Product Description:

The MAC063A-0-ES-4-C/095-B-1/WI522LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for analog drive systems where continuous closed-loop speed and position control are required. Within automated machinery, this unit converts electrical commands from the drive into controlled rotary motion, allowing precise actuation of tool heads, indexing tables, or conveyor sections while remaining compatible with legacy analog controllers used on many production lines.

The integrated blocking brake delivers 3 Nm of holding torque so the shaft remains fixed when power is removed, which is useful on vertical or load-sensitive axes. A centering diameter of 95 mm provides the pilot interface for accurate alignment to gearboxes or mounting flanges. Heat produced by copper losses is dissipated through natural convection, so no auxiliary blower or liquid circuit is necessary. The frame code 063 indicates a moderate stator size that balances inertia with torque density for mid-range servo tasks. Under rated excitation, the rotor reaches 3500 rpm, supplying a speed range suitable for both continuous duty and rapid indexing cycles without exceeding standard bearing limits.

Power conductors exit through a connector on side B, allowing cable routing away from the driven load and reducing bending stress during axis movement. The built-in tachogenerator outputs 1.5 V/1000 rpm, giving the analog drive a proportional feedback signal for speed stabilization, while winding code ES indicates the copper fill and impedance values associated with current demand and thermal behavior. For higher-resolution control loops, the motor supports an incremental or absolute encoder with tacho feedback, so retrofit applications can use digital position tracking without replacing the mechanical package.
