Slotless brushless servo motors achieve ultra-performance

The FP slotless design provides higher power density, superior peak torque, higher speed, improved efficiency, with zero cogging. This is our most power-dense synchronous servo motor family. The motor series comes in 7 frame sizes ranging from 38 mm to 140 mm with multiple stack length options available. These motors are considered medium inertia making them perfect for larger load applications. This series can come with customized windings on top of the three standard choices (48, 320, and 600 Vdc). Feedback options are nonproprietary allowing these motors to be used with most third-party servo drives. Looking to improve your machine performance or just reduce size and weight, this is the motor for you!

Brushless servo mating cables can be found HERE. These are used when straight or right-angled connectors are chosen as motor options.
