The motors of three-phase synchronous are uesd for dniving large machinerydemanding invanable speed. Forexample industnal fan.reciprocating compressor.Kibbler,water pump.rolling mill auxilixry drive,etc. They are characterized by ldading power factor that can ameliorate the factor of the net.reloiable operation,hifh of bigger over load multiple than the same three-phase AC asynchronous motors.otherw ise the loading changes.
Their voltage grade is 380V.660V,6KV,10KV......Number of poles is 6 to 24,power range is 200KW to 1800KW.
They are featured by advanced technology.reasonable structure,high insulation grad.good elecncal characteristic.reasonable operation and convenient installation &maintenance. Before it leaves the factory,all motors shall have passed strict electrical inspection and running test wish assured performances.
The motors have two construction types.salient pole and cryptic pole,and two mouning types,and horizontal type. The motors can be made two construction typed,one wish shaft and bearing(IM7311),the other without shaft and bearing (IM7311),The tyoe of cooling is often opening (IC01)and other types, The outer shell,s basic protection class is often IP00.also can be made of IP23 and other degrees, The insulation class is F. The temperature difference is measured by class B. The way of excitation is ststic excitation, If the consumer want other demand, the motorscan be made into special types with salt-fog moisture &mould-proof or for high elevation.
