Product Description:

The MAC025B-0-ZS-4-E/040-A-0/WI673LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts precise torque and speed commands from compatible servo amplifiers into rotary motion for positioning axes such as tooling heads and small conveyors in automated lines. By translating low-level voltage references into controlled movement, the unit supports repeatable axis control in installations that do not employ digital fieldbuses. Its compact frame eases installation in confined enclosures and supports rapid acceleration cycles needed for high-throughput machinery.

The motor uses frame code 025 with size code B, a combination that gives low- to mid-range torque capacity in a compact package. Heat is removed through natural convection, so no external blower or liquid loop is required and enclosure airflow must accommodate the surface temperature rise. Input power is routed through a connector on side A, which simplifies harness layout when the motor is placed against a machine wall. Rotor position is delivered by an incremental encoder with standard mounting, giving the controller a sinusoidal feedback signal for velocity loops and homing functions.

To integrate with legacy drive racks, the motor is supplied as a motor for analog drives, and its sensor wiring supports tacho feedback, incremental encoder, or absolute encoder formats so the controller can use the required signal type. The motor is supplied without a blocking brake, which eliminates drag and requires external holding if standstill torque is needed. This brake-free arrangement also shortens the body and lowers inertia, which helps on compact axes that favor quick response over built-in holding capability. It is well suited for small conveyor, feed, and positioning applications where the machine or drive provides any required holding force.
