This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

The average efficiency of an internal combustion engine in real-world operation is measured at around 20 percent. 80 percent is lost as waste heat, of which only a small proportion is useful in winter ...
