Slip Speed in an Induction Motor
A rotating magnetic field is produced when three phase supply is fed to stator of an induction motor. The rotating magnetic field has constant magnitude
Machines
An electrical machine converts mechanical energy into electrical energy or vice versa. The transformer is also an electrical machine which transform the voltage without changing the frequency. We will discuss about the;
- DC Motor
- DC generator
- Induction Motor
- Transformer
- Electrical drives
- Alternator or synchronous generator
Single Phase Transformer and Application of Single Phase Transformer
The transformer transforms voltage from one level to another without changing the power and frequency. The transformer is static electrical equipment, and it does not
Ideal Transformer-Properties, Phasor Diagram, Working
What is an Ideal Transformer? An ideal transformer is free from all losses. It has zero copper and iron loss and zero leakage flux, and
Shell Type Transformer- Construction, Working & Applications
The HV and LV winding is wound around the central limb. The central limb carries the entire flux (Ф ). The flux (Ф ) divides into two equal part and thus each side limbs carries the half (Ф/2 ) of the total flux(Ф ). As a result, cross section area of the central limb is two times of the side limbs area.The arrangement of the winding around the central limb is as given below.
Transformer Ratings- Formulas and Solved Problems
The maximum current a transformer can deliver to loads at the rated voltage is known as a transformer rating. It is expressed in VA, kVA,
Voltage Regulation of Transformer-Definition, Formula
What is the Voltage Regulation of a Transformer? Voltage regulation of the transformer is defined as the percentage change in the transformer’s secondary voltage from
Open Delta Connection of Transformer
When two single-phase transformer is connected in an open delta connection, the arrangement can provide a three-phase supply to the load. The open delta connection
Core Type Transformer – Construction & Working
The transformer can be categorized into core type and the shell type.In a core type transformer the winding encircles the core whereas in a shell type transformer the core encircles the winding. The winding encircles the core of a transformer. The Single phase transformer has two limbs and three phase transformer has three limbs.
Air Gap Power in Induction Motor
Air gap power in an induction motor is the output power of the stator or input power to the rotor. The electrical power fed to
Why Starting Torque of Squirrel Cage Induction Motor is Low?
The starting torque of an induction motor is very low compared to its rated torque. The torque of an induction motor depends on the rotor
