摘要： Continuous monitoring and fault diagnosis of rotating machinery during variable speed operation is performed using only a position feedback signal. The position sensor generates a periodic waveform having multiple pulses per revolution of the machine. A circuit is included to detect, for example, a zero crossing or edge of the periodic waveform. At each detected zero crossing or edge, the time and position of the event is stored in memory. Other data, such as the current in the motor, may also be sampled and stored in memory. Because the sampled data is triggered by repeated feature of the position feedback signal, the sampled data is in a stationary reference frame in the position domain. Frequency analysis is performed on the sampled data, and the frequency components present in either the sampled signal are analyzed to identify the presence of a fault in the rotating machinery.

摘要： A motor controller employs absolute encoder signals to periodically assess the existence of cumulative error in a position signal derived from an incremental encoder signal. In one embodiment the absolute encoder signals are extracted from commutation switches of the motor eliminating the need for a separate absolute encoder.

摘要： A system and method are provided for filtering noise from a pulsed input signal comprising cyclically producing a change in an output signal only if changes in an input signal occur at least a desired time after a respective immediately previous change in the input signal, and otherwise rejecting the changes in the input signal; and counting the rejected changes in the input signal. More than one duration or frequency may be used for the filtering, enabling classification of noise by frequency. Resulting counts may be used to determine rates of occurrence of noise for evaluation of performance of equipment, installation of the equipment, and changes in performance over time.

摘要： A motor control system uses an incremental encoder that provides a signal indicative of motor position. If an illegal state change is detected in the same sampling interval, an error event is recorded and an error counter is incremented. When the number of counts exceeds a pre-determined threshold, the motor is disabled so that appropriate corrective action can be taken.
