Abstract:
One example is a system for controlling a motor during startup. The system includes measurement logic, pattern detection logic, and mode logic. The measurement logic monitors a back-electromotive force (BEMF) signal representing a BEMF of an electric motor and the pattern detection logic monitors this signal to detect instances of the monitored BEMF signal exhibiting a predetermined pattern. The mode logic enables control of the electric motor according to a plurality of modes of control. In some examples, the mode logic initially employs a first mode of control and switches from the first mode of control to a second mode of control in response to the pattern detection logic detecting that a BEMF signal exhibits the predetermined pattern over a plurality of commutation states.

Claim (Index 20):
A system, comprising:\n a sensor that provides a sensor signal representing a measure of back electromotive force (BEMF) for each floating phase of a multi-phase electric motor; a controller having outputs to provide control signals to control operation of the multi-phase electric motor, the controller being configured to:\n utilize a first mode of control that is not BEMF-based to initially control the multi-phase electric motor; \n detect each occurrence of a pattern in the sensor signal, the pattern in the sensor signal including crossing a predetermined signal value during at least one commutation state of the multi-phase electric motor; \n switch from the first mode of control to a second mode of control that is BEMF-based in response to detecting occurrences of the pattern over a plurality of consecutive commutation states, \n count a number of times the BEMF sensor signal crosses the predetermined signal value over the plurality of consecutive commutation states; \n reset the count in response to detecting that the BEMF sensor signal does not cross the predetermined signal value during at least one of the plurality of consecutive commutation states; and \n switch the multi-phase electric motor from the first mode of control to the second mode of control if the count exceeds a predetermined threshold.
