Question

1. what is the purpose of the bearing in a motor? 5. what is the purpose of the rotor in a motor? 6. what is the purpose of the electrical connector in a motor? 7. what are the two main types of motor, when classified based on the type of electric current used to power the motor?

Explanation:

1. Bearings in a motor support the rotating shaft, reduce friction, and enable smooth rotation.
2. The rotor in a motor is the rotating part that interacts with the magnetic field to produce mechanical motion.
3. The electrical connector in a motor is used to connect the motor to the power - supply circuit, allowing the flow of electrical current.
4. The two main types of motors based on the type of electric current used are AC (alternating - current) motors and DC (direct - current) motors.

Answer:

1. To support the rotating shaft, reduce friction, and enable smooth rotation.
2. To interact with the magnetic field to produce mechanical motion.
3. To connect the motor to the power - supply circuit for current flow.
4. AC motors and DC motors.
