Q:Elevator industry, the traction machine has permanent magnet synchronous motor and permanent magnet asynchronous motor two, what is the difference between them?

In general, there are old-fashioned elevator should be used mostly synchronous motor, because the synchronous machine mechanical characteristics and stability, but, nearly 20 years, asynchronous motor frequency drive has made rapid development, asynchronous motor characteristics of the software problem has been very good The application of the technology, such as direct torque control, makes the manufacturers claim that the characteristics of the asynchronous motor are equal to or higher than the characteristics of the synchronous motor. Therefore, the synchronous motor and the asynchronous motor are only two different periods and different application methods.
