A second DC power switch and a second power-saving power switch are provided; the replaceable energy-saving DC motor can change and control the microprocessor to make the first DC power switch inside the main switch to be a closed circuit for conduction, so that the main switch The first internal power-saving power switch is open to cut off the conduction, and the second DC power switch inside the auxiliary switch is closed to make conduction, so that the auxiliary switch The second power-saving power switch of the Ministry is open to cut off the conduction, so that the DC power can be supplied to the main coil rotor (power supply main coil) inside the brushed DC motor through the main brush, and the DC power can also be passed through the auxiliary The electric brush supplies power to the sub-coil rotor (supply sub-coil) inside the power generating device to drive the main coil rotor and the sub-coil rotor to rotate at the same time. In this way, the power generating device and the brushed DC motor can be mechanically connected for main coil rotation. The sub-powered rotation and the auxiliary coil rotor power-driven rotation, and the load is driven in a strengthened way (DC power supply strengthens the power supply motor). Using this kind of motor to change the power supply concept, it can achieve the "replaceable energy-saving DC motor" which can strengthen the power supply. Features.         As described in the “replaceable energy-saving DC motor” circuit device described in claim 3, the replaceable energy-saving DC motor can also change the operation of the microprocessor to make the first DC power switch inside the main switch to be closed for conduction, so that The first power-saving power switch inside the main switch is open to cut off the conduction, and the second DC power switch inside the sub-switch is open to cut-off to make the second power-saving power switch inside the sub-switch Open circuit to cut off the conduction, so that the DC power can be supplied to the main coil rotor (power supply main coil) inside the brushed DC motor through the main brush, and stop the DC power to be supplied to the vice The coil rotor (the secondary coil that stops supplying power) to drive the main coil rotor to rotate, or the power generating device and the brushed DC motor can also be mechanically separated for the main coil rotor to supply power to rotate and drive the load to work in a normal manner (DC The power is normally supplied to the motor). Using the concept of this motor to change the power supply, it can also achieve the normal power supply of the "replaceable energy-saving DC motor". can.         As described in the "replaceable energy-saving DC motor" circuit device described in claim 3, the replaceable energy-saving DC motor can also change the operation of the microprocessor to make the first DC power switch inside the main switch open circuit to cut off and conduct Make the first power-saving power switch inside the main switch to be closed for conduction, and make the second DC power switch inside the sub-switch to be open for disconnection, so that the second power-saving power switch inside the sub-switch is The closed circuit is used for conduction, so that the replacement energy-saving DC motor can use the DC power to supply power to the main coil rotor (power supply main coil) inside the brushed DC motor through the power-saving controller of the power-saving device and the main brush to simultaneously drive the main The coil rotor and the sub-coil rotor rotate, and the electromagnetic induction between the N-magnet and S-magnet inside the sub-coil rotor and the power generating device can generate electricity (sub-coil power generation). In this way, the power generating device and the brushed DC motor can be mechanically It is connected to rotate the secondary coil rotor to generate electricity, and drive the load to work in a power-saving manner (DC power-saving power-supply motor). The concept of power, it can reach the "replacement of energy-saving DC motor" saving power supply of the power supply function.
