GRISMIR® G2.0kW Alternator/Generator
Thor Power will begin shipping alternative energy generators & alternators in June 2012, and we are
seeking your custom.
Our first high speed alternator/generator product is Grismir®. It is an alternating current slot-less stator,
and a permanent magnet rotor. It is capable to operate in a high variable speed range from 700rpm up
to 30,000rpm due to its specific structure. Table I shows the machine specifications in detail. The
performance of the machine under different load condition is shown in Fig. 1. Fig.2 shows the design
and dimensions of the Grismir® motor/generator. This figure demonstrates that the machine is probably
the best weight to output of its class.

Fig.1 Grismir® Alternator/Generator Power Output performance under different load conditions
Please note: these units are not certified or approved by UL or any other qualifying agency.
As it has 2 poles for 60Hz output, the shaft should be turned with 120*60/2=3600rpm, and for 300Hz the shaft should be turned with
120*300/2=18000rpm.

Testimonial, May 2012: UOIT [University of Ontario Institute of Technology] Team & GRISMIR® Hydro-
generator G2.0kW...The Team Report, in part, “…we were very impressed by [G2.0kW]
performance…water temperature in early April was cold…did not seem to affect generator
performance…under load and with no load, output voltage was the same for both units…major
advantage of your design… compact; space inside our prototype was limited and your generators fit
perfectly…they weighed much less when compared to others we had researched…worth the $3000
asking price...we received an honourable mention." Did 9 volts/unit @1800rpm & claimed could have
easily run at 5x that speed – no fan! [Max. operating temperature w/o fan @ 110°C; fan available on
request; video of this application to be posted on YouTube, June 2012].
Price & Delivery: $US3000 each, FOB, Allentown PA USA; expected shipment, end March 2013.
