long bars (1.00 / 1) (#1)

As noted by others (Rodger maybe...) the long bar magnet idea will probably work fine if the entire top face of the magnet is a single pole (N or S) and probably won't work at all if one end of the bar is N and the other end S.

Clamping/gluing magnets cheek to cheek like that can be something of a trick. You may need to glue them one at a time until the glue completely sets up for each one.

Best regards and have fun!

OK well lets try it again? HI Richard. I've had a thought about this curved magnet problem. There are curved ceramic magnets galor in pm motors. Many have 2 but you need 4. And ceramics are weak. This might be a little better than ceramics? Take a thick wall steel tube the same diamter as your motors armature. Since your motor is 4 pole. Cut this tube into 4 pices like a pie. cut it so there is a gap between the pices. Glue the magnets to the under side of the tubing pices then glue the magnets to the greatly redused in size armature. This would get the flux closer to the laminations and cover the pole more thouroughly. There will be a reduction in flux travel. But the 2 surfaces will be better mated together and hopefully overcome some of the square surface losses. JK TAS Jerry
