elevator door motor

The instruction of AC PM door motorThe AC PM Synchronous motor, which appears in recently years, is a leap in the elevator industry. PM motor’s principle that converts electricity to mechanical work by electromagnetic induction. It ‘s different from the A.C. motor, brushless D.C./A.C. motor and PM low speed motor. It is widely used on elevator door, car door, automatic door,Platform Screen Door and cold storage door…ParametersTypePowerCurrentRotate speedVoltageFrequencyTorqueLoadInstallationMJ136-362W1.1A165rmp65V22Hz3.6 Nm120-180KgBottom /FlangeMJY136-586W1.0A165rmp80V22Hz5.0 Nm240-320KgBottom/FlangeThe functions of AC PM door motor--It belongs to Servo motor. The speed signal in closed loop vector control.--Low speed, but high torque--Door Width automatic learning--Positions of the elevator's door could be set arbitrarily--Save your cost, it needs no the Position Switch and Speed Reducing Switch--Direct drive, reduce the troubleThe comparison with other door motorAC PM Synchronous MotorAC Asynchronous motorBrushless DC MotorDrive directlyableUnable-- it needs reducing apparatusUnable--it needs reducing apparatusSpeed points64≤4Speed curveSmoothNot smoothNot smoothDoor width auto-learningableUnable—under the open-loop controlUnable- under the open-loop controlTransformer and rectifierunnecessaryunnecessarynecessaryKeep constant torquewhen at zero speedableableunableLimit switchunnecessarynecessarynecessaryDoor system structuresimplecomplexcomplexFailure rateLowestlowerhighNoiselowhighhighSizesmallbigbigWeightlightheavyheavyThe instruction of the driver--Emerson---World famous brand.--It is inverter combine the drive system with the control system, it is never need Upper machine.--it owns the function of the door width auto-learning and positions could be set arbitrarily.--The open data interface ModbusThe instruction of encoder-- photoelectric encoder, which is different from magnetic coder.--the pulse number is 2500, which can guarantee control achieve precise and steady.Warranty--Our warranty is 12 months.--We will replace the products with new ones if the trouble is in the machine itself under the warranty.-- we are responsible for the maintenance free if the products are artificial damage under the warranty.
