Product Description:

The MAC071C-0-JS-2-F/095-B-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied as part of the MAC AC Servo Motors series. It is intended for analog drive systems where a dedicated velocity loop is closed through the internal tacho so the controller can regulate speed and torque during demanding automation routines. This arrangement allows the motor to support positioning and speed-controlled tasks without requiring a separate external speed sensor.

The motor seats against a mounting pilot that measures 95 mm in diameter, allowing accurate concentric alignment with gearboxes or machine frames. Heat is removed by natural convection, so no external blower or liquid circuit is required and the housing fins handle normal thermal dissipation. Rotor speed feedback is generated by the integrated tacho feedback device, giving the drive continuous velocity information for tight control. The mechanical design supports a rated shaft speed of 2000 rpm, fitting common gear ratios used in positioning axes. Power enters the stator windings through a connector on side B, which simplifies cable routing when the machine layout favors rear or right-hand entry.

The electromagnetic package uses winding code JS, which matches the resistance, inductance, and torque constant expected by analog amplifiers. A motor length of C adds active iron so the machine can reach the required torque without increasing the frame size. The tacho produces 3 V/1000 rpm, giving the controller a linear voltage reference that scales directly with rotor speed, and its sensor construction provides improved smooth running to help minimize velocity ripple at low speeds. Model size 071 keeps the overall diameter compact, and the unit is supplied without a blocking brake, so holding must be provided by drive torque or an external locking device when power is removed.
