The specific steps and methods of starting permanent magnet synchronous motor are introduced

introduction：Existing permanent magnet synchronous motor​At start-up，First you need to determine the position of the rotor。In the prior art, the following methods are used to determine the position of the motor rotor1.Forced positioning through the rotor，Method of reopening the loop starting。But when you use this method，The motor may reverse，Inversion is not allowed in many cases，Because its dangerous。And the start-up process is not reliable and smooth。2.Energize the motor in six steps，Method of redetecting the time of passing back electromotive force。However, this response time is slow，Long startup time。3.Startup based on other complex control algorithms and high cost hardware，however，These methods cost too much。
