Types of DC Motors



the different types of DC motors:

DC Motors

Self-Excited: Generate their own magnetic field using a field winding connected in series (high torque, speed sensitive), parallel (constant speed, lower low-speed torque), or a combination (balance of both).
Series: High torque at low speeds, ideal for cranes, hoists.
Shunt: Constant speed, suitable for fans, pumps.
Compound: Combines series and shunt features, used in rolling mills, elevators.
Separately-Excited: Use a dedicated power source for the field winding, allowing for precise control of speed and torque. Ideal for high-precision applications.
Permanent Magnet: Utilize permanent magnets for the magnetic field, known for high efficiency, low maintenance, and compact size. Commonly used in fans, pumps, servo motors.
Key Takeaways:

The choice of DC motor depends heavily on the specific application requirements, such as speed, torque, and load variations.
Each type has unique advantages and disadvantages in terms of performance, controllability, and cost.

Electromagnetic Induction

Electromagnetic Induction  I can provide you with a brief overview of the topic and some key points that are typically covered in class 12 physics notes on electromagnetic induction: Electromagnetic Induction is a fundamental concept in physics, discovered by Michael Faraday in the 19th century. It deals with the generation of an electromotive force (EMF) or voltage in a closed circuit due to a change in magnetic flux through the circuit. Key points often covered in class 12 notes on electromagnetic induction may include: 1. Faraday's Law: It states that the induced electromotive force (EMF) in a closed circuit is directly proportional to the rate of change of magnetic flux through the circuit. Mathematically, this is expressed as EMF = -d(Φ)/dt, where EMF is the induced voltage, Φ is the magnetic flux, and dt is the change in time. 2. Lenz's Law: Lenz's law is a consequence of Faraday's law and states that the direction of the induced current will be such that it oppos...

3 Phase Induction Motor: Construction and Working Principle

Image
3 - Phase Induction Motor 3 Phase Induction Motor: Construction and Working Principle A three-phase induction motor is a common type of electric motor used in various industrial and commercial applications. It operates on the principles of electromagnetic induction and consists of two main parts: the stator and the rotor. Here's an overview of the construction and working principle of a three-phase induction motor: Construction: Stator: The stator is the stationary part of the motor and consists of laminated iron cores with slots to hold the stator windings. The stator windings are typically designed for three-phase AC power and are evenly spaced around the inner circumference of the motor. Rotor: The rotor is the rotating part of the motor. There are two main types of rotors used in three-phase induction motors: Squirrel Cage Rotor: This is the most common type of rotor. It consists of a set of laminated iron cores with aluminum or copper bars (short-circuited conductors) arranged...
