Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI652LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for use with analog servo amplifiers, it converts commanded current into controlled torque for positioning and speed regulation in automated machinery such as light conveyors and pick-and-place modules. Integrated rotary feedback lets the associated drive close velocity and position loops, giving the machine precise motion control across repetitive cycles. This operating style suits compact automation axes that require repeatable starts, stops, and short travel moves.

For heat dissipation, the motor relies on natural convection, so it must be mounted where ambient airflow can remove waste heat during continuous duty. The motor has a motor length 025 and a motor size B frame, which set the axial stack height, flange dimensions, and shaft diameter for gearbox or coupling interfaces. Position feedback is provided by an integrated incremental encoder that creates uniformly spaced pulses for the speed loop. Because the unit is supplied with no blocking brake, holding torque during power-off must be delivered by an external locking device or by keeping the drive energized.

The side-mounted power terminal arrangement uses a connector on side B, simplifying cable routing inside compact enclosures because the supply leads exit away from the driven load. Speed verification is handled by built-in tacho feedback, which delivers an analog signal to the controller for stable regulation at low speeds. Electrical connections follow the conventions of analog drives, allowing the windings and tachometer leads to reach the amplifier without digital conversion hardware. The separate feedback channels help the amplifier manage both speed correction and position-related control tasks during repeated machine cycles.
