, where closed-loop velocity or position regulation is handled externally. By converting electrical input from the drive into controlled mechanical rotation, the unit fits tasks such as indexing tables, pick-and-place gantries, and other medium-inertia loads common in automated lines. This operating style is typical of systems that keep command processing and loop tuning in the paired amplifier rather than inside the motor.

The housing aligns to machinery by means of a centering flange that measures 110 mm in diameter, helping prevent radial misalignment when bolted into place. Heat produced by copper losses is removed through natural convection, so no external blower or liquid circuit is required. Power conductors are routed through a connector on side B, keeping the opposite face free for feedback cabling or mechanical options. That cable arrangement can also simplify routing in compact machine frames by separating high-current wiring from other connections. Rotor position and speed are returned to the drive through incremental or absolute encoder signals generated by the built-in feedback package. The velocity monitor uses standard tacho quality, which suits general-purpose motion tasks that do not require a specialized precision grade.

This motor is supplied without a blocking brake, so applications that need power-off holding torque must rely on external clamping devices or remain energized. Its designation as a motor for analog drives means the electrical interface expects current-controlled amplifiers rather than fully digital fieldbus devices. That arrangement supports use in legacy motion systems where the external controller and amplifier handle regulation functions. It also allows the motor to fit installations that already use established analog command structures and separate feedback processing.
