s to expect just start developing, still is two kinds of structure types up to now in the meantime keep both. Though new of the hybrid type tread into the electric motor pletely. May act for the type electric motor, but the whole machine of the type electric motor acquire to apply over a long period of time, to its technique also pare in order to acquaint with, especially typical of hybrid type39。s control of the actuator PLC of the electrical engineering power pulse, volt, several Anne arrive several ten several Anne s drive an ability, the exportation of general PLC connects to have to certainly drive an ability, but inside usual transistor flow exportation to connect an oscular load ability only for ten several arrive several ten volts, several ten arrive several 100 million Anne but tread to then have several request into the electrical engineering to the power ten arrive up 100 volts, several Anne arrive several ten Anne s drive an abilityso should adopt an actuator to output the pulse carry on enlarging.The development trend of 5 domestic and international electrical engineering: (1)、continue along small scaled direction development turned along with electric motor application the realm open widely and each kind of whole machine is continuously small scaled to turn, the electric motor which requests with its kit have to also more and more small, at 57, the electric motor of 42 machine seat numbers applies many after years, now its machine seat number to 39,35,30,25 directions get down extension.(2 )、right nesses of electric motors carry on prehensive design namely turn soon position to spread a feeling machine, decelerate the wheel gear etc. and electric motor essence to synthesize design together, so make it be able to constitute 1 to shut wreath system expediently, as a result have one more superior control function.(3)、to five mutually with three mutually the electric motor direction develop,Be suffused with currently applied of two mutually with four mutually the electric motor, its vibration and voice are bigger, but five mutually with three mutually the electric motor have advantage but in regard to these two kinds of electric motors, five mutually the electric motor drive electric circuit pare three mutually electric motor plications, so three mutually the function price of electric motor system than want than five mutually the electric motor is a li
