| Summary: | This thesis is about the feasibility studies of converting a mechanism consisting of
two concentric rotors into a dual-output pulsating stator-less motor. The rotors are
meshed into each other, wherein the blade ofthe first rotor comprises ofelectromagnets
while the blade of the second rotor comprises of permanent magnets. Each rotor is
connected to its own shaft installed with an overrunning clutch which allows both rotors
to rotate only in a single direction. The motor was designed, fabricated and tested. The
types ofcircuits to be used was analyzed and it was concluded to be a series connection
circuit. AC current was supplied to the electromagnets through slip rings. The effect of
changing electric current frequencies on the performance of the motor was studied.
Several frequencies of current in the range of 1 Hz to 60 Hz were tested in the
experiment. When the switching of current frequency is low, the rotors tend to collide
with each other resulting in loss ofenergy. Whereas, the high switching frequency will
result in the retardation ofmotion, also leading to loss ofenergy. |
