Product Description:

The MAC071C-0-JS-4-C-095-A-0-WI504LV-S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive controllers, it translates commanded current into precise rotary motion for feed axes, pick-and-place heads, and other position-critical mechanisms used in automated production lines. Its integrated feedback arrangement supports stable speed regulation and position tracking during repeated motion cycles. This operating concept is common in packaging, transfer, and handling systems where the motor must respond smoothly to changing commands while maintaining repeatable movement.

The motor reaches a nominal shaft speed of 2000 rpm, which supports stable motion profiles in typical servo applications. Heat generated in the stator is removed by natural convection, so no external blower or liquid circuit is necessary. Cooling by natural convection also keeps installation simple because no auxiliary fan wiring or airflow ducting is required. A centering diameter of 95 mm helps align the flange with mating machine surfaces. Torque is transmitted through a DIN 6885 keyway that accepts standard keyed hubs, and power conductors exit through a connector on side A to simplify cable routing when the shaft faces the workstation. Because a blocking brake is not included, static holding torque must be supplied by the drive or by an external clamp. The motor uses length code C for its lamination stack, which indicates the active motor length used in this housing size.

The built-in tachogenerator provides 3 V/1000 rpm, giving the drive an analog speed signal during operation. A standard-mounted incremental encoder supplies position data for closed-loop control, and winding code JS identifies the electrical configuration used with compatible MAC analog amplifiers. Frame designation 071 corresponds to the motor’s outer diameter and bolt circle, helping it fit the intended mounting interface. This combination lets the drive monitor both velocity and rotor position through integrated feedback devices. Standard tachogenerator components are included in the assembly, and the feedback hardware is arranged within the motor housing to keep external installation requirements straightforward.
