Using a reed switch.

BASIC BRUSH LESS MOTOR USING A HALL SENSOR

Still another switch, a Hall Sensor.

BASIC BRUSH LESS MOTOR USING A MICRO SWITCH

        This is a basic brush less motor. Note the micro switch on the round peg. The spinner touches this switch which turns on the coil above attracting the magnet. Past the switch the coil is turned off allowing the magnet to continue on.

NEXT LEVEL MOTOR 2 POLE WITH COMMUTATOR

                         This motor has 2 poles. Power is fed to it via commutators and brushes. The commutator reverses the current flow into the coils so that the poles gets attracted then suddenly repelled by the stationary magnets.

SIMPLEST DC MOTOR




   

PARTS

Copper wire
Wooden base
One or two magnets
Battery case with 4 AA cells


     This motor is based on the  coil being turned on and off by an insulation on the shaft itself. On one side of the shaft touching the holder, all the varnish is removed. On the other end, only half side is removed. So the electric flow gets interrupted to the coil.

TOY ELECTRIC MOTORS

     I build my first e-motor when I was 10 years sold. Had a book "Boy Mechanic". Today, there is a big leap in advancement towards BRUSH LESS MOTORS where the magnets are rotating as opposed to old motors where the magnet is stationary.

    For the motor to be investigatory, it must be OPEN, meaning it can be seen inside out. I will display here some of these old style and new style motors.


Thank You.

* Senior Citizen
*ADMU graduate 1973, economics
*Investment banker by profession with forte in financial analysis
*Strong passion for technical matters, electrical and electronic devices.
*Builds model boats and airplanes.
*robotics

     But my aim is to produce INVESTIGATORY SCIENCE PROJECTS mostly electric and electronic devices, model boats, model planes.

     I dedicate this blog to my late mother whose birthday is today.
