Product Description:

The MAC071C-0-JS-3-C/095-B-0/8 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This model is intended for closed-loop axis control in transfer lines, material handling stations, and general automation cells that still rely on analog velocity and torque commands. By supplying controllable electromagnetic torque across a wide speed range, the motor serves as the actuating element between the drive amplifier and the mechanical load, supporting repeatable motion profiles and accurate positioning. Its design suits installations that need dependable performance without the additional complexity of digital fieldbus interfaces.

Its winding code JS identifies the stator conductor layout and resistance characteristics selected for medium-inertia loads. The centering shoulder diameter of 95 mm provides the piloting surface for rigid flange mounting and alignment with gearboxes or direct-drive assemblies. Under rated conditions, the rotor turns at 2000 min⁻¹, offering a balance between torque density and servo responsiveness. Heat is removed solely by natural convection, so airflow around the housing must remain unobstructed during continuous duty. The motor has no blocking brake, so position holding during power-off must be provided by the drive or by external mechanics. The feedback arrangement combines tacho feedback and a second shaft end, delivering an analog velocity signal while leaving the opposite side available for an additional encoder or a mechanical coupler.

Electrical power is routed through a keyed connector mounted on side B, which can simplify cable runs in cabinets where the drive is installed to the right of the motor. The frame code 071 and body length C give the motor a compact envelope that suits tight axis spacing on handling robots or packaging machinery. Velocity linearity is maintained by a standard quality tacho generator that yields 3 V/1000 min⁻¹, enabling analog control loops to measure speed without additional scaling hardware. This layout supports applications that need straightforward analog feedback and a compact motor housing.
