Product Description:

Bosch Rexroth Indramat manufactures the MAC071A-0-HS-4-C/095-B-1/WI517LV, an AC servo motor in the MAC AC Servo Motors series. Intended for analog drives, it converts voltage setpoints from legacy velocity or torque controllers into precise mechanical rotation for automated axes. By supplying controlled torque over a broad speed range, the unit supports pick-and-place gantries, feeders, and print cylinders that depend on accurate registration from cycle to cycle. That arrangement is useful in retrofit equipment where existing analog amplifiers remain in service and the machine still requires repeatable axis motion.

This model uses frame size 071 and length A, giving a compact footprint that fits mid-frame machinery while still accommodating the required electromagnetic cross section. A centering pilot of 95 mm simplifies concentric alignment with reducers and mounting plates, which helps reduce radial runout during operation. The stator winding identified by code HS has low electrical time constants that help the drive produce high dynamic torque during acceleration and correction. Under rated conditions, the shaft can reach 2000 rpm, a speed suited for direct coupling to lead screws or belt pulleys. Heat is removed by natural convection, so no auxiliary fan or liquid circuit is needed when ambient air can circulate freely around the housing.

An integrated blocking brake applies 3 Nm of static torque to lock the shaft when drive enable is released. The motor includes a standard-quality tachogenerator with an output of 3 V/1000 rpm at nominal speed, and an incremental encoder on the same shaft supplies position pulses for closed-loop control. Three-phase power is routed through a connector on side B, which keeps wiring away from the machine front and can simplify cable routing in enclosed assemblies. The combination of brake, speed feedback, and position pulses supports stable regulation in legacy analog motion systems.
