[0001] The utility model belongs to the technical field of three-phase asynchronous motors, in particular to a super-high efficiency three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor. Since the rotor and the stator rotating magnetic field rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque, ultimately achieving energy conversion.

[0003] When the existing three-phase asynchronous motor is used, due to factors such as high-speed rotation, the internal temperature of the motor will increase, affecting the efficiency of the motor output; and when installing the motor, after the motor is installed in the specified position, the output angle of the motor may be adjusted as needed, but after the motor is installed and fixed, the output angle cannot be directly adjusted.

[0027] Reference Figure 1-7 Now, an ultra-high efficiency three-phase asynchronous motor provided by an embodiment of the utility model is described. An ultra-high efficiency three-phase asynchronous motor comprises a housing 1 and a bottom plate 4 movably mounted at the bottom of the housing 1, a stator assembly 101 is mounted inside the housing 1, a rotor assembly 102 is movably mounted inside the stator assembly 101, an output shaft 103 is mounted inside the rotor assembly 102, a cooling mechanism is mounted inside the housing 1, a support plate 3 is fixedly connected to the bottom of the housing 1, a movable block 401 is fixedly connected between the support plate 3 and the bottom plate 4, and an adjustment mechanism is arranged between the bottom plate 4 and the support plate 3.

[0028] When in use, the utility model is fixed at a specified position through the base plate 4. When the angle of the utility model needs to be adjusted, the end of the support plate 3 away from the movable block 401 is lifted up through the adjustment mechanism, and the support plate 3 can drive the angle of the utility model; the rotor assembly 102 is driven to rotate through the stator assembly 101. When the rotor assembly 102 rotates, the temperature inside the utility model will increase, affecting the output efficiency of the utility model. At this time, the cooling mechanism can be driven by the output shaft 103 to cool the inside of the shell 1.

[0029] The cooling mechanism includes a fan 2, an air inlet 201 and an exhaust hole 202. The fan 2 is installed on the outer wall of the output shaft 103. A plurality of air inlet holes 201 are arranged in a ring shape at one end of the shell 1 close to the output shaft 103, and a plurality of exhaust holes 202 are arranged in a ring shape at one end of the shell 1 away from the air inlet holes 201. When the output shaft 103 rotates, the fan 2 is driven to rotate, and the outside air is sucked into the inside of the shell 1 through the air inlet holes 201 through the fan 2, and the hot air inside the shell 1 is blown out from the exhaust holes 202 at the same time, so that automatic cooling can be achieved during use, thereby improving the output efficiency of the utility model.

[0030] The adjustment mechanism includes a first mounting block 5, a second mounting block 501, a push plate 502, a slider 503, a connecting rod 504 and a moving groove 505. The top of the bottom plate 4 is fixedly connected with the first mounting block 5, the bottom of the support plate 3 is fixedly connected with the second mounting block 501, the push plate 502 is movably installed between the first mounting block 5 and the second mounting block 501, the slider 503 is slidably installed inside the first mounting block 5, the connecting rod 504 is movably installed between the push plate 502 and the slider 503, the first mounting block 5 is provided with a moving groove 505 for the slider 503 to slide, and the first mounting block 5 is provided with a driving component for driving the slider 503 to slide. When the angle of the utility model needs to be adjusted, the slider 503 is controlled to slide in the first mounting block 5 by the driving component, and the slider 503 drives the connecting rod 504 to move. At this time, the cooperation of the connecting rod 504 and the push plate 502 drives one end of the second mounting block 501 to tilt up, so as to achieve the adjustment of the angle of the utility model.

[0031] The driving assembly includes a movable hole 6, a screw rod 601, a driving shaft 602, a gear 603, a turning handle 604, an inner cavity 605 and a tooth groove 606. A movable hole 6 is opened inside the first mounting block 5. The screw rod 601 is movably installed inside the movable hole 6. The slider 503 is threadedly installed on the screw rod 601. The driving shaft 602 is fixedly connected to one end of the screw rod 601. The gear 603 is arranged at the end of the driving shaft 602 away from the screw rod 601. The turning handle 604 is installed on the driving shaft 602. The inner cavity 605 is opened inside the turning handle 604. The tooth groove 606 is opened inside the turning handle 604 and is located at the front end of the inner cavity 605. The gear 603 and the tooth groove 606 match each other. The diameter of the inner cavity 605 is larger than the diameter of the gear 603. When in use, pull the handle 604 outward to make the gear 603 stuck in the tooth groove 606, and at the same time the cylinder 8 disengages from the mounting hole 7, and then rotate the handle 604 to drive the screw rod 601 to rotate through the drive shaft 602, and the slider 503 can be driven to move through the screw rod 601, so that the adjustment component is controlled by rotating the handle 604.

[0032] The outer wall of the bottom plate 4 is provided with a mounting hole 7, and one end of the turning handle 604 is provided with a cylinder 8 corresponding to the mounting hole 7. When the utility model is adjusted to a suitable angle, the turning handle 604 is pushed inward to disengage the gear 603 from the tooth groove 606, and the turning handle 604 can rotate freely. When the cylinder 8 corresponds to the mounting hole 7, the turning handle 604 is installed inside the mounting hole 7 through the cylinder 8, which can prevent the turning handle 604 from being touched during use, causing the angle of the utility model to be offset.

[0033] The outer wall of the bottom plate 4 is fixedly connected with four rectangularly distributed fixing blocks 402 , and fixing bolts are installed inside the fixing blocks 402 . When in use, the bottom plate 4 can be used to fix the utility model at a designated position.

[0034] Working principle: When in use, the utility model is fixed at a specified position by the fixing block 402. When the angle of the utility model needs to be adjusted, the screw rod 601 is controlled to rotate by rotating the turning handle 604, and the screw rod 601 drives the slider 503 to move in parallel.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
