A 20yr 25hp 585rpm 480v delta 3 phase induction motor, rewound 6 yrs ago supposely, new vfd installation. we are having sporadic random vfd failures. I am thinking this motor was not wound to handle inverter rated applications. Can Aged Motors be properly reworked to todays inverter standards????? What type of tests of the motor can I perform, to qualify this???
