Answer / naveen

Yes one could determine the size of the conductor by knowing
the voltage levels and some other factors too.Also the
maximum voltage that can safely be applied to any winding is
determined by the type and thickness of the insulation used.
When a better (and thicker) insulation is used between the
windings, a higher maximum voltage can be applied to the
windings.
To be more specific by equations,
VD= 2*K*I*L/ CSA

WHERE:

VD= VOLTAGE DROP
I= CURRENT
L= DISTANCE OF THE LOAD FROM THE OUTLET (IN FT)
K= 12 FOR COPPER AND 19 ALUMINUM (FOR MAXIMUM TEMP OF 75 DC)
CSA= CONDUCTOR CROSS SECTIONAL AREA IN CIRCULAR MILS.

Answer / duminy

you cannot detrermine the size of the conductor by only
knowing the voltage level. awire of just 1mm thickness can
carry 1kv level of voltage. until and unless u complete the
circuit the current wont flow and thus no issues.the
current is the 1 who heats up the conductor n burns
it...dats why we always luk for current carrying cabability
of any conductor not voltage level.

I have a table fan of Rallifan Make. When I overhauled it I found a stator winding and an aluminum die cast rotor. So it is supposed that it is a 1 phase induction motor. But there are only two terminals coming out and there is no capacitor. Can any one tell how this motor works? or which type of this motor is?
