Definition and introduction of electric motors
Electric motors are devices that convert electrical energy into mechanical energy. These motors are used in a wide range of applications, from small household appliances to industrial equipment. An electrical engineer works on the basis of Faraday's law of electromagnetic stimulation, according to which a general electrical current through a magnetic conductor results in a mechanical force.
Electrical components:
1. **Stator**: It is the fixed part of the motor that contains the electrical windings. Create a magnetic field.
2. **The rotor (rotor)**: It is the moving part inside the motor that is connected as a result of the interaction of the magnetic field of the stator with the electric current.
3. **Windings(s)**: Wires coated with the magnetic field attached to the wire when an electric current passes.
4. **Structure (Framework)**: The nutrients that contain the nutrients.
5. **Bracket(s)**: Supports the rotor and reduces synchronization during busy period.
6. **Carbon brushes (brushes)**: In a rotary motor, it radiates electricity to the windings on the rotor.
Motor data:
It has a small crank plate designed to contain powerful information about the engine, and helps in correctly identifying its new characteristics. It usually contains the following information:
1. **Electrical power (energy)**: Measured in watts (W) or kilowatts (kW) and determines the amount of energy that can be generated.
2. **Voltage**: Shows the voltage that must be applied to the motor to operate.
3. **Electrical current (current)**: Determines the amount of electrical current that the motor draws when it is running.
4. ** Reverse Speed (Speed) **: The main speed of the writer is measured per minute (RPM) and determines the speed of the rotor.
5. **Frequency (Frequency)**: It is measured in Hertz (Hz) and determines the frequency of the electrical current used.
6. **Motor Type (Type)**: Specifies the type of motor (such as AC DC motor or DC motor).
7. **Power Factor**: Shows the electrical details of the motor.
8. **Protection Degree (IP Rating)**: The level of protection against harmful factors such as the outdoors.
This information helps to use the engine correctly and its technical specifications.
