Magnetic Orientation Technology – Radial AND Multipolar and Applications
Proper application of magnetic materials requires attention to several factors
including benchmarking, material considerations, assembly techniques and design
optimization. Using radial NdFeB ring magnets in permanent magnet motors
provides a cost effective and simplified assembly method to improve motor
performance while increasing production yields. This presentation will focus on
design considerations and assembly methods using patented radial ring magnets
that improve balance, while reducing noise, vibration and cogging torque.
The patented production method uses rotating orientation technology. Specifically,
rotating orientation technology presents a unique methodology for creating novel
and application centric materials that provide improved performance in rotating
devices such as DC brushless motors. This presentation will review design
considerations, along with assembly, magnetization and magnetic wave form
testing that allows correlation with motor testing.
