Product Description:

The MAC025A-0-WS-4-E/040-A-1/WI664LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This compact rotary unit delivers controlled torque and speed for axes driven by analog velocity or position commands. In automated assembly lines, packaging cells, and printing equipment, it converts current from a matching amplifier into precisely regulated motion so the control system can synchronize tooling with conveyor flow and cycle timing. Its compact format also helps the motor fit into tightly spaced machine sections where responsive motion and stable feedback are both required.

The stator winding uses the WS code, which indicates the electrical characteristics used by the matching amplifier. The motor has a length code of 025 and a size code of A, giving it a short stack that helps keep rotor inertia low for fast response. Heat produced by copper losses is removed through natural convection, so no external blower is required and surrounding airflow remains simple. Power leads exit through a connector on side A, which directs cabling toward the drive panel and helps maintain orderly routing inside compact enclosures. This layout supports installations where cable bends must stay controlled near the motor body and adjacent hardware leaves little free space.

Position feedback is provided by an incremental encoder with standard mounting, and its square-wave signals allow an analog controller to regulate speed while maintaining accurate position tracking. For applications that also require speed verification, the motor uses tacho feedback with an incremental or absolute encoder, which supports compatibility with legacy drive racks and mixed feedback architectures. Shaft holding torque during downtime is supplied by a standard blocking brake that engages automatically when the drive is disabled. As a motor for analog drives, the unit provides the interface levels and reference voltages expected by earlier MAC amplifiers. This makes it suitable for systems that need updated motion performance while continuing to operate with established analog control hardware.
