Abstract: The invention belongs to a novel replaceable brushless direct current motor circuit device capable of generating electricity, continuously supplying power, and power supply for deceleration/braking. A power generating device, a power saving device and a micro-control device can be disposed outside a brushless direct current motor to form a replaceable recycle power brushless direct current motor. The replaceable recycle power brushless direct current motor is provided with a multi-pole direct current main electromagnet, an N-pole main magnet and an S-pole main magnet in a brushless direct current motor. A sub-electromagnet, an N-pole sub-magnet and an S-pole sub-magnet are disposed inside the power generating device. A rectification boosting circuit, an IV conversion circuit, a voltage differentiator, a voltage control current limiting circuit and a power parallel circuit are disposed inside the power saving device. A microprocessor circuit and a switch are disposed inside the micro-control device. The replaceable recycle power brushless direct current motor utilizes a direct current power supply to drive the N-pole and S-pole main magnets to rotate through the multi-pole direct current main electromagnet and to drive a load to work (power supply main electromagnet). The replaceable recycle power brushless direct current motor further drives the N-pole and S-pole sub-magnets inside the power generating device to rotate through the N-pole and S-pole main magnets, and generates power through the sub-electromagnet (the sub-electromagnet generating power) inside the power generating device. The generated power is further powered by the power saving device via the direct current power supply, and the direct current power supply can save power (power generation and power supply). The micro-control device can change the operation control so that the direct current power supply drives the N-pole and S-pole main magnets to rotate through the multi-pole direct current main electromagnet and drives the load to work. Alternatively, the micro-control device can also change the operation control so that the direct current power supply drives the N-pole and S-pole sub-magnets to reversely rotate through the sub-electromagnet so as to slow down the load working (supplying power to the sub-electromagnet and supplying power to decelerate and brake). In addition, the N-pole and S-pole sub-magnets and the N-pole and S-pole main magnets can be mechanically connected to generate power for the N-pole and S-pole sub-magnets, and the N-pole and S-pole main magnets drive the load, or the N-pole and S-pole sub-magnets reversely rotate and the N-pole and S-pole main magnets slowly drive the load. The N-pole and S-pole sub-magnets and the N-pole and S-pole main magnets can also be mechanically separated to individually drive the load for the N-pole and S-pole main magnets alone, or to replace the N-pole and S-pole sub-magnets (the power generating device can be replaced). Accordingly, in the invention, the replaceable recycle power brushless direct current motor constituted by a brushless direct current motor, a power generating device, a power saving device and a micro-control device can supply power to the brushless direct current motor in cooperation with the direct current motor power supply so that the power saving device can save power from the direct current power supply to the brushless direct current motor. Therefore, the micro-control device can supply normal DC power to the brushless direct current motor. Alternatively, the micro-control device can increase the direct current power supply to the brushless direct current motor for motor deceleration. By utilizing this novel motor power generation and power supply deceleration concept, it can achieve the multiple power supply function and purpose of the brushless direct current motor that can save and supply power, normally supply power, or supply power for deceleration.
