Product Description:

The MAC063A-0-ES-4-F/095-A-0/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for analog drives and translates ±10 V velocity or current commands into controlled rotary motion, delivering closed-loop performance for indexing tables, small gantries, and feed axes. Typical uses include packaging equipment, compact material-handling axes, and other machines that rely on repeatable starts, stops, and speed regulation through frequent duty cycles. By combining a permanent-magnet rotor with electronic commutation, the unit supplies rapid torque response while keeping maintenance demands low in continuous industrial service.

With a centering diameter of 95 mm, the motor seats accurately against mounting pilots to maintain shaft concentricity. The nominal speed capability is 3500 rpm, giving adequate headroom for fast positioning cycles. Frame size 063 and build length code A keep the body compact where installation depth is limited. This layout helps preserve mounting space in tightly packed axis assemblies. The ES winding uses electrical constants selected to balance torque production with thermal limits. Because a blocking brake is not present, external holding devices are required when vertical loads are involved.

Thermal management relies on natural convection, which keeps audible noise low and avoids added cooling hardware. The power circuit exits through a connector on side A, so cabling can run parallel to the machine bed without added bends. A tacho generator rated at 1.5 V/1000 rpm feeds the analog drive with velocity feedback, and the tacho is tuned for increased smooth run quality to minimize speed ripple at low speeds. Position data is supplied by an incremental encoder mounted in the standard location, and the feedback arrangement also supports an absolute encoder when the control system requires startup position retention.
