Product Description:

Bosch Rexroth Indramat manufactures the MAC093B-0-JS-4-C/110-A-0/WI522LV, a motor in the MAC AC Servo Motors series that interfaces with analog drive controllers to position and propel machine axes in automated production cells. By transforming the amplifier’s current commands into rotational motion, the unit supplies continuous, feedback-governed torque. This operating role suits packaging stations, material-handling gantries, and similar equipment where coordinated motion is required. Because the motor is intended for analog drive systems, command processing remains in the external controller while the motor provides the electromechanical output at the axis.

The motor’s centering shoulder measures 110 mm, allowing direct seating in precision spigots without additional sleeves. Heat is removed through natural convection, so no external blower or liquid circuit is required. Stator geometry identified as size 093 pairs with length code B to balance torque density against overall mass. The windings use the JS winding code, which corresponds to resistance and inductance values that match the current limits of MAC-compatible drive modules. For speed feedback, the integrated tacho generator outputs 3 V/1000 rpm, enabling the controller to compare actual shaft speed with the commanded profile and correct for load disturbances in real time.

The shaft reaches a nominal speed of 3000 rpm, supporting applications that need rapid indexing without mechanical gear multiplication. Power and signal leads exit through a right-angle connector on side A, which helps route cables away from moving machine members. The motor is supplied without a blocking brake, so installations that need static holding torque must rely on external clamps or the drive’s regenerative torque mode during power loss. Position data for fine interpolation is obtained from the co-mounted incremental encoder, which shares the same mechanical reference as the tacho so the control loop receives consistent velocity and position information.
