Product Description:

The MAC090B-0-JD-2-F/110-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Intended for positioning tables, tool heads, and other motion axes in automated equipment, the unit converts drive current into controlled rotation with the fast response needed for repeated starts, stops, and speed changes during continuous machine operation. By combining a permanent-magnet rotor with electronic commutation, it delivers steady torque output and responsive speed regulation in production lines and material-handling stations.

The motor mounts against a machine frame with a centering flange that measures 110 mm in diameter, and this size helps control radial runout between the motor shaft and the driven element. Heat is removed through natural convection, a cooling method that depends on ambient airflow and supports fanless operation so no auxiliary fan is required. Rotor speed feedback is provided by integrated tacho feedback, which generates an analog voltage proportional to rpm for closed-loop velocity control. The tacho is graded for increased smooth-running quality, which helps reduce speed ripple during light-load motion. Power conductors exit through a connector on side A, which can simplify cable routing when the motor is installed against a right-hand machine wall.

For safety and load holding, the design relies on external mechanics because there is no blocking brake integrated into the housing. When paired with an analog amplifier, the motor operates as a motor for analog drives, allowing proportional control of torque or speed without digital servo loops. The pilot flange helps the housing seat accurately before the mounting bolts are tightened, which supports shaft alignment and stable coupling to the driven machine element on compact axis assemblies.
