SyMAX®-i Motor

The SyMAX-i permanent magnet ac motor (pmac) joins the Marathon® SyMAX® line showcasing intelliDrive technology, an integrated control to help with constant torque. In a single housing, this allows higher power density in a smaller size/lighter weight frame package.

The Marathon® brand has a developed reputation for conservative motor designs and highly engineered products used in a vast array of commercial and industrial applications around the world. Today, we build on our legacy of innovative and efficient motor designs by the joining of magnetics and motors into a single leading technology. This allows for unparalleled power densities, unprecedented performance, and unmatched efficiencies.










The SyMAX®-i motor is designed to operate continuously in a 60°C ambient and provides for quiet operation. The built-in passive power factor correction (85-89%@FL) circuitry reduces voltage drop thus saving money.
