Product Description:

The MAC093B-0-JS-4-C/110-B-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it converts proportional command voltages into precise rotary motion for positioning tables, packaging machines, and similar automation stages. Integrated motor feedback allows the connected amplifier to monitor motion while the motor remains a compact actuator for general-purpose axis control. That arrangement suits machinery that depends on stable speed regulation and repeatable positioning during continuous production cycles.

The flange has a centering diameter of 110 mm, which sets the reference plane for accurate shaft alignment against gearboxes or load couplings. Heat is removed by natural convection, so the motor can be installed without external fans when ambient airflow remains unobstructed. Because cooling is passive, the housing operates without auxiliary blowers. Frame size 093 with length designation B gives the motor its overall footprint and rotor inertia, while winding code JS matches the copper fill and magnetic circuit used with current-controlled analog amplifiers. Under rated conditions, the rotor reaches 3000 rpm, a speed that suits many servo applications using analog control loops.

Power conductors exit through a connector on side B, permitting straight cable drops in cabinets where the shaft faces forward. Tachogenerator output is scaled at 3 V/1000 rpm, and the standard tacho quality provides a linear velocity signal for older analog regulators. Position data is provided by an incremental encoder with standard mounting, and the feedback wiring can accommodate optional absolute tracks when required by the control system. The motor has no blocking brake, so applications that need static holding torque must rely on external mechanical locks or drive torque. The tachogenerator supports speed feedback, while the encoder supplies position information to the control system.
