Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...

Recently I have seen a few interesting articles on viable cold fusion; the combining of atoms at room like temperatures to create boundless energy. Now...

Request to look at induction motor starting time have come up a few times on the site. Hopefully in this post, I give you guys some idea on how to calculate...

The fundamental component of any analogue computer is the operational amplifier, or op amp. An operational amplifier (often called an op-amp,) is a high...

Collection of links to various places with useful motor information. I’ll try and return to the page every now and again to update it with any motor notes...

Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...

Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
