Product Description:

The MAC071C-0-JS-4-C/095-B-0/WI524LX is an AC servo motor from Bosch Rexroth Indramat's MAC AC Servo Motors series. Designed for analog drives, it converts command voltages into controlled torque and speed for positioning tables, pick-and-place axes, and similar factory tasks. The 071 frame size with the medium housing length lets the motor fit mid-range load requirements while keeping the mounting style used across the MAC line. Its integrated feedback elements allow the connected amplifier to monitor motor behavior without requiring separate external sensing hardware.

Mechanical dimensions follow Indramat’s modular pattern. The centering pilot measures 95 mm, providing shaft alignment in standard IEC flanges, and the selected housing length is C, which balances inertia against overall depth. Thermal losses are removed by natural convection, so no fan or liquid circuit is required when the motor is mounted in free air. The JS winding is paired with a nominal speed of 2000 rpm, giving the drive a useful torque band without oversaturating the stator at typical analog bus voltages. The motor does not include a blocking brake, so static holding torque must be provided by the drive amplifier or external mechanics. Tacho feedback is supplied in standard quality to match legacy velocity loops.

Electrical interfaces are straightforward. Power enters through a connector on side B, which leaves the opposite face clear for encoder and tacho leads. The tacho generator delivers 3 V/1000 rpm, a level compatible with Indramat analog velocity cards, while position data is provided by an incremental encoder that uses the standard mounting arrangement of the series. The tachometer is rated Standard, providing repeatable speed signals without the tighter tolerances used on high-precision axes. This layout can simplify routing where the motor is mounted close to slides, guards, or other machine components.
