Product Description:

The MAC025A-0-WS-3-E/040-C-0/S001 is an AC servo motor built by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drives, it supplies rotary output for positioning and speed control on compact machine axes, conveyor metering stations, and similar automation equipment. The motor interfaces with legacy drive electronics that use voltage and current reference signals, allowing it to operate in existing control architectures without major changes to the surrounding system. In service, it converts drive commands into controlled shaft motion for applications that require repeatable response in a compact mechanical package.

Its electrical design uses winding code WS, which matches the coil impedance and voltage constants to compatible analog amplifiers. Frame dimensions follow the MAC family naming pattern, with a motor size of 025 and a motor length of A, so the housing remains suitable for space-restricted installations. This compact format limits shaft center height and stack depth while preserving the operating characteristics expected from the series. Heat is dissipated by natural convection, which removes the need for external blowers and keeps cabinet layout simple. For motion feedback, the housing provides tacho feedback signals that an analog drive can read directly for closed-loop speed regulation. The rotor is coupled to a tacho generator, so the speed signal is produced internally without requiring a separate external feedback device.

This configuration has no blocking brake, so holding or stopping torque must be supplied by the drive or by a downstream gearbox when the axis is at rest. Because the unit does not include a mechanical holding device, vertical or suspended loads may require external restraint when power is removed. The motor also includes a second shaft end, which can be used for an auxiliary encoder, a brake, or another mechanical coupling when the application requires it. That added shaft interface also allows diagnostic access or auxiliary motion components without disturbing the primary drive connection.
