[0024] Two assembly frames 105 are fixedly installed on the connection seat 102 and are respectively located on one side of the iron core shell 104. The connection seat 102 is fixedly connected to the parallel coil shell 101 through the two assembly frames 105. The user screws a screw through the assembly frame 105 to fix the connection seat 102 on the parallel coil shell 101. A parallel coil is arranged inside the parallel coil shell 101 and cooperates with the series coil on the magnetic field series coil 9 to connect the armature coil and the field coil in series, so that the characteristics of both an induced magnetic field and a magnetically excited magnetic field are generated during the working process.

[0025] Two assembly holes 7 are opened on the surface of the rear end cover 5. Assembly screws 11 extending into the inside of the outer shell part 3 are installed inside the two assembly holes 7. The installation of the assembly screws 11 improves the assembly stability of the rear end cover 5 and the outer shell part 3.

[0026] On one side of the rear end cover 5, four ignition coil terminals 12 arranged in a rectangle are fixedly installed. The installation of the ignition coil terminals 12 converts low-voltage direct current into a high-voltage power supply with a voltage that can reach tens of thousands of volts, providing sufficient ignition energy for the spark plugs. This conversion process relies on the ignition controller to accurately distribute high-voltage ignition signals according to the ignition requirements of each cylinder. During the operation of the DC motor, the spark plugs generate sparks by disrupting the ionization state of the air, thereby achieving the ignition of the air-fuel mixture. The ignition coils store and release energy at different frequencies according to the speed change of the DC motor to ensure the effective operation of the DC motor.

[0027] A gasket 6 is sleeved at the connection between the front end cover 1 and the clutch 4. Fixed holes 2 are provided at the four corners on one side of the front end cover 1. An installation hole 13 is provided in the middle of the rear end cover 5. The installation hole 13 is correspondingly arranged with the ejector rod 15.

The user uses screws to pass through the fixed holes 2 to install the DC motor at the place of use.

[0028] A number of heat dissipation holes 16 are provided on the surface of the clutch 4. The provision of the heat dissipation holes 16 increases the heat dissipation area of the clutch 4 itself and improves the heat dissipation performance of the DC motor.

[0029] The housing part 3 includes a first housing 31 and a second housing 32. One side of the first housing 31 is snap-connected to one side of the second housing 32. One end of the first housing 31 and one end of the second housing 32 are both snap-connected to the side facing the rear end cover 5. The other end of the first housing 31 and the other end of the second housing 32 are both snap-connected to the side facing the front end cover 1. The first housing 31 and the second housing 32 are made of stainless steel material, improving the compressive and corrosion resistance of the DC motor.

[0030] When the embodiment of the present application is in use: The user uses a screw to pass through the fixing hole 2 to install the DC motor at the place of use. The first housing 31 and the second housing 32 are made of stainless steel material, which improves the compressive and corrosion-resistant properties of the DC motor. The clutch 4 on the DC motor is mainly used to control the speed regulation, braking, starting, and reverse of the machine. The clutch 4 transmits the power and torque of the actuator from one side of the driving shaft to the other side of the driven shaft to achieve functions such as rapid braking, rapid start, forward and reverse rotation, braking, and speed regulation. The installation of the ignition coil terminal 12 converts low-voltage direct current into a high-voltage power supply, and the voltage can be as high as tens of thousands of volts, providing sufficient ignition energy for the spark plug. This conversion process depends on the ignition controller accurately distributing high-voltage ignition signals according to the ignition requirements of each cylinder. During the operation of the DC motor, the spark plug generates a spark by destroying the ionization state of the air, thereby achieving the ignition of the air-fuel mixture. The ignition coil stores and releases energy at different frequencies according to the speed change of the DC motor to ensure the effective operation of the DC motor. The gasket 6 is made of rubber material, and the laying of the gasket 6 increases the sealing performance between the front end cover 1 and the clutch 4. The silicone soft pad 14 is made of silicone material, and the silicone soft pad 14 fills the gap between the ejector rod 15 and the mounting hole 13, increasing the overall sealing performance of the DC motor.
