Product Description:
The MAC063D-0-JS-3-C/095-B-1 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it translates current-controlled commands from legacy amplifier cards into precise rotary motion for indexing tables, packaging axes, and other automation tasks. The motor includes a standard blocking brake and an internal tachogenerator, allowing the drive electronics to monitor speed and hold the shaft in position when power is removed.
The integrated brake delivers 3 Nm of static torque, which is sufficient to secure moderate loads during emergency stops or vertical idle periods. Shaft alignment with gearboxes or belt pulleys is aided by a 95 mm centering diameter that helps keep runout low. Heat produced by the windings is dissipated through natural convection, removing the need for forced-air or liquid cooling circuits. At its rated speed of 3500 rpm, the rotor provides velocity feedback through a tachogenerator that produces 1.5 V/1000 rpm. This proportional output allows analog controllers to scale speed-control loops linearly across the operating range. Power conductors enter through a connector on side B, simplifying cable routing in compact machine layouts. The tachogenerator uses the standard quality grade to support consistent calibration with compatible drive electronics.
This motor occupies the 063 frame class and has a D frame length, providing a longer magnetic stack for increased continuous torque while maintaining moderate inertia for rapid starts. The electromagnetic circuit uses winding code JS, pairing the unit with compatible MAC-series drives so current limits and back electromotive force remain within the required operating range. A second shaft end is available for an auxiliary encoder or mechanical coupling, allowing additional equipment to connect without an external shaft adapter. The dual-ended arrangement also provides installation flexibility when the primary shaft is dedicated to a gearbox, pulley, or driven machine component.
