The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Sine-wave oscillators such as the Wien-bridge, state-variable, or quadrature oscillators, have an inherently undefined amplitude. Ideally, the poles of their feedback loop are on the jω-axis and the ...

Electronic Fuel Injection (EFI) is a solution that guarantees a low emission as well as a fuel consumption optimization, for small motors that, otherwise, can be very polluting. This fact underlines ...

I’ve been a Subversion (SVN) user going on 9 years now. It’s been a great solution for source control throughout my career and I’ve implemented it at each stop along the way. It’s easy, reliable, and ...
