Electric motors can be categorized into three main segments: AC motors, DC motors, and special purpose motors.

DC Motors

DC motors come in various types, including:

1. 1. DC Shunt Motor: This type of motor operates on DC power, and its armature windings and field windings are connected in parallel, also known as a shunt. It is commonly referred to as a shunt wound DC motor. DC shunt motors are used in a wide range of applications, and you can learn more about their working and applications by referring to this link.
   2. Separately Excited Motor: In a separately excited motor, the stator and rotor can be connected to different power supplies, allowing for independent control of the shunt and armature windings to generate the desired flux.
   3. DC Series Motor: In a DC series motor, the rotor windings are connected in series. The operation of this type of motor is based on the electromagnetic law that states that a conductor with a magnetic field around it will interact with an external field to generate rotational motion. DC series motors are commonly used in starter motors for elevators and cars. You can learn more about their working and applications by referring to this link.

1. PMDC Motor: PMDC stands for “Permanent Magnet DC motor”. It is a type of DC motor that has a permanent magnet built into it to create the necessary magnetic field for motor operation. You can learn more about PMDC motors, including their construction, working, and applications, by referring to this link.
2. DC Compound Motor: A DC compound motor is a hybrid of DC series and shunt motors. It has both series and shunt windings in its stator and rotor, connected in a compound manner. The series winding typically has fewer windings of wider copper wire, providing a low resistance path, while the shunt winding has multiple windings of copper wire to receive the full input voltage.

AC Motors

AC motors come in various types, including:

1. Synchronous Motor: The operation of a synchronous motor depends on a 3-phase power supply. The stator in the motor generates a field current that rotates at a stable speed based on the AC frequency, and the rotor rotates at the same speed as the stator current. Synchronous motors are used in automation, robotics, and other applications where high rotational accuracy is required. You can learn more about synchronous motors, including their types and applications, by referring to this link.
2. Induction Motor: An induction motor, also known as an asynchronous motor, operates at asynchronous speeds. It uses electromagnetic induction to convert electrical energy into mechanical energy. Based on the rotor construction, induction motors can be classified into two types: squirrel cage and phase wound. You can learn more about induction motors, including their types and advantages, by referring to this link.

Special Purpose Motors

Special purpose motors include various types such as:

1. Stepper Motor: A stepper motor provides step-wise revolution angles, as opposed to continuous revolutions. The rotor of a stepper motor rotates in discrete steps, such as 10 degrees per step in an 18-step cycle for a complete revolution. Stepper motors are used in applications such as plotters, circuit fabrication, process control equipment, and motion generators. You can learn more about stepper motors, including their types and applications, by referring to this link.
2. Brushless DC Motors: Brushless DC motors were developed to achieve higher performance in a smaller form factor compared to brushed DC motors. They are smaller and more efficient than AC motors, and they have a controller embedded in the motor to facilitate operation without a commutator and slip ring.
