Losses in DC Machine- Types of Losses
Electric rotating machines are used for the conversion of energy. The motor converts electrical energy into mechanical energy, and the generator converts mechanical energy into … Read more
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;
Electric rotating machines are used for the conversion of energy. The motor converts electrical energy into mechanical energy, and the generator converts mechanical energy into … Read more
What is DC Motor? DC motor or Direct Current Motor converts electrical energy into mechanical energy. It is used to drive the mechanical loads. The … Read more
The rotor of the slip ring induction motor is connected to the external resistances. When the motor is started, the total external resistance gets added … Read more
The stator can either have a star or delta connection. Many motors have a winding scheme and coils with six connections that connect the windings … Read more
Why Pressure Relief Device(PRD) for Oil Filled Transformer? The winding of the transformer is housed in the transformer oil tank. The oil is used in … Read more
This article describes why DC is not used in transformers. The transformer functions on the principle of Faraday’s Law of electromagnetic induction. When AC is … Read more
Induction motor as a rotating transformer: The rotor of the squirrel cage induction motor is short-circuited by end rings. When a three-phase supply is fed to … Read more
An induction motor is called an asynchronous motor because the actual speed of the motor is not equal to the synchronous speed of the motor. The synchronous … Read more
A rotating magnetic field is produced when the three-phase supply is fed to the stator. The magnetic field travels the air gap length and cuts … Read more
Synchronous Speed When three phases which are 120 degree-electrical apart are fed to the stator winding of the induction motor, a rotating magnetic field is … Read more
