Product Description:

The MAC090B-0-ND-4-C/110-A-0/WI516LV servo unit is built by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It converts drive-generated current into rotary motion for axes that require close coordination between commanded speed, measured feedback, and actual load movement. Used in packaging conveyors, pick-and-place arms, and infeed rollers, it serves as the electromechanical link between the drive controller and the moving load. Its integrated feedback signals allow the paired drive to correct speed changes caused by shifting process loads during operation. This arrangement supports repeatable motion on machines that rely on closed-loop regulation rather than open-loop motor control.

The motor uses a centering flange of 110 mm, which provides a repeatable mounting datum for gearbox faces or adapter plates. Heat is removed by natural convection, so no external blower is required for basic cooling and airflow remains simple. Power conductors exit through a connector on side A, which helps keep cable routing predictable around the machine frame and nearby components. It is configured as a motor for analog drives, so current regulation is handled by a compatible external drive. Position and speed signals are supplied through an incremental or absolute encoder with tacho feedback, allowing the control system to monitor motion continuously and respond to load changes.

The motor has no blocking brake, so holding force at standstill must come from drive torque or external mechanics. Feedback installation uses an incremental encoder with standard mounting, which allows the sensor arrangement to fit without special adaptation. The tacho element is supplied with standard quality, providing stable speed feedback for indexing tables, rollers, and similar motion tasks. Axes that must remain fixed after power is removed require a separate holding method because a brake is not built into the motor. The standard mounting approach also supports straightforward alignment of the feedback components at assembly.
