NettetWinding insulation and maintenance9/259 process of impregnation is therefore termed ‘resin-rich’ insulation. The completed formed wound stator is then heated to remove trapped moisture and finally impregnated in varnish class F or H as required. It may be simple dipping, roll impregnation (rotating in impregnating varnish for 1/ Nettet7. okt. 2024 · At the end of the cycle, remove and pressure-wash the stators and rotors, and then dry them thoroughly in a bake oven or temporary field oven (see Figure 3). Finally, test the insulation resistance to ground. If the test results are acceptable, apply a dip-and-bake varnish treatment before reassembling the motor.

The main concern in this step is the affinity between the wire enamel and binding varnish. A practice of mixing a lubricant with the enamel to make its surface more slippery has been adopted to facilitate wire winding and satisfy objectives such as making motors smaller and the winding process faster. meredith whiteside od

NettetRotor Winding. In a motor, the rotating part is known as the rotor. The rotor includes the rotor winding as well as rotor core. The rotor winding is energized by the DC supply. The rotor can be classified into two types … Nettet25. feb. 2024 · A high-grade solvent-less epoxy base varnish is used to impregnate the component, and it will maintain a 100% solid after curing in a bake oven. The Vacuum … NettetVacuum Pressure Impregnation (V.P.I) is a process by which a fully wound electric apparatus stator or rotor is completely submerged in a Resin. Through a combination of dry and wet vacuum and pressure cycles, the resin is assimilated throughout the insulation system.
