Basic features of electrical engineering, the electromagnetic field, electrical metrology, and power electronics include the construction, modes of operation, fields of application, and selection of transformers. This covers direct current, asynchronous and synchronous machines, speed adjustment of electric motors, pole-changing motors, and converter-fed three-phase asynchronous machines. It also includes alternating current motors, motor vehicle generators, stepper motors, electronic motors, permanent magnet motors, linear motors, and electric shafts. The interaction of motors and driven machines, selection criteria for motors, and noise measurement and simulation are discussed, along with losses, heating and cooling under environmental aspects, and life cycle costs of electric drives. Additionally, the dynamic behavior of rotating electric machines, including causes, effects, representation, and consideration, is covered, as well as the simulation of electric machines for design and optimization.
