DL THREE PHASE FLANGED MOTOR Features Frame Size Range: H80~H355 Housing Material: Frame, flange and bracket, grey cast iron, conduit box-steel Standard Mounting Construction:IEC60034-7 Protect Enclosed Class:IP55 (IEC60034-5) Cooling Method: IC411 (IEC60034-6) The special winding design can work for multivoltages (50Hz or 60Hz) Can withstand 1.5 times of the rated current for 2 minutes (IEC60034-1) Anti-condensation heater is available. PTC or Pt100 thermistor are available to protect the winding and bearing.
Standard 3-phase motors can be connected using the star of delta method. Star connection is achieved by wiring W2,U2, V2 to each other; and U1, V1, W1 leads to voltage supply. Delta connection is achieved by wiring the end of a phase to the head of another.
Insulation Classification The motors have insulation class F while the temperature rise is for class B ensuring a longer service life. Class H insulation motors can be manufactured at the customer’s request. Under specified measuring conditions in accordance with IEC 60034-1 standard, insulation class F for an electric motor means that at the ambient temperature of 400C the temperature rise of its windings may be maximum 165K with the additional temperature margin of 10K.
