a single phase motor is run from a power source with a singular distribution of alternating current electric power. ningbo zhongyi hydraulic motor co., ltd has the experience in produce piston motor,pg电子下载-pg电子游戏 ,gearbox,hydraulic steering unit,axial piston motor with quality assurance. so welcome to our web or call us. our web is www.zihyd.com/cn
this means that in the power supply, all of the voltages vary in unison. the typical characteristics for electric motors of single phase are that the current produces a pulsating rather than a rotating magnetic field and that an extra circuit is needed for starting this motion.
the currents in single phase motors reach their peak values simultaneously, making one phase. three phase systems, on the other hand, reach peak current values sequentially, making three stages. in comparison to three phase systems, these motors do not have the same high efficiency levels, but can last indefinitely with little maintenance.
there are many different types of motors available, each category defined by the method used to start the mechanism. these categories include the split phase motor, capacitor start/ induction run, permanent slip capacitor and the capacitor start/capacitor run.
the split phase motor, also referred to as induction start/ induction run, is one of the simplest electric motor designs of single phase. it features a start and a main winding, with the start winding having a smaller gage wire and fewer turnings. this difference creates resistance in the motor and causes a rotating field. the main winding is heavier and maintains the running of the motor.
