thanks!!! hahaha i love finding ways to recycle junk into new projects.
but if i get this to work than for the record it was actually my neighbors idea
,we both watched the dvd, drooling at the possibllities LOL, I ,not knowing as much about motor geomitry as he, was all set to research what it would cost to custom make a new laminated C shaped core and coil when mark, my neighbor, piped up and said "that looks like a shaded pole motor!" hahaha and I with a deer caught in headlights look in my eye replied "whats a shaded pole motor?", hehe, he in turn described it and of course i just had some "lying around" in my shop from appliances i tore apart. so that said...
i didnt know about the glass in laminations and i do have a portaban saw i was tempted to use to save money but i was allready going to see if the local high school might cut it for me with there plasma cutter. do you know if there would be any problems, would i damage the motor, if i use this type of cutter. if so and since i am willing to pay a machine shop or high school to "cut it right" the first time, what type of tool would you recomend?
second i am still curious about how to cut the core. i left two possible highlighted pictures on my seb site to choose from. one of the pictures shows a cut that leaves the largest continous stator contact surface area possible. and the other picture shows a cut with a much smaller stator contact surface area. if I use the simple bar rotor idea i would be tempted to assume that first the width of the rotor bar must match the the stator "brush" width and a wider rotor/stator would give more motor torque/power because there would be more surface area on the end of the rotor to "pull" into the stator. electricly this would also mean the electric pulse duration is longer so i would use more power but... the collected cemf would be more as well so maybe the "payed for" input would be similar.... so unless you believe there is an important reason not to have the large stator surface area i will have it cut for the large one.
also i am curious as to why the S rotor wont be better and the bar idea and, since its in your dvd, when would this design be appropriate?
thanks again!!
