Control system for synchronous electric motor
A control system for a synchronous electric motor controls the synchronous motor so that the phase of a current determined based on a magnetic pole position of a moving element of the motor may shift to a phase where maximum torque may be obtained. A magnetic pole position correcting section determines a magnetic pole position correction to be added to a relative magnetic pole position. In connection with a polarity change determining section which determines whether or not a polarity of an acceleration difference changes, a basic correction adjusting section switches computation between an incremental operation of incrementing a basic correction and a decremental operation of decrementing the basic correction by a correction increment/decrement. When the correction increment/decrement becomes a predetermined lower limit value B or less, the basic correction adjusting section stops the computation. The basic correction at that point is determined as a finally-determined magnetic pole position correction. |

High temperature direct coal fuel cell
The invention relates to direct conversion of coal into electricity in a high temperature electrochemical generator in a single step process. This novel concept promises nearly doubling the conversion efficiency of conventional coal-fired processes and offering near-zero emissions. The improved efficiency would mean that nearly half as much coal is mined and transported to the power plant, and half the greenhouse gases and other pollutants such as sulfur, mercury and dioxins are produced. It also offers several crucial distinctions from conventional coal-burning processes. Since the process does not involve the combustion of coal in air, it does not involve nitrogen and hence generates practically no NOx. Accordingly, there is also no latent heat lost to nitrogen. In this process, the oxygen necessary to oxidize coal is supplied through an ion selective ceramic membrane electrolyte. The resultant product stream primarily consists of CO2 and, hence, it is easier and cheaper to capture and sequester, compared to waste streams from conventional combustion processes where CO2 ordinarily constitutes about 15-20% of the flue stream, in which case it may first be separated from other constituents before sequestration. |
