Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI651LV/S001 is an AC servo motor built by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. As a motor for analog drive systems, it converts commanded current into rotary motion for positioning or speed-regulated axes in industrial machinery. It is suited to compact automation axes that need repeatable motion and smooth speed control during normal operation.

The unit relies on natural convection cooling, so heat is dissipated through the housing without forced air or liquid circuits, which simplifies installation and minimizes maintenance points. Power conductors enter through a connector on side B, allowing cabling to be routed along the rear of the machine frame and keeping the encoder end clear for feedback wiring. Because it is supplied without a blocking brake, holding torque must be provided by the drive or an external clamp whenever the axis has to remain stationary after power is removed. The rotor-stack designation 025 indicates the active magnetic length and suits short-stroke, low-inertia applications. Its frame size C gives a compact flange diameter that suits indexing tables and small pick-and-place modules where space is limited.

Position and velocity signals are generated by an incremental encoder with standard mounting, which attaches directly to the rear shaft and delivers quadrature pulses to the controller. For retrofit cases, the feedback port can also accept tacho feedback, incremental encoder, or absolute encoder options, giving flexibility in closed-loop resolution and direction sensing. As a motor for analog drives, the stator windings are tuned for current-controlled amplifiers that output continuous analog command signals rather than digital PWM. Its membership in the MAC AC Servo Motors series supports mechanical interchangeability with other frame sizes in that family across multi-axis equipment.
