그러나 도 1에서 보는 종래의 집중권(권선을 한 개의 티스에 감거나 삽입하는 방법)에 의한 수소차 공기압축기용 Brushless 모터는 고속회전의 경우 발열이 심하게 발생하여 효율적인 모터 구동이 어려운 단점이 있었다. 그리고 도 2에서 보는 분포권(권선을 최소 2개 이상의 티스에 걸쳐서 감거나 삽입하는 방법)에 의한 일반 Brushless 모터는 수소차 공기압축기용 Brushless 모터에 적용하기에는 회전수와 토크 및 크기 제원 및 티스수, 권선의 개수 등의 최적설계가 이루어지지 않아 사용되지 못한 문제점이 있었다.However, the brushless motor for a hydrogen air compressor using a conventional concentrated winding (a method of winding or inserting a winding into one tooth) shown in Figure 1 had the disadvantage of generating severe heat at high speeds, making it difficult to drive the motor efficiently. In addition, the general brushless motor using the distribution winding (a method of winding or inserting the winding over at least two teeth) shown in Figure 2 cannot be applied to a brushless motor for a hydrogen air compressor due to the rotation speed, torque, size specifications, number of teeth, and winding. There was a problem that it could not be used because optimal design, such as the number of devices, was not achieved.
종래에는 슬롯수 6의 경우Conventionally, in the case of 6 slots,
제조 방법으로서 분할코어 → 집중권 권선 → 6 슬롯 코어 어레이 → 용접의 과정을 거쳐서 제조되었다.As a manufacturing method, it was manufactured through the following process: split core → concentrated winding → 6 slot core array → welding.
그러나, 모터의 권선 방법을 집중권으로 하여 모터 스테이터 코어에 코일을 감아서 조립하게 되는 데 공기압축기의 최대 출력으로 운전시 코일의 온도가 설계 요구치를 초과하여 품질 문제가 발생할 수 있는 가능성이 커진다. 이에 모터 냉각 공기홀을 증대하여 냉각을 추가했으나 효율이 떨어지고 설계 요구치를 불만족한 단점이 있었다.However, since the motor is assembled by winding a coil around the stator core using a concentrated winding method, the temperature of the coil exceeds the design requirement when operating at the maximum output of the air compressor, increasing the possibility that quality problems may occur. Accordingly, cooling was added by increasing the motor cooling air hole, but it had the disadvantage of being less efficient and not meeting the design requirements.
따라서 본 발명은 상기와 같은 문제점을 해결하고자 안출된 것으로, 고속회전이 가능하며, 토크가 크면서도 발열이 적어 효율적인 구동이 가능한 NdFeB 재질의 자석이 설치되는 수소차 공기압축기용 Brushless 모터 및 제조방법을 제공하고자 하는 것이다. 또한 슬롯수 증가에 의해 효율 증대 및 온도 저감이 되는 수소차 공기압축기용 Brushless 모터 제조 방법을 제공하고자 하는 것이다.Therefore, the present invention was developed to solve the above problems, and provides a brushless motor and manufacturing method for a hydrogen air compressor equipped with a magnet made of NdFeB that is capable of high-speed rotation, has high torque, and generates little heat, enabling efficient operation. This is what we want to provide. In addition, the aim is to provide a method of manufacturing a brushless motor for a hydrogen air compressor that increases efficiency and reduces temperature by increasing the number of slots.
본발명은 수소차 공기압축기용 Brushless 모터 제조 방법 에 관한 것으로, 모터의 슬롯수가 12 이상이며, 분포권 권선으로 제조되는 것을 특징으로 한다.The present invention relates to a method of manufacturing a brushless motor for a hydrogen air compressor, and is characterized in that the motor has 12 or more slots and is manufactured with distributed windings.
따라서 본 발명은 고속회전이 가능하며, 토크가 크면서도 발열이 적어 효율적이며, NdFeB 재질의 자석 및 SUS 재질(스테인레스 스틸 재질)의 슬리브 사용에 따른 제작단가가 저렴한 현저한 효과가 있다.또한 슬롯수 증가에 의해 효율 증대 및 온도 저감의 현저한 효과가 있다.Therefore, the present invention is capable of high-speed rotation, is efficient due to large torque and low heat generation, and has the remarkable effect of low production cost due to the use of NdFeB magnets and SUS (stainless steel) sleeves. In addition, the number of slots is increased. There is a significant effect of increasing efficiency and reducing temperature.

본발명 모터의 극수는 2극이며, 티스수는 10 ~ 14 개이며, 최적의 티스수는 12개 이다. 그리고 스테이터 코어의 지름 80 ~ 130 mm, 스테이터 코어의 길이는 40 ~ 80 mm 이다. The number of poles of the motor of the present invention is 2 poles, the number of teeth is 10 to 14, and the optimal number of teeth is 12. And the diameter of the stator core is 80 to 130 mm, and the length of the stator core is 40 to 80 mm.
가령 본 발명의 분포권 모터를 사용하는 25kW 공기압축기 경우, 셀온도 24.3(℃) 냉각수 온도(℃) 70, 대기압(kPa) 102.8, 입력전압(V) 520, 습도(%) 40.7의 환경에서 회전속도 10,8000rpm에서 30분간 최대출력에서 작동하여, 유량(kg/hr) 641, 출력(kw) 23.5일 경우, 온도 측정 결과는 인버터온도(℃) 53, 출구온도(℃) 133.5, 출구압력 (kPa) 216, 냉각수 온도(℃)70가 되며, 모터온도는 156.1(℃)에서 포화온도가 된다.For example, in the case of a 25 kW air compressor using the distribution motor of the present invention, the rotation speed is in an environment of cell temperature 24.3 (℃), coolant temperature (℃) 70, atmospheric pressure (kPa) 102.8, input voltage (V) 520, and humidity (%) 40.7. When operating at maximum output at 10,8000 rpm for 30 minutes, flow rate (kg/hr) 641, output (kw) 23.5, temperature measurement results are inverter temperature (℃) 53, outlet temperature (℃) 133.5, outlet pressure (kPa) ) 216, the coolant temperature (℃) becomes 70, and the motor temperature reaches saturation temperature at 156.1 (℃).
그러므로 본 발명의 분포권에 의한 모터의 발열온도가 180°C 이내 이므로, Therefore, since the heat generation temperature of the motor by the distribution range of the present invention is within 180°C,
2극의 자석은 종래의 약 400°C 까지 견디는 값비싼 SmCo 재질 대신 NdFeB 재질의 사용가능하며, 슬리브는 종래의 값비싼 인코넬 재질 대신 저가의 SUS 재질(스테인레스 스틸 재질)로 제작이 가능해진다.The two-pole magnet can be made of NdFeB material instead of the conventional expensive SmCo material that can withstand up to about 400°C, and the sleeve can be made of inexpensive SUS material (stainless steel material) instead of the conventional expensive Inconel material.

Specifically, when described by winding diagram, it is a BLDC Type based on 2Pole 6Slot 2Pitch 3 phases, and 2 fatigue windings of coils for each phase are performed to collect the final ground at 1 location, and each phase is concentrated and shown on a 3-phase basis. Coil forming: This is a core insert method after forming the wire coil in the same manner as the distribution winding. Based on U phase: One coil forming part is inserted into the 2nd and 3rd segments, and one additional coil forming part is inserted into the 5th and 6th segments, and finally gathered into the phase and ground.
