Product Description:

Bosch Rexroth Indramat built the MAC093B-0-JS-4-C/110-A-0/WI522LX for closed-loop motion axes that use analog drive amplifiers in the MAC AC Servo Motors series. As a servo motor in that series, it converts electrical input into controlled torque and speed for positioning tasks on machine tools, printing lines, and handling modules. It is intended to provide steady torque under drive command, enabling precise movement without the need for intermediate mechanical gearing. This makes it suitable for applications that require repeatable starts, stops, and speed changes during normal production cycles.

The mechanical interface uses a 110 mm centering diameter, allowing the housing to align accurately with gearboxes or flanges without additional sleeves. Heat is removed by natural convection, so the motor depends on ambient airflow and surface radiation rather than forced fans. Rated speed reaches 3000 rpm, giving process equipment a balance between cycle time and positional resolution when paired with the appropriate drive. Power and signal leads exit through a connector on side A, making cable routing predictable inside tight cabinets. The motor has no blocking brake, so holding torque during power-off must be provided by external clamps or drive torque.

The internal winding is coded JS, which matches the electrical characteristics expected by compatible MAC drives for current regulation. For velocity feedback, the built-in tacho generator outputs 3 V/1000 rpm, which the drive uses to support stable speed control at low revolutions. In addition, the resolver housing accepts incremental or absolute encoder feedback, allowing higher-resolution position loops when required. Its feedback arrangement supports both basic speed regulation and more detailed position monitoring, depending on the installed feedback option. The motor belongs to frame size 093, and its length designation B gives it moderate rotor inertia that supports quick acceleration while keeping bearing loads within normal operating limits.
