The construction
of the linear accelerators is done along the tube length in different locations
for the capsule acceleration. The capsules have rotors for transferring
momentum through the use of linear accelerators.

The structure of
the linear accelerator rotor is simple. It includes a blade made of aluminum with
the length of 49 ft
(15 m), height
of 1.5 ft
(0.45 m),
and thickness of 2 in.
(50 mm).
The flow of the current mainly takes place in the in the outer part of the
blade (.4 in.
or 10 mm);
thus, it allows the hollow space to ensure reduction in the costs and weight.
There is a gap on each side between the stator and the rotor of 0.8 in. (20 mm). The capsule enters
the gap, stays within, and exits safely owing to an effective combination of electromagnetic
centering forces and the control system of the capsule.

Mounting of the stator
is done to the tube bottom over the length of 2.5 miles (4.0 km). It is done for the
deceleration and acceleration between 300 and 760 mph (480 and 1,220 km). The approximate
width including the air gap is 1.6
ft (0.5
m); the height is 4.0 in. (10 cm), and the weight is 530 lb/ft (800 kg/m).
The symmetrical layout on each side of the rotor has the 3-phase electrical
configuration with one slot per pole and per phase. The linear pitch is viable (maximum
1.3 ft
or 0.4 m).
There is no fixed quantity of turns per slot along the stator length; that
enables the operation of the inverter at the phase voltage which is almost constant.
It makes design of the power electronics much simpler. The resistance of the 20
lbf/ft (300N/m) magnetic forces by two halves of the stator has the requirement
of bracing for bringing both parts together.



Table 1 shows the
total cost of the Hyperloop passenger capsule. According to the estimations, it
will be approximately $1.35 million USD. This amount includes the costs related
to the assembly and manufacturing. There will be forty capsules required, and the
overall cost of Hyperloop system capsules must not exceed $54 million USD which
is equal to 1 per cent of the total budget. Table 2 shows the estimated cost of
a large capsule, although increase in size will definitely increase the overall
project cost. Such larger capsule will carry cars, cargos, and passengers. There
will be an increase in the capsule frontal area to 43 ft2 (4 m 2). Corresponding increase
in the diameter of the tube will be up to 10 ft 10 in. (3.3 m).
