Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI673LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It pairs with analog servo drives to generate controlled torque and speed for positioning axes in automated machinery. The motor converts drive current into shaft rotation, while its integrated feedback devices return motion data to the control loop. This closed-loop arrangement allows the connected drive to correct changes in position and speed as the mechanical load varies during operation.

The motor dissipates heat through natural convection, so it does not require an auxiliary fan or liquid-cooling circuit. Heat passes from the enclosure surfaces to the surrounding air, allowing the motor to operate without separate cooling equipment. The motor has no blocking brake, so an external clamp or drive-generated torque must secure a static load when required. Its motor size 025 establishes the primary frame dimensions, while motor length C indicates the axial housing and lamination-stack length. Power conductors exit through a connector on side B, providing a lateral cable-routing path that can keep the power wiring clear of the feedback leads and nearby machine components.

The feedback arrangement provides tacho feedback with incremental or absolute encoder support, allowing the drive to receive speed and position information for closed-loop motion control. Tacho feedback supplies a velocity signal that the analog controller can use to regulate shaft speed under changing loads. The installed secondary channel uses an incremental encoder with standard mounting, which supplies pulse-based position data during rotation. Incremental feedback supports accurate movement tracking after the control system establishes a reference position. Classified as a motor for analog drives, the unit is intended for amplifiers that regulate motor current through analog command and feedback signals. This control arrangement supports positioning and speed-regulated applications in transfer lines, material-handling equipment, and pick-and-place machinery.
