Product Description:

The MAC071C-0-JS-2-C/095-B-0 is an AC servo motor built by Bosch Rexroth Indramat for use with analog drive amplifiers. It belongs to the MAC AC Servo Motors series and provides closed-loop speed control in automated machinery where consistent torque and precise velocity are required. The motor is well suited to equipment that still relies on analog command structures rather than digital network control. By combining integrated speed feedback with a permanent-magnet rotor, the unit supports stable motor regulation while keeping a compact form factor for multi-axis industrial installations.

The motor uses a centering diameter of 95 mm, allowing direct seating in standard mounting flanges without additional alignment bushings. That fit helps maintain concentric alignment between the motor and the driven mechanism. Heat produced by the stator dissipates through natural convection, which removes the need for external fans or liquid cooling hardware. Speed information is returned through integral tacho feedback, supporting proportional voltage monitoring at the drive. The rated operating speed reaches 2000 rpm, making it suitable for moderate-speed axes that require smooth acceleration and steady velocity. The motor uses the JS winding code, which sets the electrical values expected by compatible analog amplifiers.

Power enters the stator through a connector on side B, which can simplify cable routing when several motors follow the same cabinet path. This orientation can also reduce sharp cable bends when the motor is mounted close to neighboring axes or enclosure walls. The built-in tachogenerator outputs 3 V/1000 rpm, giving the drive a linear reference for velocity regulation. The motor has no blocking brake, so holding force must be provided externally when the axis is de-energized. Vertical or suspended loads therefore need a separate holding method when power is removed. The motor is in size 071, and the C-length housing extends the active stack to raise continuous power without increasing flange width.
