Description

Technical Field

[0001] The utility model relates to the technical field of BLDC motor control, in particular to a sensorless BLDC motor controller. Background Art

[0002] A BLDC (Brushless Direct Current) motor, primarily consisting of a motor and a BLDC motor driver, is a typical mechatronic product. A brushless motor is a motor without brushes and a commutator (or slip ring), also known as a commutatorless motor. Since its creation, brushless DC motors have found widespread application in industrial production. Their compact size, light weight, high efficiency, low noise, large capacity, and high reliability make them a promising alternative to traditional DC motors and the mainstream of motor drive systems.

[0003] Existing BLDC motor controllers are generally installed in a protective cover when in use to protect them. However, the controller generates heat during operation. If the heat is not dissipated in time, it will cause damage to the controller. When the controller needs to be repaired, it is troublesome to remove the protective cover. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides a sensorless BLDC motor controller.

[0005] The utility model is implemented by the following technical solution: a non-sensing BLDC motor controller, comprising a rotating mechanism, the top of the rotating mechanism is connected to a clamping mechanism, and the top of the clamping connection is fixedly connected to an air cooling mechanism;

[0006] The rotating mechanism includes a mounting plate, the interior of the mounting plate is fixedly connected to a fixing rod, the surface of the fixing rod is slidably connected to a slider, the right side of the slider is fixedly connected to a connecting plate, the right side of the connecting plate is fixedly connected to a rack clamping rod, the top of the mounting plate is rotatably connected to a first gear, the top of the first gear is fixedly connected to a connecting column, the top of the connecting column is fixedly connected to a second gear, fixing grooves are provided at the front and rear ends of the inner wall of the mounting plate, and a mounting groove is provided at the top of the mounting plate.

[0007] With the above technical solution, the outer gear of the second gear (one of three) drives the inner two gears, which in turn drive the first gear under the connecting column. This then meshes the first gear with the rack lever, causing one side of the rack lever to slide out of the fixed groove on the inner wall of the mounting plate, allowing the mounting box to be removed from the mounting groove. The mounting box can then be easily opened, providing direct access to the components inside the controller. This saves time and effort, improves maintenance and repair efficiency, facilitates cleaning and maintenance, and extends the life of the controller.

[0008] As a further improvement of the above solution, the clamping mechanism includes a mounting box, a controller body is provided inside the mounting box, and clamping slots are provided at the front and rear ends of the mounting box.

[0009] As a further improvement of the above solution, the air cooling mechanism includes a mounting seat, the top of the mounting seat is fixedly connected to a sleeve, the inside of the sleeve is fixedly connected to a fixing plate, the left side of the fixing plate is fixedly connected to a motor, and the output end of the motor is rotatably connected to a fan.

[0010] Through the above technical solution, the motor is started and the fan inside the sleeve on the mounting base rotates, which can effectively reduce the temperature of the controller, improve its reliability, slow down the aging of electronic components, and extend its service life. The fan is a component that is relatively easy to maintain. If the fan fails, it can be replaced in time without affecting the normal operation of the controller.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model provides a rack clamping rod to rotate the second gear, which has three gears. The outer gear drives the two inner gears, which in turn drive the first gear under the connecting column. The first gear then engages with the rack clamping rod, causing one side of the rack clamping rod to slide out of the fixing groove on the inner wall of the mounting plate, allowing the mounting box to be removed from the mounting groove. The mounting box can be easily opened, allowing direct access to the internal components of the controller. This saves time and energy, improves the efficiency of maintenance and repair, facilitates cleaning and maintenance, and extends the service life of the controller.

[0013] The utility model sets a fan, starts the motor, and rotates the fan inside the sleeve on the mounting base, which can effectively reduce the temperature of the controller, improve its reliability, slow down the aging speed of electronic components, and extend their service life. The fan is a component that is relatively easy to maintain. If the fan fails, it can be replaced in time without affecting the normal operation of the controller. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the mounting plate 101 is provided with a mounting slot 110. When the controller needs to be disassembled and repaired, the second gear 108 (of which there are three) is rotated. The outer gear drives the two inner gears, which in turn drive the first gear 106 under the connecting column 107. The first gear 106 then engages with the rack bar 105, causing one side of the rack bar 105 to slide out of the fixing slot 109 on the inner wall of the mounting plate 101, allowing the mounting box 201 to be removed from the mounting slot 110. The mounting box 201 can then be easily opened, allowing direct access to the internal components of the controller. This saves time and effort, improves the efficiency of maintenance and repair, facilitates cleaning and maintenance, and extends the life of the controller.

[0026] A groove is formed inside the mounting plate 101 , and two rack clamping rods 105 are provided.

[0027] The rack clamping rod 105 is engaged with the first gear 106 , and there are three second gears 108 . The rack clamping rod 105 is slidably connected to the fixing groove 109 .

[0028] The clamping mechanism 2 includes a mounting box 201 , a controller body 202 is provided inside the mounting box 201 , and clamping slots 203 are provided at the front and rear ends of the mounting box 201 .

The outer gear drives the two inner gears, thereby driving the first gear 106 under the connecting column 107, and then the first gear 106 is engaged with the rack clamp 105, so that one side of the rack clamp 105 slides out of the fixed slot 109 on the inner wall of the mounting plate 101, so that the mounting box 201 is removed from the mounting slot 110. The mounting box 201 can be easily opened to directly access the components inside the controller. This can save time and energy, improve the efficiency of maintenance and repair, facilitate cleaning and maintenance, and extend the service life of the controller.
