Having watched this video, I now understand the woking of a shaded pole motor. Good job. Thanks. Btw, the inventor of it was a genius- it’s so simple and so elegant.
Excellent explanation, if not the best so far on youtube. If you are buying an appliance with this kind of motor in it, understand you are buying a cheap piece of crap if it's purpose is anything other than spinning a space heater fan. These are 15% efficient typically. In a heater... this can pass as the motor's excessive waste heat simply contributes to the purpose of the device. But on anything else not intended to heat... garbage. Go with a higher end fan or appliance that uses the PSC motor (permanent split capacitor). Much quieter and significantly more efficient.
Good description, however, I usually see the flux lines pointing in the opposite direction (like in a magnet - lines exit the N pole loop outside the field, come into the S pole, & move from S to N within the magnet).
Please explain how a current is induced into the rotor. Why are the laminations stacked in such a way that the laminations form trapezoidal poles in the rotor.
+shawn hill If you remove the shading poles it's no longer a shaded pole motor, but instead becomes a 3 phase ac motor. You'll just need to supply 3 phase supply to the motor.
wow this means the shaded pole motor is also an ac induction motor but made super simple without the need to use any form of running or start capacitor?
Roddy Mc Namee thanks for the info roddy, what about you tube videos seen running two of such motors self looping and running a load on top of it..you think its possible? the video shows a small capacitor in parallel to one of the self looping shaded motors..
+Bobby Sri by flux he means magnetic flux = lines of force from the magnet ... flux is a greek word meaning 'flow' you can see the direction of magnetic lines of force indicated by the arrowheads on the lines :)
