The instruction of AC PM door motor The 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… Parameters TypePowerCurrentRotate speedVoltageFrequencyTorqueLoadInstallationMJ136-362W1.1A165rmp65V22Hz3.6 Nm120-180KgBottom /FlangeMJY136-586W1.0A165rmp80V22Hz5.0 Nm240-320KgBottom/Flange The functions of AC PM door motor --It belongs to Servo motor.
