Product Description:

The MAC025C-0-QS-3-E/040-B-0 is an AC servo motor used in legacy motion systems that still rely on analog control architecture. As a motor for analog drives, it converts current-command signals into precise rotary motion for positioning, indexing, and speed regulation on automated equipment. The synchronous motor design supports stable closed-loop operation on packaging machines, printing equipment, and material-handling axes where repeatable motion and responsive speed correction are important. Because it is intended for older current-loop amplifiers, it fits retrofit applications where the existing control structure remains in service. That behavior is especially useful on indexing tables and feed axes that reverse direction often during normal production cycles.

Heat generated during operation is removed by natural convection, so the housing does not require a separate fan or liquid-cooling circuit. Installation still needs clear space around the housing so rising air can carry heat away from the frame. Power conductors enter through a connector on side B, which can simplify cable routing when the shaft faces the operator and the motor sits close to adjacent machine members. The frame uses motor size C and length code 025, indicating the diameter class and active stack length used for this version. This layout helps the motor fit compact axis assemblies without adding external cooling hardware. The absence of hoses and fans also reduces the number of support components around the motor body.

The motor runs without a blocking brake, so any holding force during power-off conditions must come from external mechanics or drive-applied torque. For axes that must stay fixed at standstill, an external brake or locking mechanism is typically required. Feedback is supplied by tachofeedback, and the shaft arrangement includes a second shaft end that can be used for an auxiliary device or additional sensing hardware. This arrangement is useful when the application needs analog speed feedback while still leaving a mechanical output point at the rear of the motor. As part of the MAC AC Servo Motors series, the unit follows the established connector and mounting layout used across that product line.
