Product Description:

Bosch Rexroth Indramat’s MAC071C-0-JS-3-C/095-B/0 belongs to the MAC AC Servo Motors series and is intended for analog drives used in position and velocity control loops on industrial machinery. When paired with a compatible drive controller, the unit translates electrical command signals into mechanical rotation so that automated axes can follow process setpoints with limited lag and overshoot. This operating role makes the motor suitable for applications that need repeatable motion and stable speed regulation during continuous machine cycles.

The mechanical interface is centered on a 95 mm pilot diameter that aligns the frame to gearboxes or mounting plates. Frame designation 071 indicates a medium body cross-section, while winding code JS sets the motor’s electrical characteristics for matching drive operation. Under rated conditions, the rotor sustains a synchronous speed of 2000 rpm, giving steady operating velocity for processes such as indexing tables or feeders. Heat produced by copper losses is removed through natural convection, so no external blower or liquid cooling loop is required. A built-in DC tachogenerator outputs 3 V/1000 rpm, providing proportional feedback voltage that an analog drive can use to close the speed loop without an added feedback device.

The motor is supplied with no blocking brake, so applications that need static holding torque must rely on a mechanical clamp or drive-produced torque. Power conductors are routed through a connector on side B, which can simplify cable routing when nearby machine elements occupy the opposite side of the motor. The housing uses length code C, giving the unit a moderate installation depth while preserving the torque capacity expected from this frame size. Standard tacho quality and the second shaft end allow auxiliary transducers or monitoring devices to be added without changing the primary feedback arrangement.
