Product Description:

The MAC063D-0-JS-3-C/095-B-0-S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, it converts regulated current from a legacy servo amplifier into rotary motion that positions machinery with repeatable accuracy. Its mechanical frame, winding, and feedback elements work together to support closed-loop speed control on factory automation axes such as pick-and-place modules, packaging mandrels, and small gantries. Because the motor uses analog feedback rather than a digital network interface, the paired amplifier can adjust output continuously to maintain commanded speed under changing load.

The frame follows size code 063, which gives the motor a compact geometry for tight mechanical envelopes. The stator stack length is D, providing a longer active magnetic path than shorter versions of the same diameter and supporting higher continuous torque. A 95 mm centering bore aligns the flange on the machine face, and winding code JS indicates the resistance and inductance values used by compatible MAC-series drives. Under rated excitation, the rotor reaches a nominal speed of 3500 rpm, which suits indexing cycles that require fast acceleration and stable speed control. This layout is useful where installation space is limited but the axis still needs consistent rotary performance through frequent start-and-stop motion.

Tachogenerator feedback delivers 1.5 V per 1000 rpm, giving the drive a proportional voltage signal for analog velocity loops. Heat is removed by natural convection, so no external blower or liquid circuit is required. The motor is configured with tachofeedback and second shaft end, which allows an additional encoder or pulley to be coupled externally. Power enters through a connector on side B, simplifying cable routing along the motor body, and the motor does not include a blocking brake, so load holding during power-off must be handled by external mechanics or drive torque. In vertical or suspended applications, a separate holding method is needed to prevent the axis from drifting after power is removed.
