My life's work has been in magnetics (got attracted to the magnetic field in 1960) so I'll offer a few comments. Supermalloy is a refined and specially...
Goedendag, A weight saving example: <http://www.rcgroups.com/forums/showpost.php?p=3383224&postcount=39> Would mind him making 4 wheels for my Toyota ;-) Met...
That was impressive. I have such of cnowledge about as you do. Thank you very much. But one thing it is sure: These red cores (please look my Album) I have...
Sorry - it need to be: I have NO such of knowledges about this area like you have. (or something like this... Im not sure...my English is really poor) Regards,...
... Funny about that - I caught the same disease and also enjoy the opportunity to do some unusual magnetic design work at the Physics Research Lab where I...
mh-mhh, ... it ... suitable ... I dont know - because I try, Of course I like to get some different types of magnetic tapes but from where? It was so hard to...
Colin, Im experimenter, My "Hard Disk" does not acquire not by a long sight all, But I see that with high current it is not possible to cut correct slots in to...
... Apart from cost, a disadvantage of very thin laminations is the "packing factor", simply meaning that a greater proportion of the volume is occupied by the...
Herbert & Colin, Your work and energy is impressive, I also discover things intuitively, by trial and error. In the days before computer (BC, B4PC~1980) I...
Hi Everyone, It has been a long time since I have written. I have been watching and doing and even a little buying. This is where my problem comes in. A...
hi, I can only delight in. #What is the best magnetic material for bldc motor stators you can recommend (*material*thickness*where to get*) ? #What do you...
Greetings Herbert, I worked in Europe & lived in Brussels from 1977-1980. Your questions are not easy to answer. First, because ESC frequency is very high,...
... I agree with what you say about cores in high frequency applications, but wonder if you have missed the point for BLDC motor applications. The large, AC...
Being new to this hobby, I did miss the pont about the lower effective frequency. Please point me to a post or URL that discusses ESC operation. High amp...
Colin, Hm, why to speak about my some tests of motor ;-) It does not matter how many poles - 2 pole or 10 pole. When 2 pole motor makes 120.000 rpm and 10 pole...
Regarding to core materials mr Herbert check this site this is what they clame: Sumitomo Electric Industries, Ltd. (SEI) developed a revolutionary sintered...
... Actually, a 2-pole motor at 120,000RPM represents a frequency of 1000Hz, not 2000Hz. You are forgetting that one complete electrical or magnetic cycle...
Colin, Im forgetting nothing, Im just thinking: May be you have some kind another system in Australia ;-) In Europe 1 minute = 60 sec. If 2 pole motor spins...
hi, Where to get this powder? I do be afraid that SEI will just ignore my message where Im asking to send one kg of their "powder" ;-) Thanks anyway, Herbert,...
Greetings to members, Myself and a friend of mine want to build some BL motors for a RC boat, not necessary for racing just something to cruise around the lake...
This is a totally scratch built rotor bell. It is 8 inches in diameter. Originally, I intended to use 16 magnetic poles and 12 point stator star wound. That...
@Datlt There are usually 12 magnet poles in the ring magnet of a CD-ROM motor. Cheers Christo @Jeff I fail to see what your post has got to do with this thread...
