WebA direct-current (DC) generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. The basic principles of operation are the same as those for synchronous generators. Voltage is induced in coils by the rate of change of the magnetic field through the coils as the machine rotates. This induced voltage is inherently … WebView Shane Long, Ph.D. P.Eng.’s profile on LinkedIn, the world’s largest professional community. Shane has 5 jobs listed on their profile.
