Abstract: A controller for a brushless motor that includes an input for receiving an analog signal, an analog-to-digital converter (ADC) for sampling the analog signal, and a processor. The processor starts the ADC during a first electrical half-cycle and reads the ADC during a second electrical half-cycle of the motor. Additionally, a motor system that includes the controller.

Abstract: A control system for an electric machine, the control system including a position sensor and a drive controller. The drive controller generates one or more control signals for exciting a winding of the electric machine in response to edges of a signal output by the position sensor. Moreover, the drive controller generates control signals in response to an edge that occurs within a time window. The time window starts at a time when control signals are generated and has a length less than the electrical half-cycle period.

Abstract: A control system for an electric machine, the control system including a position sensor and a drive controller. The drive controller generates one or more control signals for use in exciting a winding of the electric machine. Control signals for each electrical half-cycle of one mechanical cycle are generated by the drive controller in response to a single edge of a signal output by the position-sensor.
