System and method for performing a spin motor startup operation |
摘要 |
A system and method for controlling operation of a motor system that addresses the design challenges for the small form factor optical disk system. The present invention includes starting the operation of a motor including windings and a rotor; placing the motor in a first operational state; driving the motor from the first operational state to a second operational state; and sensing a variation in an electrical waveform induced by driving of the motor to determine a cycle period from which the speed of the motor can be determined.
