Embodiment
Please refer to second figure, be the enforcement schematic diagram of the drive unit of motor of the present invention.Consult this figure, this drive unit 20 of the present invention is to be electrically connected on a motor 30, and can be in order to the rotation of this motor 30 of controlling and driving.
In present embodiment, this drive unit 20 mainly includes a transducer 21 and a selector 22, this transducer 21 can be accepted a nonelectrical energy source of supply 40 (for example being: luminous energy, heat energy, mechanical energy or chemical energy), and this nonelectrical energy source of supply is converted to one first electric energy to input to this selector 22.
This selector 22 is electrically connected on a power supply unit 50, and this power supply unit 50 can produce one second electric energy to input to this selector 22.
Above-mentioned selector 22 can be according to a feedback signal of being fed back by this motor 30 to select the output of this first electric energy or this second electric energy; In general, because this first electric energy is the electric energy through conversion, so its energy is less, export when being fit to these motor 30 low-speed runnings, and the maximum output valve of this second electric energy generally can be designed to drive the value of these motor 30 full-speed operations, is to desire at full speed or these selector 22 these second electric energy of output of Shi Keling that run up with this motor 30.
Please refer to the 3rd figure, be the detailed formation schematic diagram of this selector.Consult this figure, this selector 22 switches circuit 221, a comparison circuit 222 and a feedback circuit 223 by one to be formed, this commutation circuit 221 is electrically connected between this transducer 21, this power supply unit 50 and this motor 30,223 of this feedback circuits are electrically connected on this motor 30, and this comparison circuit 222 then is to be electrically connected between this commutation circuit 221 and this feedback circuit 223.
This commutation circuit 221 includes one first end points P1, one second end points P2 and one the 3rd end points P3, this first end points P1 is electrically connected on this transducer 21, this second end points P2 then is electrically connected on this power supply unit 50, the three end points P3 and then is electrically connected on this motor 30; The 3rd end points P3 is linked optionally with this first end points P1 or this second end points P2, when being connected in this first end points P1, can obtain this first electric energy from this transducer 21, and when being connected in this second end points P2, can obtain this second electric energy from this power supply unit 50.
This feedback circuit 223 can be obtained a feedback signal from this motor 30, this feedback signal can be a tach signal or is a current signal, and this feedback circuit can be converted to a voltage signal with this tach signal or this current signal, and this voltage signal is inputed to this comparison circuit 222.
