Product Description:

The MAC090C-0-KD-4-C/110-B-0 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a three-phase rotary actuator intended for analog drive assemblies where speed and position are regulated by external control hardware instead of integrated digital communication. In automated production lines, it supplies closed-loop motion for tooling stations, pick-and-place axes, and conveyor sections. The motor is suited to applications that need repeatable rotation from a compact servo package with integrated feedback functions.

The motor’s nominal shaft velocity is 1500 rpm, which gives the connected drive a moderate operating speed for indexing and transport duties. Accurate mechanical alignment is supported by a centering diameter of 110 mm, allowing the housing to seat squarely in matching machine brackets. Heat is removed through natural convection, so no separate blower or liquid-cooling circuit is required when cabinet airflow is adequate. Main power enters through a connector on side B of the stator end cap, which helps with cable routing when the motor is installed near the right side of a machine frame. Electromagnetic behavior is set by the KD winding, allowing the matching analog drive to apply the proper current characteristics.

This model is supplied without a blocking brake, so any holding force during power loss must come from an external clamp or from the driven mechanism. Speed and position information reach the controller through incremental or absolute encoder feedback, supporting low-speed regulation and position monitoring during operation. The tachogenerator produces 3 V/1000 rpm, giving the drive a predictable voltage signal for velocity feedback. Its output follows a standard tacho quality tolerance, which keeps the signal compatible with conventional analog loop filters. This arrangement uses separate amplification and feedback processing in the external drive.
