Product introductionintroduction
Original sentence: "There are many types of motors, and it is necessary to classify them rationally in order to choose them according to their purpose and to be able to explain them to others in a way that they can understand or relate to. There are four types of motor classification methods.
① Classification based on conversion principle (electromagnetic motor, electrostatic motor, hypersonic motor)
② Classification based on power source (direct current power source, single-phase alternating current power source, three-phase alternating current power source)
③ Classification based on rotation method (determining the speed element/reverse rotation)
④ Classification based on structure (combination of rotating and stationary parts)
The classification method varies depending on the perspective from which the motor is viewed. The classification methods listed above are from the perspective of the manufacturer and do not meet the simplicity and convenience of use required by users.
Therefore, in order to facilitate understanding, this book has re-classified motors (direct current motor Figure 1.3) based on the classification mentioned above. We will introduce the characteristics of various motors according to this classification method in subsequent chapters."
