Product Description:

The MAC025C-0-JS-2KE/040-B-0/S008 is an AC servo motor in the MAC AC Servo Motors series. It is configured as a motor for analog drives, so it operates with servo amplifiers that issue a ±10 V speed or torque reference instead of a digital command stream. In material-handling stations, indexing tables, and light machine-tool axes, the motor converts those commands into controlled shaft motion while keeping the installation compact enough for close-coupled assemblies and limited mounting space. This arrangement makes it suitable for machines that continue to use established analog control platforms and require consistent rotary response from a compact motor.

This model uses natural convection for cooling, so the housing surface must remain exposed to ambient air for heat to leave the motor efficiently. The frame is identified as size C, and the active stack corresponds to motor length 025, a combination that gives the unit a compact profile with moderate continuous output for lighter servo duties. Its electrical characteristics follow winding code JS, which allows compatible amplifiers to match the motor’s phase values for stable current regulation. The molded power connector is located on side B, helping keep the cable path away from couplings, pulleys, or other drive-end hardware that may be mounted on the opposite side.

The motor is supplied without a blocking brake, so any suspended or back-driving load must be held by external hardware or by drive torque when power is removed. Integrated tacho feedback generates an analog signal proportional to speed, which lets the amplifier close the velocity loop with direct rotary information from the motor shaft. Because the feedback is produced at the motor, response stays closely tied to actual shaft speed during acceleration and deceleration. This feedback method is well suited to existing analog motion systems that use straightforward speed regulation rather than newer digital encoder formats.
