the System of Speed Adjustment for Permanent Magnet Brushless DC Motor
Abstract:With the development of Power Electronic Technique and the following appearance of many high capability semiconductor, such as GRT、MOSFET、IGBT. And some high quality permanent magnetic material also gives Direct Current Electromotor a good foundation, such as rare earth. As a result, Direct Current Electromotor is developing vigorously. In order to make Direct Current Electromotor more familiar ,I want to see the structure、principle 、control and the practical use of the Direct Current Electromotor. Especially, I spend a lot ink to study the electromotor’ principle, so I can make the control part more easily. And I also want to design an electromotor in order to throw the knowledge I have learnt into practice. At last, I have a dream that all buses’ motor can be replaced by Direct Current Electromotor, so that we can save more energy and make the world more beautiful.
