Abstract
An electronic device may include a motor to operate at a first frequency during a first time period and to operate at a second frequency during a second time period, and an accelerometer to obtain first data relating to operation of the motor at the first frequency and to obtain second data relating to operation of the motor at the second frequency. The electronic device may also include a processor to determine a desired resonant frequency of the motor based on the first data and the second data.
