Product Description:

The MAC090B-0-ND-3-C/130-A-1/S012 is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is engineered for analog drive systems, converting continuous control voltages into precise rotary motion for positioning and speed regulation on machine tools, handling modules, and other automated equipment. As part of older analog platforms, the unit supplies torque and velocity in response to voltage commands, making it suitable for retrofit applications where digital fieldbus interfaces are absent. This operating style lets the motor work with established control hardware that depends on stable analog command signals rather than network-based communication.

Mechanical alignment is handled by the centering diameter of 130 mm, which allows rigid seating in adapter flanges without misalignment. A standard blocking brake is integrated so the shaft can be held when the drive is disabled, which helps prevent drift on vertical axes or during stopped conditions. Heat is removed through natural convection, eliminating the need for forced-air accessories while keeping the cooling arrangement simple. Electrical power reaches the stator through a connector on side A, allowing cable routing along the motor’s reference face and leaving the opposite end open for coupling components. This arrangement supports orderly installation where the motor must fit into compact mechanical spaces without adding external cooling hardware.

Position feedback and velocity smoothing are provided by tacho feedback, and the design also offers a second shaft end for external encoders or belt drives when higher feedback resolution is needed. Classified as a motor for analog drives, it interfaces with older current and voltage regulators instead of serial communication networks. Speed ripple is minimized by the standard tacho quality, helping the controller receive stable motion data that matches actual shaft behavior. This combination supports applications that need dependable analog feedback, optional auxiliary drive takeoff, and straightforward integration with legacy motion-control equipment.
