DJseriesHysteresisSynchronousMotor

Hysteresis synchronousmotor isa small powersynchronousmotor that isstarted and operated bythe hysteresistorque generated on the rotor.

Hysteresismotor hastheadvantagesofsimplestructure,easystartupand lownoise,but itstransient stabilityis poorand itsefficiencyis low.In the occasionof requiringlower speed,gearisneeded to reduce speed.

The hysteresismotor hasa large starting torque,can be pulled in synchronouslyand stably operatedina synchronous state,hasa simple structure,reliable operation,highmechanical strength,is suitable forhigh-speed operation,and hasa small startingcurrent andlowelectromagneticnoise.

Itisespeciallysuitablefordrivingloadswithlargerotationalinertia, constant speed,frequent startingand constant torque.Typical applicationarea:valvecontrol.

InstallationNotes

This valve is compatiblewith Siemensactuators.
Below thevalve stem is thevalveclosing direction.
Before installing the valve,ensure that thepipeline iscleanandfree of oxide scale, metalplatesandotherdebrisleftduringwelding.
Thepipes must be concentric when connected to thevalvebodyand not subjectto vibration.The direction of water flowshould be the sameasthat marked on the valve body.
●When the driveris installed verticallyonthe valvebody,avoid installing thedriverunder thevalve,and leaveenough space forroutine maintenance (such as removing the driver). Whenmaintaining thevalve,thepowermust becut off orisolated.The watersystem should not be under pressure.
