Electric motors make things go
Electric motors make things go. Better motors mean better go power. What constitutes “better” and what to do about it, is the subject of a great deal of investigation. Better motors generally mean 2 things, higher efficiency and greater torque produced for a given amount of input power.
Georg Simon Ohm und der elektrische Widerstand
Georg Simon Ohm erkannte den Zusammenhang zwischen Stromstärke, Spannung und Widerstand. Mit dem Ohmschen Gesetz legte er den Grundstein für Telegraphie, Elektronik und Mikroelektronik.
Faraday’s Law of Electromagnetic Induction
We have seen previously that when a DC current pass through a long straight conductor a magnetising force, H and a static magnetic field, B is developed around the wire. If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar magnet giving a distinct North and South pole.
AC Motor control - Frequency converter
A complete installation with a frequency converter controlled motor consists of a series of different components which should all be selected carefully for a given application.The components in an installation are selected according to the actual application, starting with selecting the right pump for the application.

Three-phase motors wiring diagrams and markings of terminals
The windings are connected in star(Y)-connection or in delta(Δ)-connection according to IEC 60034-8. This is done by wiring the terminal board as shown in the wiring diagram to the right. The marking of the terminal board is also defined in IEC 60034-8.
