Product Description:

The MAC025A-0-WS-4-E/040-A-0/WI652LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It functions as an electromechanical actuator that turns analog velocity and torque commands from a drive into precise rotary motion for industrial automation lines, filling machines, and compact pick-and-place stations. The unit is suited for motion tasks that require steady speed control and accurate rotary response in a compact installation space.

The electromagnetic circuit uses winding code WS, which sets the motor’s voltage constant and current density so it can be matched to the correct amplifier. Heat produced by copper losses is removed through natural convection, so no external blower or liquid jacket is required. The mechanical build has no blocking brake, so holding torque during power-off must come from the drive or an external clamp. Power conductors enter through a connector on side A, which places the cable exit on the gearbox side of many right-angle installations and helps reduce bending stress on the wiring. The stator iron length code 025 indicates the active stack height and the continuous torque capability for this frame.

Physical form factor A identifies the housing diameter, allowing the motor to fit low-profile machines without reworking mounting plates. For velocity feedback and commutation, the unit supports an incremental or absolute encoder with tachofeedback. Its default position sensor is an incremental encoder with standard mounting, which supplies speed data and position pulses for indexing tasks. Because it is a motor for analog drives, command signals are delivered as ±10 V references rather than through a fieldbus. This makes the model suitable for use with compatible MAC controllers and other analog servo amplifiers.
