[0002] A reluctance motor is an electric motor that operates on the principle of minimum reluctance. The core principle is that when the stator winding is connected to the current to generate a magnetic field, the magnetic field tends to pass through the path with the minimum magnetic resistance, thereby generating a magnetic pull on the rotor to drive the rotor to rotate to achieve energy conversion.

The ball screw 610 is a prior art, which is provided with an external thread groove on the surface, and the inner side of the sliding block 604 is provided with a ball, so that when the ball screw 610 rotates, the sliding block 604 moves forward and backward on the surface in a threaded manner.

The end of the shielding plate 602 away from the stator 8 is fixedly connected with the connecting seat 603, and when the connecting seat 603 is in contact and matched with the splicing block 608, the movement of the splicing block 608 drives the connecting seat 603 and the stator 8 to move on the inner side of the outer shell 1, thereby adjusting the gap with the rotor 7. The surface of the end cover 5 is provided with a positioning groove, the connecting seat 603 penetrates and is in contact with the inner wall of the positioning groove of the end cover 5, the two are in contact, so that when the end cover 5 is spliced with the outer shell 1, the connecting seat 603 penetrates the inner wall of the end cover 5, thereby positioning and splicing the end cover 5 with the outer shell 1, thereby avoiding the change of the angle of the end cover 5, which needs to be constantly adjusted. The arc surface of the rear end of the stator 8 is fixedly connected with a guide block 601, the inner side wall of the outer shell 1 is provided with a guide groove, and the guide block 601 is slidably connected to the inner wall of the guide groove of the outer shell 1. The movement of the guide block 601 can guide the movement of the stator 8, so that it can only move linearly forward and backward on the inner side of the outer shell 1.

[0057] Referring to Figure 1 and Figure 4The left side of the inner side wall of the outer shell 1 is provided with a Hall sensor 12, which is a prior art and functions to detect the air gap magnetic density. The right side of the inner side wall of the outer shell 1 is provided with a temperature sensor 10, which is a prior art and functions to monitor the winding and core temperature. The top end of the inner side wall of the outer shell 1 is provided with a torque sensor 11, which is a prior art and functions to detect the load. The electric control box 3 is electrically connected with the Hall sensor 12. The electric control box 3 is electrically connected with the temperature sensor 10. The electric control box 3 is electrically connected with the torque sensor 11. The torque sensor 11 first judges whether the whole is currently heavy load or light load, fast or slow rotation, so as to determine whether the magnetic gap is to be adjusted large or small. For example, when the heavy load is slowly rotated, the magnetic gap needs to be small to generate power. When the light load is quickly rotated, the magnetic gap needs to be large to save power. The Hall sensor 12 is responsible for "seeing" the actual size of the current magnetic gap by detecting the strength of the magnetic field, and telling the system how much the current state is away from the target. The temperature sensor 10 monitors the motor and will not overheat. If the temperature is too high, the adjustment range of the magnetic gap will be limited, such as preventing the magnetic gap from being adjusted too small to cause the core to overheat, or being adjusted too large to cause the winding current to overheat. The three data are summarized, and after the data is output, the digital-to-analog converter system in the electric control box 3 converts the calculated magnetic gap adjustment amount (such as whether to adjust large or small, and how much) into an electrical signal, which is directly sent to the servo motor 609 driving the ball screw 610. After receiving the signal, the servo motor 609 drives the ball screw 610 to rotate according to the direction (forward or reverse) of the signal. When the ball screw 610 rotates, the slider 604 above the ball screw 610 will translate along the screw. The slider 604 is connected to the magnetic gap adjusting mechanism of the motor. Therefore, when the slider 604 moves, the magnetic gap of the motor will become larger or smaller.

[0058] The magnetic gap adjustment amount calculation formula is:

[0059] Target magnetic gap g target Determined by load torque, speed and temperature:

[0060]

[0061] g0: reference magnetic gap under rated working condition (mechanical design value); T: real-time temperature sensor acquisition; T0: normal temperature reference, T max : maximum allowable temperature; n: real-time speed, n max : rated speed; M: real-time torque, M max : rated torque; k T ,k n ,k M : temperature, speed and torque correction coefficient, calibrated by experiment, range 0-1.

[0062] Working principle: when the motor starts, the electric control box 3 supplies power to the inside of the shell body 1 through the external circuit, the current is delivered to the stator winding 9 on the surface of the stator 8, so that the stator 8 generates a magnetic field. According to the principle of minimizing the magnetic field path reluctance, the magnetic field will drive the rotor 7 to start rotating. The positioning slot at the front end of the rotor 7 can be connected with the shaft coupling through the positioning pin, realizing the power output. The outer arc surface of the rotor 7 is in contact with the inner arc surface of the bearing 14, which provides support for the rotation of the rotor 7, effectively reducing the wear during rotation. At the same time, the annular groove at the center of the end cover 5 and the annular groove at the center of the connecting head 13 both play an auxiliary positioning role for the rotor 7, ensuring the stability of the rotor 7 during rotation.

[0063] When the motor is running, the intelligent adjustment of the magnetic gap is the core link, which is completed by the gap adjusting assembly 6 and various sensors. The torque sensor 11 on the inside of the shell body 1 detects the load condition and the motor speed, so as to determine whether the magnetic gap needs to be adjusted larger or smaller. For example, when the load is heavy and the speed is slow, adjusting the magnetic gap smaller can enhance the power; when the load is light and the speed is fast, adjusting the magnetic gap larger can save more electricity. The Hall sensor 12 is responsible for detecting the actual magnetic gap size, which realizes it by detecting the air gap magnetic density, and feeds back the current magnetic gap state to the system, so that the system knows the gap with the target magnetic gap. The temperature sensor 10 monitors the temperature of the winding and the core. If the temperature is too high, the adjustment range of the magnetic gap will be limited to prevent the core from overheating due to too small magnetic gap, or the winding current from being too large to cause heating due to too large magnetic gap, ensuring the safety of the adjustment process. After the data of the three sensors is collected in the electric control box 3, the digital-to-analog converter system in the electric control box 3 processes the data, converts the calculated magnetic gap adjustment amount, including adjusting larger, adjusting smaller and the adjustment range, into an electrical signal, and sends it to the servo motor 609 in the side wall of the connecting head 13. After receiving the signal, the servo motor 609 rotates the ball screw 610 according to the direction indicated by the signal. Since the sliding block 604 is screw-connected to the surface of the ball screw 610, and the sliding block 604 is slidingly connected in the sliding groove of the connecting head 13, when the ball screw 610 rotates, the sliding block 604 will translate along the ball screw 610, and at the same time, the sliding ring 605 fixedly connected thereto will move forward and backward on the outer arc surface of the connecting head 13.

[0064] When the sliding ring 605 moves, the four sets of hinged rods 606 hinged at the rear end will push the connecting block 607, which slides in the sliding groove on the front end surface of the end cover 5, thereby driving the splicing block 608 to move. The recess on the front end surface of the splicing block 608 is in contact with the round rod of the connecting seat 603, and the movement of the splicing block 608 will drive the connecting seat 603, the shielding plate 602 and the stator 8 to move together. The guide block 601 on the rear end arc surface of the stator 8 is slidingly connected in the guide groove on the inside of the shell body 1, which plays a guiding role in the movement of the stator 8, so that it can only move linearly forward and backward inside the shell body 1, finally realizing the precise adjustment of the magnetic gap between the stator 8 and the rotor 7, and ensuring that the motor is always in an efficient running state.

[0065] In addition, the outer wall of the shielding plate 602 is in contact with the surface of the rear end of the end cover 5, which can shield the through positioning groove opened on the surface of the end cover 5, and reduce the dust entering the motor. In the whole process, the components work cooperatively to realize the stable operation of the intelligent reluctance motor and the intelligent adjustment of the magnetic gap.
