Product Description:

The MAC025B-0-ZS-4-E/040-A-1/WI668LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a drive element for closed-loop industrial axes, it converts torque and speed commands from analog controllers directly into rotary motion. The motor fits compact handling modules, printing stations, and assembly cells where precise velocity tracking and low inertia response are required. Its compact format also suits machine sections where available mounting space is limited and moving mass must be kept low.

Its thermal path relies on natural convection, so airflow across the housing removes heat without auxiliary fans. An integrated blocking brake secures the load when power is removed, allowing vertical or intermittent-duty shafts to hold position. The power leads exit through a connector on side A, which simplifies cable routing along linear slides mounted on the same face. Mechanical dimensions follow length code 025 and frame size B, giving a short body that reduces installed depth while maintaining sufficient stator volume for continuous torque. The short housing can also leave more room for couplings, guards, or adjacent machine components in shallow assemblies.

For commutation and velocity control, the rotor position is reported by an incremental encoder. The same sensing path can include tacho feedback to supply an analog speed signal to legacy drive cards. This feedback arrangement suits its role as a motor for analog drives, permitting compatibility with earlier Rexroth transconductance amplifiers. The encoder signals, brake circuit, and single-sided power connection support a straightforward electrical interface for compact multi-axis equipment, and they allow the motor to be connected without separate external feedback adapters.
