Product Description:

The MAC090C-0-GD-4-C/110-A-0/WI533/S001 is manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This motor is installed on analog drive axes where velocity and torque are regulated by external amplifiers in packaging, printing, and material-handling equipment. By receiving a current-controlled supply from the drive, it converts electrical commands into mechanical rotation that positions tooling or conveyors with repeatable accuracy in automated production lines.

The motor is supplied without a blocking brake, so holding torque must be delivered by the drive or an external mechanical lock when power is removed. A centering boss of 110 mm aligns the flange precisely against machine housings to minimize radial runout. Heat generated in the stator is carried away by natural convection, eliminating fans and reducing maintenance where airborne fibers or dust are present. Rotor speed information is captured through a tacho feedback channel, which supplies the velocity signal used by the analog control loop. The stator terminals are reached through a connector on side A, which keeps power cabling on the same face as the mounting screws. The GD winding code identifies resistance and inductance values that support compatibility with designated analog amplifiers.

As a motor for analog drives, the unit expects proportional current commands rather than digital fieldbus messages, allowing it to operate in legacy control cabinets that still use voltage-controlled servo cards. Position capture can be expanded by mounting an incremental encoder in the standard interface pocket, providing pulse trains that the drive counts for fine positioning at low speed. The sensor chain has a standard tacho quality grade, indicating that the tachogenerator meets baseline linearity and ripple limits required for analog velocity loops in most packaging and converting machinery.
