[0002] Currently, most of the blade motors used in lawn mowers on the market are brushless DC motors. During actual use, lawn mowers may encounter various complex working conditions, such as the density and humidity of different grass types, and the undulations of the terrain, which puts higher requirements on the performance of the blade motors used in lawn mowers.

[0003] Brushless DC motors have many shortcomings and are unable to perform weak magnetic field control, resulting in limited performance under different working conditions. Specifically, they have large starting current, high noise, high vibration, low maximum speed, and relatively low efficiency, and cannot make good use of permanent magnet synchronous motors.

When the electric push rod 101 is started, the piston rod 102 and the disc 103 are cooperated to enable the heat sink 104 to move back and forth. At the same time, when the outer ring gear 107 engages with the inner ring gear 108, the rotating shaft 641 can drive the heat sink 104 to rotate, so that the heat dissipation holes on the heat sink 104 are not easy to accumulate dust. An impeller 109 is fixedly installed on the outer side of the rear end of the rotating shaft 641, so that the external airflow flows from the front end to the rear end of the casing 1, thereby achieving a better heat dissipation effect.

[0029] Working principle: When the stator winding 611 is connected to three-phase alternating current with an alternating change pattern, the electrical energy is converted into magnetic field energy. The wire on each stator winding 611 can serve as a loop for any other two input wires. Each group of stator components 61 can form a separate magnetic field. The three groups of stator components 61 alternately generate magnetic fields, and finally form a rotating air gap magnetic field that can circulate. There is an air gap between the stator component 61 and the rotor component 64. When working, the two jointly establish an air gap magnetic field. The permanent magnet 643 of the rotor component 64 itself generates a magnetic field, which interacts with the magnetic field generated by the stator component 61. The rotor component 64 rotates and generates a rotational force. The use of a shunt magnetic conductive structure can eliminate the cogging torque. When the motor body is running, the rotor component 64 rotates synchronously with the rotation of the stator component 61, and finally the shaft 641 rotates.

[0030] Furthermore, the oil inlet end 72 can be used to input lubricating oil into the oil storage box 71, and the one-way valve 75 on the short tube 73 and the long tube 74 can be opened to input the lubricating oil into the outer side of the bearing member 63 in the bearing sleeve 62 for lubrication. The bottom end of the bearing sleeve 62 is fixedly installed with an oil outlet pipe 76, which is also provided with a one-way valve 75. The bottom end of the oil outlet pipe 76 is clamped with a collecting tank 77 for collecting waste oil. When the servo motor 82 is started, the rotating rod 83 is rotated, thereby driving the thin plate 84 to rotate to stir the waste oil, and at the same time driving the support rod 85 and the sensor block 86 to rotate, so as to control the intermittent opening and closing of the sensor 87. When the waste oil gradually increases and the viscosity increases, the initial given speed of the rotating rod 83 slows down. By obtaining the change in the opening and closing interval time of the sensor 87 and converting it into an electrical signal, the worker The operator can add new lubricating oil and dispose of waste oil in time. When the rotating shaft 641 rotates, the annular block 91 is driven to rotate, and the short column 92 and the sphere 93 are driven to rotate synchronously, so that the sphere 93 can hit the shrapnel 94, so that the shrapnel 94 is intermittently deformed, thereby stirring the lubricating oil in the bearing sleeve 62 to avoid sticking. When the electric push rod 101 is started, the piston rod 102 and the disc 103 are cooperated to make the heat sink 104 move back and forth. At the same time, when the outer ring gear 107 engages the inner ring gear 108, the rotating shaft 641 can drive the heat sink 104 to rotate, so that the heat dissipation holes on the heat sink 104 are not easy to accumulate dust. In addition, the rotating shaft 641 drives the impeller 109 to rotate, so that the external airflow flows from the front end to the rear end of the casing 1, thereby making the heat dissipation effect better.
