Product Description:

The MAC090B-0-PD-2-C/110-A-0/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is supplied as a motor for analog drives, meaning the shaft speed and torque are commanded by a voltage or current interface rather than a fully digital bus. In automated production lines, the unit closes the mechanical loop for feed axes, material-handling gantries, and compact transfer stations, delivering accurate position and velocity control wherever a direct analog reference is still used.

Bearing and mounting attributes begin with a centering shoulder of 110 mm, which aligns the motor housing to gearboxes or machine frames with minimal radial runout. Heat is removed passively through natural convection, so no external blower or liquid circuit is required, and unobstructed airflow around the frame keeps winding temperatures within limits. Rotor position is monitored by integrated tacho feedback, allowing the analog drive to measure real-time speed for closed-loop regulation. The magnetic design supports a nominal shaft speed of 1500 rpm, matching common 50 Hz machine tool feed rates. Power conductors exit through a connector on side A, simplifying cable routing when the motor is installed with its flange facing the machine.

Additional parameters describe how the motor integrates with the drive electronics. The tacho generator produces 3 V/1000 rpm, giving a clean linear voltage that the controller converts directly into speed error signals. Stator windings follow code PD, so the resistance and inductance match legacy MAC amplifiers without retuning. Mechanical retention is left to the drivetrain because the unit is supplied without a blocking brake, so vertical axes require an external holding device. For applications that do not demand high-precision velocity ripple, the motor uses standard tacho quality, which suits general-purpose motion profiles.
