Product Description:

The MAC071C-0-JS-4-C/095-B-0/WI634LX/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts controlled electrical power into precise rotary motion for positioning and speed regulation in automated machinery such as material-handling axes, indexing tables, and packaging stations. Its operating profile suits systems that use external analog control loops and need steady motor response during repeated starts, stops, and speed changes. That makes it suitable for retrofit equipment where a separate amplifier handles current control and the machine controller depends on predictable motor behavior rather than integrated digital electronics.

The centering shoulder is 95 mm, which helps align the motor on a gearbox or machine plate. Cooling relies on natural convection, so heat is removed without a separate fan and the outer surface must remain exposed to moving air. Under rated excitation, the rotor reaches 2000 rpm, a base speed suited to legacy analog velocity loops. The shaft uses a DIN 6885 keyway for positive torque transfer to standard hubs and couplings. Power conductors exit on side B, which can simplify cable routing when the cabinet is installed opposite the driven load.

The tachometer output is 3 V/1000 rpm, giving a voltage signal proportional to speed for analog regulation. An incremental encoder supplies finer position information for control systems that also monitor shaft movement. The winding code is JS, which corresponds to the electrical values used by compatible MAC drives, and the motor is built in size 071. The combination of tachometer feedback and incremental position sensing supports both speed monitoring and finer motion supervision without changing the motor's basic analog-drive role. Length designation C is used, and the motor has no blocking brake, so holding torque must be provided by the drive or by external mechanical hardware when the axis is stopped.
