253 - Analysis of an Induction Generator

253 - Analysis of an Induction Generator

Induction machines are based on the double field revolving theory. An induction machine also operates using the principle of slip. Slip is defined as the difference between synchronous speed and operating speed where the synchronous speed is the speed of the rotating field. Thus depending on the slip an induction machine has 2 operating modes. When the slip is positive it acts as an induction motor and when it is negative it acts as an induction generator.

251 - Vibration Analysis of an Alternator

251 - Vibration Analysis of an Alternator

Electromagnetic force in the form of an electromagnetic excitation force acting on a motor or an alternator causes vibration and noise. Vibration and noise also are produced when this electromagnetic excitation force resonates with an eigenmode of the motor. In order to accurately evaluate this phenomenon, it is necessary to grasp each frequency and spatial mode in detail about the electromagnetic force and eigenmodes of the motor.

216 - Simulation of a Claw-Pole Type Alternator Using a Control Simulator and JMAG-RT

216 - Simulation of a Claw-Pole Type Alternator Using a Control Simulator and JMAG-RT

The demand for low fuel consumption of automobiles has been increasing every year, and types of auxiliary systems and devices such as power steering and cooling pumps are being electrified to support this. For this reason, the amount of electricity used has increased every year for general gasoline-powered vehicles, and the demand for higher output power for alternators which supply electricity is increasing.

212 - AC Loss Analysis of a Claw Pole Alternator

212 - AC Loss Analysis of a Claw Pole Alternator

Electric Machines are affected primarily by 3 types of losses. Iron losses in steel lamination sheets, joule losses in the conducting components and joule losses in coils. When we primarily focus on AC losses in coils, one way to reduce them is by using a "Bar winding". Bar winding is used large conductor bars, so this improves fill factor and reduces DC resistance which in turn reduce DC losses.

121 - Output Analysis of a Salient-Pole Synchronous Generator

121 - Output Analysis of a Salient-Pole Synchronous Generator

Salient-pole synchronous generators are used in hydroelectric generators and the like. Power is generated in the stator coils (armature) by a field current flowing in the rotor coils and the rotor rotating.
Reactions occur between the field current and the armature current that either strengthen or weaken...

25 - Analysis of a Claw Pole Alternator

25 - Analysis of a Claw Pole Alternator

Demand for high fuel efficiency in vehicles has been growing every year, and auxiliary machines like power steering and coolant pumps have been switching to electrical operation to support those needs. This is why the amount of electrical power being used in typical gasoline vehicles is increasing with each passing year,...
