Question

1. motors convert ____________ energy into ____________ energy
2. one example of a non - electrical motor is a ______________ motor
3. the part of the motor that stays fixed in place and generates a magnetic field is called the ______________
4. 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. Motors work on the principle of electromagnetic induction. Electrical energy is converted to mechanical energy as the motor operates.
2. A steam - powered motor is an example of a non - electrical motor where steam pressure is used to create motion.
3. The stator is the stationary part of the motor that generates a magnetic field.
4. The bearing in a motor reduces friction between the moving parts, allowing the rotating shaft to turn smoothly.
5. The rotor is the rotating part of the motor that experiences a force due to the magnetic field created by the stator, resulting in mechanical rotation.
6. The electrical connector in a motor is used to supply electrical power to the motor, enabling it to function.
7. 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. Electrical; mechanical
2. Steam - powered
3. Stator
4. To reduce friction and allow the shaft to turn smoothly.
5. To rotate due to the magnetic field and produce mechanical motion.
6. To supply electrical power to the motor.
7. AC motors; DC motors
