Product Description:

The MAC025C-0-QS-2-E/040-B-0/S001 is a servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. As an electromechanical actuator, it converts drive controller current into proportional rotary motion so machine tools, conveyors, and automated handling stages can position loads with repeatable accuracy. The motor belongs to a family designed for compact industrial axes where precise speed regulation and stable torque delivery are required under continuously varying process conditions. In this role, it supports repeatable starts, stops, and speed changes during indexing, feeding, and transfer tasks. It is typically installed inside enclosed machine frames and coupled directly to ball screws, timing belts, or planetary gearheads to minimize transmission play.

Thermal management relies on natural convection, meaning heat leaves the stator surface without forced airflow. This allows the motor to operate in quiet or sealed enclosures as long as ambient temperature remains within the permitted range. Because no fan is required, the design can help reduce airborne dust movement inside tightly enclosed equipment. Speed feedback is returned to the drive through an integrated unit with tacho feedback, which provides an analog voltage proportional to shaft velocity for simple speed loops. The motor has no blocking brake, so vertical axes require an external holding method when the load must remain fixed at standstill.

The motor size of 025 and frame length C provide a balance between continuous torque output and inertia in a compact housing. Power conductors exit through a keyed connector on side B, positioning the cable away from gearbox flanges when the motor is installed with its shaft toward the workpiece. This layout can simplify cable routing in compact assemblies where clearance around the shaft end is limited. As a motor for analog drives, the unit is intended for systems that use conventional ±10 V command signals while retaining MAC-series mechanical compatibility.
