Description

Technical Field

[0001] The present invention relates to the field of motor technology, and in particular to a phase adjustment method and device for a dual-stator permanent magnet dynamic pressure gyro motor. Background Art

[0002] The dual-stator permanent magnet dynamic pressure gyro motor has the advantages of high speed, high efficiency, large momentum, and stable speed, making it increasingly widely used in high-precision gyroscopes in the fields of aerospace, shipbuilding, etc.

[0003] The dual-stator permanent magnet dynamic pressure gyro motor generally adopts a through-hole H-type dynamic pressure gas bearing structure. A magnet is fixedly installed at each end of the rotor, and each is equipped with a Dasson Fall type coreless stator. The magnet and stator are symmetrically distributed at both ends of the rotor ring. The current phase adjustment method is to first make zero position marks on the magnet and stator respectively. During assembly, the two magnets are first aligned at zero position, and then the two stator zero positions are aligned with the magnet zero position. Due to assembly errors, the two stators will be out of phase, resulting in reduced efficiency and increased temperature rise of the dual-stator permanent magnet dynamic pressure gyro motor. In severe cases, the dual-stator permanent magnet dynamic pressure gyro motor may not rotate normally, resulting in damage to the dynamic pressure gas bearing, which directly affects the life and reliability of the dual-stator permanent magnet dynamic pressure gyro motor and the gyroscope.

[0020] A method for adjusting the phase of a dual-stator permanent magnet dynamic pressure gyro motor comprises the following steps, and its flow chart is as follows: Figure 1 As shown: S1: The rotor 24 is rotatably mounted on the motor shaft, the first stator is mounted on one end of the motor shaft and fixedly locked with the motor shaft, and the second stator is mounted on the other end of the motor shaft and pre-locked with the motor shaft to form a motor assembly; Specifically, the first stator and the motor shaft can be fixed and locked by a first stator locking nut to ensure that the first stator does not rotate, and the second stator and the motor shaft can be pre-locked by a second stator locking nut, that is, the second stator locking nut is in a loose state, and the second stator can rotate slightly during phase adjustment.

[0021] S2: placing the assembled motor assembly on the mounting bracket, and pressing one end of the motor shaft where the first stator is mounted against the mounting bracket; Specifically, one end of the motor shaft where the first stator is mounted can be pressed against the mounting bracket by a fixing block, and the fixing block and the mounting bracket can be fixed by screws to prevent the motor shaft from rotating or jumping.

[0022] S3: energize the first stator to generate a magnetic field, which drives the rotor to rotate; S4: Detect the phases of the first stator and the second stator respectively and compare them. If the phases of the first stator and the second stator are inconsistent, proceed to step S5. If the phases of the first stator and the second stator are consistent, directly jump to step S6. Specifically, the first stator and the second stator may be connected to a dual-channel oscilloscope respectively to detect the phases of the first stator and the second stator.

[0023] The first stator, the second stator and the dual-channel oscilloscope are connected in the following manner: the A phase of the first stator is connected to the high end of the first channel 41 of the dual-channel oscilloscope, the B phase of the first stator is connected to the low end of the first channel of the dual-channel oscilloscope, the A phase of the second stator is connected to the high end of the second channel 42 of the dual-channel oscilloscope, and the B phase of the second stator is connected to the low end of the second channel of the dual-channel oscilloscope. The specific connection diagram of the dual-channel oscilloscope is shown in FIG. Figure 2 shown.

[0024] S5: installing an adjusting tool on the mounting bracket to drive the second stator to rotate until the phase of the second stator is consistent with the phase of the first stator; Specifically, the adjusting tool includes a connecting component and a micro-motion rotating component, wherein the connecting component is mounted on the mounting bracket and connected to the second stator, and the micro-motion rotating component is connected to the connecting component and drives the connecting component to drive the second stator to rotate.

[0025] S6: After fixing the second stator to the motor shaft, remove the motor assembly from the mounting bracket and lock the second stator to the motor shaft.

[0026] Specifically, the second stator and the motor shaft may be fixed by glue.

[0027] By adopting the above method, the first stator and the motor shaft are first fixed and locked, the second stator and the motor shaft are pre-locked, and then the phase of the first stator and the second stator is detected. If the phase of the first stator and the second stator is different, the phase of the second stator is adjusted to make the phase of the first stator consistent with that of the second stator, thereby ensuring the consistency of the phase of the dual stators in the actual operation of the dual-stator permanent magnet dynamic pressure gyro motor, avoiding the temperature drift problem of the gyroscope caused by the increased power consumption and temperature rise of the dual-stator permanent magnet dynamic pressure gyro motor, and improving the operating efficiency of the dual-stator permanent magnet dynamic pressure gyro motor, thereby ensuring the stable and reliable operation of the dual-stator permanent magnet dynamic pressure gyro motor and the gyroscope.

[0029] Furthermore, one end of the motor shaft on which the first stator is mounted is pressed against the mounting bracket in the V-shaped supporting groove through a fixing block 5 .

[0030] One end of the motor shaft mounted on the first stator is pressed tightly in the V-shaped support groove through a fixing block and a mounting bracket, so that the motor shaft can be kept stationary during the phase adjustment process, thereby keeping the first stator stationary.

[0031] The fixing block and the mounting bracket can be fixed by screws.

[0032] Optimally, the oscilloscope is a dual-channel oscilloscope, which can detect the phase of the first stator and the phase of the second stator at the same time, and is convenient for comparison and adjustment.

[0033] Furthermore, the connecting component is provided with two connecting rods 611 at one end and a polygonal hole 612 at the other end.

The fine-motion rotation shaft extends into the polygonal hole on the connecting component. The fine-motion rotation knob is installed on the fine-motion rotation shaft to drive the fine-motion rotation shaft to rotate.

[0034] When phase adjustment is required, just gently rotate the micro-motion rotary knob to drive the micro-motion rotary shaft to rotate. The rotation of the micro-motion rotary shaft drives the connection component to rotate. The rotation of the connection component then drives the second stator to rotate, facilitating the phase adjustment of the second stator.

[0035] The second stator is provided with two groups of connection holes, and the two connection rods can be inserted into any group of connection holes, so as to facilitate the connection between the connection component and the second stator and adjust the connection position.

[0036] Optimally, the polygonal hole is a regular hexagonal hole, and the micro-motion rotating shaft is a regular hexagonal structure, so as to prevent the micro-motion rotating shaft from slipping during the rotation process and affecting the rotation of the connecting component.
