Authoritative PPT Summary
"Magic Little Motor" Energy PPT Courseware
There is a small motor in the electric toy car, which drives the car forward.
1. What’s inside a small electric motor?
Composition of electric motor:
1. Shell (with magnet)
2. Rotor commutator coil iron core
3. Back cover (with brush)
Along what lines does current flow through the coil?
The route of current flow: battery → back cover wiring → brush → commutator → coil → commutator → brush → back cover wiring → battery
2. The secret of small motor rotation
Let the rotor rotate while you can see it
The key to production is to make a "V" shaped "brush".
Let the small motor rotate and connect the components of the small motor.
Change the rotation state (direction, speed) of the small motor
judge
1. There are many coils wound around the rotor core in the small motor. ( )
2. The rotor of a small motor is equivalent to an electromagnet that becomes magnetic after being energized ( )
3. There are only two sets of coils on the rotor of the small motor. ( )
4. During the rotation of the small motor, the brushes contact the three metal rings of the commutator in sequence, and the direction of the current passing through the rotor coil will automatically change. ( )
5. The function of the brushes and commutator in the small motor is to connect the electromagnet in the rotor and change the direction of the current. ( )
6. The speed of the rotor of the small motor can be changed. ( )
1. What can speed up the rotation of the rotor of a small motor is ( ).
A. Use two magnets B. Reduce the number of turns of the coil
C. Reduce the number of batteries
2. The rotation direction of the small motor has nothing to do with ( ).
A. Change the direction of the current B. Change the magnetic poles of the rotor magnet
C. Increase the number of turns of the coil winding
3. When the small motor is working, turn ( ).
A. Chemical energy is converted into mechanical energy B. Mechanical energy is converted into electrical energy C. Electrical energy is converted into mechanical energy
4. The basic principle of a small motor is that electricity generates magnetism and uses ( ) interaction to rotate.
A. Mechanical energy B. Thermal energy C. Magnetic pole
5. A broken magnet ( ).
A. There are North and South Pole B. There is only South Pole C. There is only North Pole
