In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity.
The circle diagram (also known as Heyland diagram or Heyland circle) is the graphical representation of the performance of the electrical machine [1] [2] [3] drawn in terms of the locus of the machine's input voltage and current. [4] It was first conceived by Alexander Heyland in 1894 and Bernhard Arthur Behrend in 1895.
Piezoelectric devices can create sound or vibration from an electrical signal or create an electrical signal from sound or mechanical vibration. To become an electromechanical engineer, typical college courses involve mathematics, engineering, computer science, designing of machines, and other automotive classes that help gain skill in ...
Cross-section of switched reluctance machine with 6 stator and 4 rotor poles. Notice the concentrated windings on the stator poles. A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance.
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
