Product Description:

The MAC025C-0-QS-4-E/040-A-1/WI678LV is an AC servo motor in the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. This model fits the compact 025C mechanical frame and serves closed-loop motion axes that are commanded by analog reference signals. In automated assembly cells, packaging stations, or light material-handling modules, the motor converts electrical input from analog drives into tightly regulated rotary motion so that loads can be positioned with repeatable accuracy. Its compact format suits installations where axis space is limited but consistent speed and position control are still required.

The motor relies on natural convection for heat dissipation, and its ribbed housing passes thermal energy to ambient air without auxiliary fans. This cooling method reduces cabinet complexity and avoids the added wiring or maintenance associated with forced-air accessories. Position feedback is provided by an incremental encoder with standard mounting, which delivers a consistent pulse train that the drive uses for velocity and position loops. The mechanical envelope is set by the length code 025 and frame code C, which indicate the stack depth and flange geometry used for this motor.

Power conductors exit through a connector on side A, letting the cable follow the machine frame while staying separated from low-level signal wiring at the opposite end. An integrated standard blocking brake secures the shaft whenever torque is disabled, helping prevent load drift on vertical or suspended axes. Electrically, the unit is classified as a motor for analog drives, so its interface aligns with amplifiers that accept ±10 V or ±12 mA commands instead of digital fieldbus traffic. This arrangement makes the motor suitable for systems that use conventional analog control rather than network-based motion commands.
