Abstract: The present invention relates to a novel replaceable motor energy-saving circuit device capable of generating power, supplying power with limited current, and switching power supply, which is to configure a power generation device, a power-saving device and a microcontroller outside a brush DC motor to together compose a replaceable energy-saving DC motor. The replaceable energy-saving DC motor is configured with an N-magnet, a S-magnet, a main coil rotor and a main electric brush inside a brush DC motor. The interior of the power generation device is configured with an N-magnet, a S-magnet, a secondary coil rotor and a secondary electric brush. The interior of the power-saving device is configured with a rectifying boost circuit, an IV conversion circuit, a voltage differentiator, a voltage control and current-limiting circuit, and a power connection circuit. The interior of the microcontroller is configured with a microprocessor and a switch. The replaceable energy-saving DC motor utilizes a DC power to drive the main coil rotor for rotation by the main electric brush and to activate a load work (supplying power to the main coil). The replaceable energy-saving DC motor further utilizes the main coil rotor to drive the secondary coil rotor inside the power generation device for rotation and generating power (secondary coil power generation). The generated power may supply the power in coordination through the secondary electric brush inside the power generation device and the power-saving device (supplying power by power generation), so the DC power may save the power supply (supplying power with reduced current). The microcontroller may switch the operation to using the main electric brush and the secondary electric brush to enable the main coil rotor and the secondary coil rotor to be supplied with power for rotation and also activate the load work (supplying power to the main coil and supplying power to the secondary coil). Or, the microcontroller may switch the operation to only using the main electric brush to enable the main coil rotor to be supplied with power for rotation to activate the load work (supplying power to the main coil and stop supplying power to the secondary coil). Moreover, the main coil rotor and the secondary coil rotor may be mechanically connected as a secondary coil rotor to rotate for power generation or as a main coil rotor and a secondary coil rotor to be supplied with power for rotation. The main coil rotor and the secondary coil rotor may also be mechanically detached as a main coil rotor to be supplied with power for rotation or as a replacement of secondary coil rotor (replaceable power generation device). Thus, in the present invention, the replaceable energy-saving DC motor composed of a brush DC motor and a power generation device, a power-saving device and a microcontroller may enable the power-saving device for current limiting and saving the power supply of DC power to the brush DC motor; enabling the microcontroller to switch and increase the power supply of DC power to the brush DC motor; or, enabling the microcontroller to switch and supply the normal power from DC power to the brush DC motor. With such a novel motor power generation and power supply, current-limiting power supply and switching motor power supply concept, the present invention may achieve the purposes of multiple power supply functions and energy saving that the brush DC motor may be supplied with power in a power-saving manner, or increase the power supply or normally supply the power.
