Product Description:

The MAC063B-0-JS-1-C/095-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts command voltages from a drive amplifier into controlled mechanical rotation for positioning and speed-regulated axes in automated assembly cells, pick-and-place heads, and light machining stations. Its compact frame and standardized mounting pattern let machine builders install the motor directly onto linear slides or index tables, while the built-in commutation sensors keep the shaft synchronized with the reference signal.

The motor is equipped with a blocking brake that can hold up to 3 Nm of static torque, so vertical or load-bearing axes remain stationary when power is removed. A centering shoulder diameter of 95 mm aligns the flange against the mating machine surface and maintains concentricity during high-speed operation. Heat generated in the stator is removed by natural convection, so no external blower or liquid circuit is required. The winding set identified by code JS is rated for a nominal speed of 6000 min⁻¹, allowing rapid traverses in short-stroke mechanisms. Power conductors reach the terminals through a connector on side A, which eases cable routing in tight spaces. The overall axial length conforms to length code B, giving the motor a predictable envelope when paired with gearheads or belt drives.

Position data are returned to the drive through incremental encoder feedback, enabling fine velocity loops and electronic gearing functions. The frame size is 063, indicating a moderate stator diameter that balances torque density with inertia for quick start-stop cycles. For speed verification in analog control schemes, the integrated tacho generator produces 1.5 V/1000 min⁻¹, supplying a proportional voltage that the drive amplifier interprets as actual shaft speed.
