Product Description:

The MAC090B-0-PD-4-C/110-A-WI518LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is engineered for closed-loop positioning and velocity control in automated machines where repeatable motion is required for material handling, converting, or assembly operations. Internal electromagnetic fields synchronize continuous rotation with drive commands, allowing the motor shaft to follow reference signals accurately in industrial environments.

The flange has a centering diameter of 110 mm, so the motor can be aligned precisely inside gearboxes or mounting plates without supplementary adapters. Heat is released through natural convection, meaning ambient air passing over the housing removes thermal losses without fans or coolant plumbing. At a nominal speed of 1500 rpm, the electromagnetic system reaches its rated balance between torque output and thermal rise. Power and feedback conductors are routed through a connector on side A, simplifying cable routing by keeping both terminations on one face of the stator. The unit is classified as a motor for analog drives, making it compatible with conventional analog servo amplifier platforms used in process machinery.

Velocity information is generated by tacho feedback with an incremental or absolute encoder mounted on the rear shaft extension, allowing the drive to detect speed changes almost instantaneously. The sensing hardware provides standard-quality tacho performance, offering an accuracy level suited to general industrial positioning rather than submicron applications. Signal amplitude is fixed at 3 V per 1000 rpm, so the controller receives a linear voltage proportional to shaft speed across the working range. Electromagnetic characteristics are established by the PD winding, a coil arrangement with resistance, inductance, and torque constant values appropriate for this motor frame. These electrical characteristics allow conventional analog servo amplifiers to regulate motor current throughout positioning and speed-control cycles.
