First Claim
Patent Images
1. A method for monitoring an AC induction motor, comprising:
- monitoring one or more characteristics of the AC induction motor;
producing one or more inputs from the characteristics;
supplying the one or more inputs to a motor controller;
using fuzzy logic to determine one or more outputs of the controller to the AC induction motor; and
controlling acceleration and deceleration of the AC induction motor to start and stop the AC induction motor by regulating the AC induction motor based on the one or more outputs of the controller determined using fuzzy logic.

Abstract
A system, method, and device for monitoring an AC induction motor are disclosed. The exemplary system provides the architecture of an intelligent motor controller. On one hand, the controller has self-commission and adaptive tuning capability and can provide smooth start and stop for motor driven systems. On the other hand, the controller can provide fault detection, power metering, and history data logging, to ensure motor operates under optimal conditions. The exemplary system may have one or more sensors for monitoring characteristics of the AC induction motor and producing one or more inputs from the characteristics.
