Abstract

A method of insulating a coil of an electrical machine includes applying an insulating varnish to a coil of conductive wire. The varnish includes (i) a resin; (ii) a first catalyst having a first activation temperature, the first catalyst being active at room temperature; and (iii) a second catalyst with a second activation temperature substantially higher than the first activation temperature. The varnish is allowed to partially cure at room temperature. The coil is mounted to a yoke to form a rotor of the electrical machine. The rotor is operated so as to heat the coil and activate the second catalyst to complete curing of the varnish.
