Nederlandse lrk motoren

Ik dacht al, nl is te duur om zelf voor de kleine model markt producten te maken.

Maar na beetje zoeken zie je op de site vh bedrijf zelf
(http://www.het-holland.nl/)
dat ze veel in China doen.

Verder nog weinig bekend, ook geen prijzen.
40 gr voor de kleine motor toch nog aardig gewichtig voor indoor/slowfly.

Dit heeft betrekking op de rood geanodiseerde motoren hierboven.

The data I show now was produced by Ulf Herder from a famous german company. (Schulze, rvs)

Here his reply to me.

Christian (Lucas? rvs) is today evening at my home and we have mesured the prototyp ofthe new small M273/6/19D.
Christian had not the correct size of the magnets: 5x5x1.5 SH38 instead of 5x6x1.5 SH38
We were surprised about the good results.
The results are in the attached file., before open it take a good beer and enjoy these good results.

With the correct magnet size the current will reduced by about 25% and the rpm droppes about 9%.

Note we didn't have the right magnets because they were not
ready. In 4 weeks all test will be ready and than we will know the
correct # of windings and thickness. he motor now is performing
above expectation.
