Product Description:

The MAC025B-0-ZS-4-E/040-A-1/WI668LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts commanded current into controlled torque and speed, allowing machine axes to position accurately, follow velocity profiles, or hold a load at rest. Because the control electronics are located in the separate drive, the motor serves as the rotary output element while current and velocity regulation are handled externally. Its compact format suits packaging lines, small handling modules, and other automation stations where responsive servo motion is needed without a large motor footprint.

Cooling is handled by natural convection, so heat leaves through the housing without separate fans or liquid circuits. This arrangement keeps the motor layout simple, but the installation still needs enough open space around the frame for air to circulate freely. Power is carried through a single cable that exits on a connector on side A, which keeps wiring paths straightforward and separates the motor lead from the feedback connection. The motor uses motor length 025 and motor size B, giving it a short magnetic stack and the flange and shaft proportions associated with this frame. A standard blocking brake holds the shaft when drive power is removed, which helps prevent drift on vertical axes or loads with stored inertia.

The electrical interface is arranged for tacho feedback with an incremental or absolute encoder, so the motor can support both speed sensing and position-related feedback methods. For incremental applications, it already includes an incremental encoder with standard mounting, which keeps the feedback package simple and consistent with common MAC installations. This combination gives the external drive the shaft information needed for stable low-speed control, repeatable positioning, and monitoring during changes in load. It also allows the motor to fit applications that require compact servo hardware with integrated feedback and brake-assisted holding.
