Trapezoid Bolt
|
The launch loop rotor is composed of separable bolts, mostly made of thin laminations of transformer steel, along with carbon fiber stiffeners, embedded aluminum induction motor conductors, and a central spine. The bolts are normally used in two modes; assembled into a multilobed rotor for the main tracks and inclines, and separated into separate bolts for minimum radius deflection. |
The density of 4% silicon transformer steel is 7.65 g/cm³, so A₁, the cross section of the area M₁, is A₁ = 0.65 cm² = 6.5e-5 m².~~~ A₁ = (A-C)×B .
Deflection Mode
In deflection mode, an electromagnet pole (shown at the bottom of this diagram) pulls the rotor towards it, with near-saturation flux density B_{max} , perhaps 1.8 Tesla. The material will be strongly saturated and with considerable hysteresis at this field strength; that actually helps regulate the deflection force.
