Product Description:

The MAC025A-0-WS-3-E/040-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts commanded voltage and current into controlled torque and speed for light-duty positioning stages, small conveyors, and auxiliary axes in automated machinery. Its compact frame, electrical winding, and integrated holding capability support rapid response and consistent repeatability in space-limited machine layouts.

This model includes a standard blocking brake, so the shaft remains fixed when power is removed and vertical loads cannot settle. Heat is removed through natural convection, eliminating the need for an external fan or liquid cooling circuit. Rotor information is provided through tacho feedback with a second shaft end, giving the drive accurate velocity data while providing an auxiliary shaft stub for an additional encoder or mechanical coupling. The motor has a frame size of 025, which supports a compact mounting footprint for smaller automated axes. Its frame length is A, providing a short housing suitable for installations with limited axial clearance.

Power is delivered through a connector on side B, which helps separate the power cable from feedback wiring and supports orderly cable routing around the motor housing. The electrical characteristics follow winding code WS, which establishes resistance and inductance values compatible with the current regulation of the connected analog drive. A 40 mm centering diameter aligns the motor accurately with the mounting surface and connected machinery. The motor can operate without digital fieldbus communication because command processing and closed-loop regulation are handled by the paired analog drive. The second shaft end can support an auxiliary feedback device when the application requires additional position information beyond the integrated velocity signal.
