摘要： The present invention provides a motor controller having one or more multi-functional pins. The motor controller includes a plurality of pins but does not include a dedicated pin for transmitting a clock signal and a dedicated pin for transmitting a motor specification database setting signal, wherein the clock signal and the motor specification database setting signal are for setting motor specification data. The clock signal and the motor specification database setting signal are transmitted through two of the plural pins which are multi-functional function pins shared by other functions in a normal operation mode. In a motor specification database setting mode, these multi-functional function pins are used for transmitting the clock signal and the motor specification database setting signal. In the normal operation mode, these multi-functional function pins are used for other functions.

摘要： A multi-phase motor control method controls a multi-phase motor which includes multiple nodes respectively receiving a corresponding number of driving voltage signals to control a rotation of a rotor. The motor control method includes: sensing a signal phase of a current signal corresponding to at least one node, for example by sensing a zero-crossing point of the current signal; determining a reference phase for the current signal; calculating a phase difference between the signal phase and the reference phase; and controlling a phase switching frequency of the stator according to the phase difference, such that the signal phase is close to or in phase with the reference phase, to thereby obtain an optimum rotation speed of the rotor corresponding to a given driving voltage. The present invention also provides a multi-phase motor control device using the motor control method.
