[0002] The reluctance motor is a synchronous motor. The operating principle of the reluctance motor is that the magnetic flux always closes along the path with the minimum magnetic resistance. Therefore, when the iron core moves to the position of minimum magnetic resistance, its main axis must coincide with the axis of the magnetic field. In order to ensure the stable operation of the reluctance motor, the magnetic ring needs to be tested after production.

[0003] The existing magnetic ring detection device has a complex structure and is insufficient in performing fast and convenient detection operations, and its overall practicality needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a permanent magnet assisted synchronous reluctance motor magnetic ring detection device that can quickly and conveniently detect the magnetic force of the magnetic ring, with a compact and stable overall structure and strong practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A permanent magnet assisted synchronous reluctance motor magnetic ring detection device includes a support base, a clamping fixed base and a support frame fixedly connected to the upper surface of the support base, a detection base fixedly installed at one end of the support frame, a piston rod slidably installed at one end of the detection base, one end of the piston rod fixedly connected to a linkage plate, a permanent magnet steel fixedly connected to the outer surface of one side of the linkage plate, the interior of the detection base is filled with hydraulic oil, a pressure sensor is installed on the side surface of the detection base, the detection end of the pressure sensor is in the hydraulic oil, a pressure alarm is fixedly installed at one end of the support frame, the pressure alarm is electrically connected to the pressure sensor, and a clamping movable base is provided on one side of the clamping fixed base.

[0008] Furthermore, a slide rail is fixedly connected to the upper surface of the support base, and the clamping movable seat is slidably connected in the slide groove of the slide rail. A threaded hole is provided on the outer surface of the clamping movable seat, and a screw rod passes through the inside of the threaded hole. One end of the screw rod is rotatably connected to the side surface of the clamping fixed seat.

[0009] By adopting the above technical solution, the screw rod can be rotated to make the clamping movable seat slide in the slide groove of the slide rail, thereby effectively clamping the magnetic ring.

[0010] Furthermore, a rubber block is adhered to the adjacent side surfaces of the clamping fixed seat and the clamping movable seat.

[0011] By adopting the above technical solution, the overall insulation performance is ensured.

[0012] Furthermore, a digital display is provided above the pressure alarm, and the digital display is electrically connected to the pressure alarm.

[0016] Furthermore, a resistance adjuster, an ammeter, and a switch are fixedly mounted on the upper surface of the support base, and the switch, the resistance adjuster, the ammeter, and the terminal block are connected in series.

[0017] By adopting the above technical solution, the maintenance current can be effectively controlled and regulated.

[0018] In summary, the beneficial technical effects of the present invention are:

[0019] 1. The utility model can place the magnetic ring to be tested between the clamping fixed seat and the clamping movable seat, and then make the clamping movable seat close to the clamping fixed seat, thereby clamping and fixing the magnetic ring, and then energize the magnetic ring. At this time, one end of the magnetic ring generates magnetic force. Since permanent magnet steel is provided on one side of the clamping fixed seat, according to the principle of like poles repelling, the linkage plate is subjected to force, which in turn drives the piston rod to move, squeezing the hydraulic oil inside the detection seat, and the oil pressure of the hydraulic oil increases. At this time, the pressure sensor can detect the oil pressure and transmit the detected data to the inside of the pressure alarm. When the detected pressure value is not within the set range, the pressure alarm alarms, and the staff can quickly detect whether the magnetic force generated by the magnetic ring meets the standard. The device has a compact structure and is easy to operate.

[0020] 2. The utility model can use the ammeter to detect the current size of the input magnetic ring in real time, and use the resistance regulator to flexibly adjust the size of the transmission current, thereby flexibly and conveniently detecting the magnetic force size of the magnetic ring under different current sizes, and the detection operation is flexible and adjustable.

A digital display 18 is provided, and the digital display 18 is electrically connected to the pressure alarm 17, wherein the magnetic ring to be detected can be placed between the clamping fixed seat 7 and the clamping movable seat 9, and then the clamping movable seat 9 is made close to the clamping fixed seat 7, thereby clamping and fixing the magnetic ring, and then the magnetic ring is energized. At this time, a magnetic force is generated at one end of the magnetic ring. Since a permanent magnet steel 6 is provided on one side of the clamping fixed seat 7, according to the principle of like poles repelling each other, the linkage plate 5 is subjected to a force, thereby driving the piston rod 19 to move, squeezing the hydraulic oil inside the detection seat 3, and the oil pressure of the hydraulic oil increases. At this time, the pressure sensor 4 can detect the oil pressure and transmit the detected data to the inside of the pressure alarm 17. When the detected pressure value is not within the set range, the pressure alarm 17 alarms, and the staff can quickly detect whether the magnetic force generated by the magnetic ring meets the standard. The device has a compact structure and is easy to operate.

[0027] Referring to Figure 1, a slide rail 8 is fixedly connected to the upper surface of the support base 1, and the clamping movable seat 9 is slidably connected to the slide groove of the slide rail 8. A threaded hole is provided on the outer surface of the clamping movable seat 9, and a screw 11 passes through the inside of the threaded hole. One end of the screw 11 is rotatably connected to the side surface of the clamping fixed seat 7. When detecting the magnetic ring, the magnetic ring to be detected can be placed between the clamping fixed seat 7 and the clamping movable seat 9, and then the screw 11 is rotated. The rotation of the screw 11 drives the clamping movable seat 9 to slide in the slide groove of the slide rail 8, so that the magnetic ring to be detected can be clamped and fixed, ensuring that subsequent detection operations can be carried out effectively.

[0028] Referring to Figure 1, a terminal block 14 is fixedly installed on the upper surface of the support base 1, and the terminal block 14 is provided with two conductive clips 16, which are electrically connected to the terminal block 14.

At this time, the magnetic ring can be effectively energized, and one end of the magnetic ring generates magnetic force. Since a permanent magnet steel 6 is provided on one side of the clamping fixed seat 7, according to the principle of like poles repelling each other, the linkage plate 5 Under the action of force, the piston rod 19 is driven to move, squeezing the hydraulic oil inside the detection seat 3, and the oil pressure of the hydraulic oil increases. At this time, the pressure sensor 4 can detect the oil pressure and transmit the detected data to the inside of the pressure alarm 17.

During the entire detection process, the ammeter 13 can be used to detect the current of the input magnetic ring in real time, and the resistance regulator 12 can be used to flexibly adjust the size of the transmission current. The detection flexibility is high, and during the detection process, the digital display 18 can be used to view the pressure value in real time.
