SMC Somaloy – More Efficent Motors
A few days ago HobbyKing indicated they are experimenting with a Soft Magnetic Composite (SMC) alloy as a brushless motor stator material.
The following is a twitter feed from the HobbyKing blog.

SMC Somaloy material for stator builds. No other R/C motor producer has ever used such an advanced and efficient material for producing stators. We’re currently prototyping the new material for solid stator production which greatly increases motor efficiency. The stators are extruded from molten Somaloy material to create a material with iron losses far lower than a standard Stator motor and with less wire for the same Kv and voltage. Our initial tests have shown amp draw to be far lower than is needed with a standard stator motor. We wont have the exact numbers until March when we dyno test motors side by side, but from looking at propeller size differences we are calculating around a 20% increase on an already very efficient motor. THIS COULD POSSIBLY BE THE MOST EFFICIENT R/C MOTOR EVER BUILT.”

Here’s a link to an article from Hoganas, the producer of Somaloy materials which offers some insight into using these materials as motor components.
The results of HobbyKing’s comparison should be interesting and potentially marks a significant step in brushless motor development.
