Abstract: A motor controller integrated circuit (IC) includes a storage device containing software, and a processor core. The processor core has an output adapted to be coupled to a motor. The processor core is configured to execute the software to operate the motor in an open-loop control, calculate first and second orthogonal components of a back electromotive force (BEMF), calculate a total BEMF value, and determine that the first orthogonal component is within a threshold of the total BEMF value. The processor core is further configured to, responsive to the first orthogonal component being within the threshold of the total BEMF value, operate the motor in a closed-loop control.

Abstract: Embodiments of the present disclosure include a motor controller with a processor and a machine readable medium. The medium includes instructions that, when loaded and executed by the processor, cause the processor to receive an estimated or sensed speed of a motor, extract a mechanical frequency component from the estimated or sensed speed, transform the mechanical frequency into direct quadrature (DQ) domain at the mechanical frequency, control the mechanical frequency to zero, and generate a dampening signal for torque based upon the controlled mechanical frequency.

Abstract: Example systems and processes control transition of an electric motor from open-loop operation to closed-loop operation by detecting zero-crossing (ZC) locations of the back-electromotive force (BEMF). The rotor angle of the electric motor is changed, e.g., by changing acceleration of the electric motor to correct a phase difference based on the detected ZC locations and an open-loop profile of the electric motor. Detected ZC locations may be used to identify ZC-detected-based commutation points, and each detected ZC location may be used to update a next commutation point. During the control process the open-loop profile is updated. Transition may occur when a set number of ZC-detection-based commutation points are sufficiently aligned with corresponding updated commutation points, or such alignment is maintained for at least one electrical cycle.
