Product Description:

The MAC071C-0-JS-4-C/095-A-2/DI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into precise rotary motion for position- or velocity-controlled axes in automated machinery. The unit operates in closed-loop mode, with its internal tachometer and encoder supplying speed and position data to the drive controller for stable regulation. That arrangement supports repeatable indexing in packaging stations, pick-and-place gantries, and printing cylinders where smooth response and accurate feedback are required. This makes the motor suitable for applications that must start, stop, and correct speed quickly under changing loads.

The motor uses frame size 071, which establishes the outside diameter and supports installation alongside matching couplings and gearboxes. Length code C indicates a longer active lamination stack that increases continuous torque without changing the basic mounting footprint. A centering flange of 95 mm positions the housing accurately on the machine face and helps maintain alignment during installation. The rated speed is 2000 rpm, and winding code JS identifies the electrical characteristics used by a compatible analog drive. This layout helps keep shaft alignment consistent when the motor is coupled directly to a pulley, gearbox, or other driven element.

Load holding during power loss is provided by a heavy-duty blocking brake with a static torque of 6.5 Nm, which helps prevent back-driving on vertical or high-inertia axes. Heat is removed through natural convection, so the motor does not require external fans or liquid-cooling lines. A tachometer output of 3 V/1000 rpm, together with the encoder mounted on shock-damped supports, supplies the feedback signals needed for stable velocity and position control. Power conductors exit through a connector on side A, which can simplify cable routing when the motor is mounted close to adjacent machine components.
