Product Description:

The MAC093A-0-LS-3-C/110-A-0/S005 is produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Classified as a motor for analog drives, it is installed on machine axes that rely on analog velocity or torque commands rather than digital fieldbus control. Integrated tachogenerator feedback on the second shaft end provides a speed-proportional voltage so the legacy drive can close its loop without additional sensors. This makes the unit suitable for retrofits and for the continued operation of mature automation lines.

The electromagnetic design is identified by winding code LS, which indicates the motor’s resistance and inductance values for proper matching to the companion drive. A nominal speed of 4000 rpm allows high surface velocities on moderate gear ratios while remaining within the continuous torque envelope. Heat produced by copper losses is removed through natural convection, so no external blower or liquid circuit is required. The housing includes a centering pilot of 110 mm that aligns the stator precisely to the machine frame and helps preserve concentricity. Power is routed through a single-phase screened cable that terminates on a connector on side A, placing the supply plug away from moving parts and simplifying cable routing.

Because the motor has no blocking brake, the application must rely on mechanical locks or servo holding current to maintain position when power is removed. The tachogenerator outputs 1.5 V/1000 rpm, giving the controller a linear speed signal for fine velocity regulation. The motor uses size 093, which fixes the flange and shaft dimensions, and motor length A, the shortest stack in this frame to minimize mass and inertia. Tacho quality is described as Standard, indicating normal accuracy for general-purpose motion tasks and compatibility with conventional analog velocity loops.
