Abstract
A method of determining an out-of-balance condition of an electronically controlled motor. The method includes: determining a plurality of parameters based on measurements taken from the electronically controlled motor, and calculating a composite score by combining said plurality of parameters into a mathematical transfer function. The mathematical transfer function includes a non-zero weighting factor for each of the plurality of parameters.

A method of determining an out-of-balance condition of an electronically controlled motor, the method comprising:
- determining a plurality of parameters based on measurements taken from the electronically controlled motor;
- and
- calculating a composite score by combining said plurality of parameters into a mathematical transfer function, said mathematical transfer function including a non-zero weighting factor for each of said plurality of parameters.
A system for determining an out-of-balance condition in an electronically controlled motor, the system comprising:
- a controller;
- a motor interfacing with said controller;
- and
- a scoring sequence resident on said controller, said scoring sequence receiving a plurality of parameters from said motor and calculating a composite score by combining said plurality of parameters into a mathematical transfer function, said mathematical transfer function including a non-zero weighting factor for each of said plurality of parameters, said composite score providing a measure of an out-of-balance condition in said motor.
A method of determining an out-of-balance condition of an electronically controlled motor, the method comprising:
