New Bruss-less Motor And Esc

[fvbreemen]

High-end Technology Holland is proud to announce that it has started with the production of sensor-less brush-less motors and Sensor-less brush-less electronic speed controller. Motors and controllers will come available end of October beginning of November.
The motors use high-grade neodym magnets ( no ring magnet like CD-ROM motor they perform only a little better than ferrite magnets. These types of magnets suffer form magnetic imbalance. ). Our first motors will be the out-runner types and are a good substitute for the B20S size motors with reduction gear. Our next motor will be a good substitute for the B20L with reduction gear. Our motors can swing large propellers without gear-drive.
Motors will be shown at the Chicago show in September. We plan to have the combo ready for the Las Vegas show in October.

Now our speed controller, it is a sensor-less brush-less programmable controller the will work with all commercially available brush-less sensor-less motors from 2-14 pole. The software automatically senses the correct firing angle and adjusts to the correct angle. Our small controller shown in the pictures weighs without wires 4 grams and can handle 6-10 cells or Lipo’s and continues Amp draw of 10 amps with sufficient cooling. The ESC has 6 modes from which one is a Helicopter mode( fix RPM). It has soft/hard brake soft –start cut-off overload protection. All these features can be programmed. Software updates are easy.
We will produce different size controllers.
Pricing is not available now but we can assure you that a combo will be in everybody’s league.

Forgot to mension the dimensions for the motor

diameter 29 mm
shaft diameter 1/8 inch or 3.175 mm
weight for the short version ( 23 mm) appr 40 grams
long version ( 32 mm) app. 70 grams

motor controller combo ( short indoor) < 50 grams
Motor controller combo ( long outdoor 20 amp version) <90 grams.

nice. can you provide motocalc numbers so that we can run the calculations? or any benchtest data available? also, max amps/volts for these motors, continuous and pulse?

[Jim McPherson]

Will they be available in the U.S.?

Whooohoooi!!!

I want some!! :D:D

locally available brushless motors/controllers... DROOL!!! :cool:

Hans

Need a beta-tester? ;)

[Happy|Harry]

Very nice looking :D
About time some more "realistic" priced b/l motors & esc's came on the market

I can't wait :D

sorry for now ;)

It's sizzling hot here in my office, I'm off for the weekend.

Ehm...well...

The data I show now was produced by Ulf Herder
from a famous german company.

Here his reply to me.

Christian 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.

I forgot to mention that the mounting of the motor can be reversed, the shaft can be pulled out after loosening 2 set screws
in the rear plate. So that you can mount the motor to a firewall
or bulkhead.

[i].....Too bad you'll never see it legally in the US, as US law forbids the import of any product of Chinese Prison camps.... I guess thats ethics for you.....
Steve [/B]

Erm Steve, what makes you think that these motors are made in Chinese prison camps ? (am I missing something ?)

Franck

[Happy|Harry]

so how about some pics and pricing details of the finished motors and esc's

phil

[Franck]

just saw that rbc kits in holland has them in stock. Nice motors! (from 50 euro and up, not bad)

[DNA]

Some specs are available at http://www.edogfight.com/Catalog_page/MotorBrushless.htm

[Shawn Palmer]

The manufacturer has neither confirmed nor denied the prison camp story

Possibly because the question itself was rediculous?

Shawn

[Shawn Palmer]

Best to be absolutely sure i'd say...

Or at least obtain accurate and verifiable information before posting reckless and actionable accusations?
