Motor A.{Mr Adams} Resistance of Teazer winding, rewound with 30 turns of 17 SWG DCC wire, in position with main winding on original type pole cores. (pole cores to D70327). Resistance of teazer winding (measured) = .310ω at 19°C. Resistance of teazer winding (calculated) = .343ω at 45°C. Resistance of main winding was checked and found to be .015ω at 18°C. Insulation of both windings OK. Signed: C.A.P. This Sheet must be filed on completion of the work. | ||
