Re: (ET) motor on E12S...

[Dave & Debbie Barden <daveb seanet com>]

not being too electronically literate I need some help getting from A to 
C, A 
being my motor has a shunt which supplies the field.  To get to C I have 
to be 
sure that the sep-X controller will work with that kind of field.  One of 
Richardson's emails talked about their needing to modify the controller to 
work 
with small current of the E15's field windings 3 amps instead of 30 I 
think he 
said.  Judging from the small wires going to the field of the E12S motor 
and 
the fact that it uses a shunt I would guess that the current would be 
pretty 
low as well???  And if steve is correct that the E12S uses an E15 like 
motor it 
should work.  What I am really worried about is what will happen if my 
field 
loses current (blown fuse or fried relay) will the armature still be 
getting 
current from the controller???

thanks,
dave
