摘要： A back EMF measuring method for multi-phase BLDC motor is proposed, which includes a driving process and a measuring process. The driving process energizes a plurality of phase windings of a detected motor by driving signals generated by a computing unit to rotate a rotor of the detected motor to a predetermined speed. The measuring process selects one of the phase windings as a target phase winding, continuously sends the driving signals to the phase windings other than the target phase winding but stops the driving signal sent to the target phase winding by the computing unit, and measures the back EMF of the target phase winding by a signal sensing unit.

摘要： A printed monopole smart antenna is provided. The smart antenna includes a monopole antenna having a plane for receiving and transmitting a signal, two conductors for directing and/or reflecting the signal to the monopole antenna respectively, and a circuit device electrically connected between the first and second conductors, for selectively switching the first and second conductors to determine an operation mode of the smart antenna. The smart antenna further has at least a groove in the ground for concentrating the current distribution and solving the influence of the antenna gain to the ground size. The sequence of the antenna pattern of the smart antenna is randomly arranged, depending on user's situation. When a plurality of printed monopole smart antennas are disposed on different directions of the WLAN AP/router, the omnidirectional radiation pattern will be obtained and the antenna gain will be increased.
