Product Description:

The MAC071C-0-JS-4-C-095-B-0-WI520LV-S002 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive controllers, this motor converts current-controlled commands into proportional torque and speed for automated positioning tables, conveyors, and packaging lines. It comes without a blocking brake, so holding torque must be generated by the drive or by external mechanics when power is removed. This operating profile suits machines that require repeatable motion and steady speed control during normal production cycles.

Its frame follows the 071 size code, providing a compact envelope that eases installation in machinery with limited space. A centering diameter of 95 mm aligns the flange precisely to the mating gearbox or mount and helps keep radial runout low. The nominal operating speed is 2000 rpm, which matches common drive ratios used in automated equipment. Heat is dissipated through natural convection, eliminating fans and reducing maintenance while still supporting continuous duty within the stated thermal limits. The armature uses the JS winding code, which corresponds to electrical values that allow the analog amplifier to reach rated current without saturation.

Power is supplied through a connector mounted on side B, allowing cable routing opposite the driven shaft and reducing the risk of flex fatigue. Tachogenerator feedback delivers 3 V/1000 rpm, giving the amplifier a proportional velocity signal for smooth low-speed regulation. For position tasks, an incremental encoder provides fine step resolution when used with external counting electronics. The mechanical package length is C, which balances rotor inertia and torque density so the axis can accelerate quickly without excessive overshoot. This layout also helps keep the motor compact enough for installation where available mounting space is limited.
