2. INTRODUCTION
• Presently we are using ac & dc motors,
generators and other special motors.
• This all motors use conventional sources of
energy.
• We are introducing a motor which uses a
nonconventional source.
• So here we are introducing “Solar Motor”.
3. Idea In The Project
• In this motor we are mounting solar cells on
rotor which is having armature winding.
• Permanent magnets used instead of field
winding.
• Solar cell supplies the current to armature
winding.
• Using this concept the solar motor works like
a dc motor.
4. WORKING
• When light strikes one of the solar cells, it generates an
electric current thus energizing one of the rotor
windings.
• This produces a magnetic field which interacts with the
field of the stator magnets generating a force
perpendicular to the length of the coil.
• This interaction causes the rotor to turn. As the rotor
rotates, the first solar cell enters shadow and the next
solar cell moves into the light and energizes the second
winding.

7. ADVANTAGES
• Motor is independent of electric supply.
• It is environmental friendly.
• Weight of motor is very less.
• Pollution free, less noisy.
• Minimum maintenance is required.
• Can be used in remote areas.
• Operating cost is negligible.
• No starting methods required.
9. Some specification of Motor
• Speed - 850 RPM.
• Each Solar panel - 9V DC, 0.11Amp., 1Watt.
• For 6 solar panel – 6 Watt.
10. COST ESTIMATION
• 4 to 6 solar cells - 2000 to 3000Rs
• a coil of 0.2 mm enameled copper wire - 300
to 350Rs
• Fiber case & shaft tube or any wooden rod -
1000Rs
• Permanent magnets - 800 to 1000Rs
• Total estimated cost - 5000 to 7000Rs
