We offer two thicknesses of aluminum and two thicknesses of steel sleeves the aluminum sleeves are for decreased inductance and the steel are for maximum BL. The first part of the sleeve system is the “pole sleeve” – we currently offer 4 versions of this sleeve and this one is permanent and epoxied into place with a high temperature 3M epoxy.Every NS v.3 starts out with a HUGE gap before being “sleeved out” as we call it. The sleeve system: This is something ALL new that nobody has done before.

We leveraged the advantage of the huge motor of the NS v.3 (quad stack 250mm magnets) so we could take advantage of a 4-layer coil – the 4-layer coil keeps the mass and inductance down while allowing us to use such a long coil – and the huge motor allows us to still achieve the level of BL we desired.
