  • Method for gel curing a varnish of a stator assembly
    Patent number: 11588385
    Abstract: A method for gel curing a varnish of a stator assembly includes: applying an electrically-insulating material to a plurality of electrical conductors of a stator assembly; monitoring a temperature of the stator assembly using at least one temperature sensor; determining whether the temperature of the stator assembly has reached a target temperature; in response to determining that the temperature of the stator assembly is equal to the target temperature, heating the stator assembly using an induction heating element to maintain the temperature of the stator assembly at the target temperature for a predetermined amount of time; determining whether the temperature of the stator assembly is equal to the final target temperature; in response to determining that the target temperature is not equal to the final target temperature, increasing the target temperature by a predetermined amount of degrees.
