Materials and
construction
The stator is made from 29 gauge, M15 electrical steel
laminations, which are stacked and bonded. Trapezoidal bars of
aluminum are inserted into the
stator
core, exceeding 90% slot fill (compared to less than 50% for
motors with traditional copper windings).
The rotor is made from precision machined steel bar and has
twelve high-temperature (180°C) neodymium-iron-boron (NdFeB)
magnets mounted on its circumference. The magnets are retained
with stainless steel bands and the rotor is balanced prior to
assembly.
Following our commitment to high quality, high performance
materials and components, Nachi bearings are used throughout our
product line. 30mm
double-row angular contact bearings are standard.
The rear cover is comprised
of glass-filled, high temperature thermoplastic, which is
precision machined. A magnetically coupled coolant pump may
be added, when necessary.

Electronic Commutator
Integrated electronics are mounted on the rear cover and
cooled with a brushless fan. This enables the SolidSlot brushless motor to be run directly from a battery
or with an industry standard DC motor controller.
For
increased flexibility, the electronic commutator can be mounted remotely and
cooled by air or liquid. (shown).

Utility
A
broad range of configurations are possible, some as simple as
adding the desired shaft adapter. In general, the SolidSlot™
can support a broad range applications, including mobile
hydraulics, marine propulsion and generation, robotics,
integrated starter/alternators, diesel, gasoline and gaseous fuel gen-sets, and large centrifugal pumps.
Power Generation
As a result of the
electronic commutator, the
SolidSlot™ brushless motor/generator may be
used to directly produce DC power through high efficiency
synchronous rectification. The voltage is proportional to speed
and the resultant DC power may be used for battery boosting or to
power an AC inverter. More information can be found on the
APU page.
