Product Description:

Bosch Rexroth Indramat builds the MAC093B-0-JS-4-C/130-A-1/WI524LV for its MAC AC Servo Motors series. This AC servo motor, with size 093 and length code B, suits analog drive systems where torque and velocity loops are handled in the controller. In automated machinery, it converts electrical energy into controlled rotary motion so axes follow precise speed or position commands. The integrated tachogenerator and encoder provide real-time feedback to the drive, supporting stable regulation in packaging, printing, and material-handling lines. This arrangement is useful for axes that require repeatable speed control during frequent starts, stops, and positioning changes.

The motor uses winding code JS, which sets resistance and inductance for medium-power operation. At a nominal speed of 3000 rpm, the rotor delivers steady velocity that aligns with common analog controller requirements. A 130 mm centering diameter positions the motor accurately against gearboxes and helps keep runout low. Heat is removed through natural convection, so the housing should remain in free air during operation. Power arrives through a connector on side A, which simplifies cable routing. The feedback system combines tacho feedback with encoder signals to provide both speed and position data.

Mechanical holding is provided by a standard blocking brake, which clamps the shaft when the drive is disabled and helps prevent load drift on vertical axes. Speed feedback is produced at 3 V/1000 rpm, a level that balances signal strength and noise immunity for analog velocity loops. As a motor for analog drives, it can pair directly with legacy controllers that modulate voltage rather than exchange digital fieldbus data. Position reference comes from an incremental encoder with standard mounting, which supports straightforward installation without special brackets. The tacho quality is standard, and the B-length housing keeps overall depth moderate for tight machine frames.
