### Electrical Machine
#### 1. **What is an Electrical Machine?**
- An electrical machine is a device that converts electrical energy into
mechanical energy (motor) or mechanical energy into electrical energy
(generator).
- Examples: Motors, Generators, Transformers.
#### 2. **Types of Electrical Machines:**
- **Motors**: Convert electrical energy into mechanical energy.
- Example: Fans, Washing Machines, Electric Cars.
- **Generators**: Convert mechanical energy into electrical energy.
- Example: Power Plants, Wind Turbines.
- **Transformers**: Transfer electrical energy between circuits without
changing frequency.
- Example: Step-up and Step-down Transformers in power distribution.
#### 3. **Basic Working Principle:**
- **Motors**: Work on the principle of electromagnetic induction. When
current flows through a coil in a magnetic field, it produces motion.
- **Generators**: Work on Faraday's Law of Electromagnetic Induction.
When a coil rotates in a magnetic field, it generates electricity.
- **Transformers**: Work on mutual induction. They transfer energy
between two coils (primary and secondary) using a magnetic field.
#### 4. **Key Components:**
- **Stator**: Stationary part of the machine.
- **Rotor**: Rotating part of the machine.
- **Coils/Windings**: Conductors that carry current.
