Product Description:

The MAC092B-0-QD-3-C/095-A-1 servo motor is built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is used for closed-loop axis control with analog drive amplifiers, where consistent speed and torque regulation support material handling, packaging, and machine-tool automation. By combining magnetic excitation with tachometer feedback, the motor returns real-time velocity information to its drive. This feedback allows the amplifier to correct speed deviations as operating loads change without requiring a separate encoder for the primary control loop.

The mechanical interface has a 95 mm centering diameter, allowing the flange to align precisely with compatible Rexroth machine frames. Thermal energy is removed through natural convection, so the motor does not require a forced-air or liquid-cooling circuit. A standard blocking brake engages when the drive is disabled, helping hold the shaft and prevent load drift on vertical axes. Power enters through a connector on side A, permitting cable routing away from components at the opposite end of the housing. Motion feedback is supplied through tachometer feedback and a second shaft end. This arrangement provides an analog velocity signal while retaining a mechanical takeoff that can connect to an auxiliary device, such as a belt encoder or handwheel.

As a motor for analog drives, the unit is configured for the voltage and current control loops used by compatible Indramat drive amplifiers. The internal tachometer has standard tacho quality, providing a linear voltage-to-speed relationship that works with the calibration values used by MAC drive cards. The returned signal gives the amplifier a continuous indication of shaft velocity, supporting stable regulation during acceleration, steady operation, and deceleration. The second shaft end also permits a separate mechanical device to be connected when an application requires an additional motion reference or manually operated interface. The side A power connection helps keep the main cable path separate from equipment attached to that second shaft end, reducing interference between the electrical routing and auxiliary mechanical components.
