Types of AC Machines:
Synchronous Machines:
- Synchronous Motor: Converts AC electrical energy into mechanical energy at a constant speed synchronized with the AC power supply frequency.
- Synchronous Generator: Converts mechanical energy into AC electrical energy, maintaining a constant voltage and frequency in the output.
Asynchronous Machines (Induction Machines):
- Three-Phase Induction Motor: The most common type of AC motor, which operates based on the principle of electromagnetic induction.
- Single-Phase Induction Motor: Used in smaller applications, such as fans and appliances.
- Linear Induction Motor: Creates linear motion instead of rotational motion.
Special Types:
- Brushless DC Motor (BLDC): A type of synchronous motor that uses electronic commutation to eliminate the need for mechanical brushes.
- Permanent Magnet Synchronous Motor (PMSM): A synchronous motor that uses permanent magnets instead of field windings for excitation.
- Reluctance Motor: A synchronous motor that operates based on the reluctance of the rotor to align with the rotating magnetic field.
- Switched Reluctance Motor (SRM): A type of reluctance motor that uses electronic switching to control the magnetic field.
- Hybrid Motors: Combinations of different AC machine types, such as brushless DC motors with permanent magnets (BLDC PM).
