AKM12C-ANCNR-00 三相永磁同步電機(jī)

AKM12C-ANCNR-00稱為三相永磁同步電機(jī)，其核心特性在于其轉(zhuǎn)子勵磁磁場由永磁體提供。這種電機(jī)的運(yùn)行原理主要是通過控制三相電樞電流，使定子合成電流矢量和轉(zhuǎn)子勵磁磁場正交，從而產(chǎn)生電磁轉(zhuǎn)矩。由于只需要控制電樞電流就可以控制轉(zhuǎn)矩，因此同步電機(jī)的控制相對簡單。

同步伺服電機(jī)主要由定子、轉(zhuǎn)子和檢測元件三部分組成。定子齒槽里面有多相對稱繞構(gòu)成的定子，與普通電機(jī)的區(qū)別在于其外圓大多數(shù)是多邊形的，沒有設(shè)計(jì)外殼，這樣不會使熱量積聚，解決了因熱量聚集所導(dǎo)致的機(jī)床設(shè)備控制精度下降的問題。而永磁體則緊貼導(dǎo)磁軛，轉(zhuǎn)軸外側(cè)嵌套著磁軛，這種設(shè)計(jì)直接節(jié)省了材料，并避免了直流電機(jī)中換向器和電刷的損耗。檢測元件即編碼器，與轉(zhuǎn)子同處于一根互相連接的軸上，實(shí)現(xiàn)電機(jī)的閉環(huán)控制及轉(zhuǎn)速等反饋調(diào)節(jié)。

AKM12C-ANCNR-00在諸多方面表現(xiàn)出色。首先，由于其控制相對簡單、易維護(hù)且損耗小，因此得到了廣泛應(yīng)用。其次，由于電樞電流過大可能引起永磁體去磁且弱磁控制難，同步伺服電機(jī)并不適于大轉(zhuǎn)矩、大功率運(yùn)行，但其在較小容量的伺服系統(tǒng)中仍具有顯著優(yōu)勢。此外，交流伺服電機(jī)本身具有脈沖輸出功能，能與驅(qū)動控制單元形成閉環(huán)，從而提高了對電機(jī)的控制精度。

在實(shí)際應(yīng)用中，AKM12C-ANCNR-00在力矩、運(yùn)行控制、速度響應(yīng)、穩(wěn)定性等方面通常優(yōu)于步進(jìn)電機(jī)。同時，由于步進(jìn)電機(jī)本身沒有脈沖輸出功能，需要外額增加傳感器才可構(gòu)成閉環(huán)系統(tǒng)，而同步伺服電機(jī)則無需此額外步驟。

總的來說，AKM12C-ANCNR-00因其優(yōu)良的性能和廣泛的應(yīng)用領(lǐng)域而備受關(guān)注。在實(shí)際應(yīng)用中，需根據(jù)具體需求和場景選擇合適的同步伺服電機(jī)型號和規(guī)格，以確保其最佳性能和穩(wěn)定性。

AKM12C-ANCNR-00 三相永磁同步電機(jī)

AKM12C-ANCNR-00 is called a three-phase permanent magnet synchronous motor, its core feature is that its rotor excitation field is provided by a permanent magnet. The operation principle of this kind of motor is mainly by controlling the three-phase armature current, so that the stator synthesis current vector and the rotor excitation field are orthogonal, so as to produce electromagnetic torque. Because the torque can be controlled only by controlling the armature current, the control of synchronous motors is relatively simple.

Synchronous servo motor is mainly composed of stator, rotor and detection components. The stator groove has a polyphase symmetrical winding stator, and the difference with the ordinary motor is that the outer circle is mostly polygon, there is no design shell, so that the heat will not accumulate, to solve the problem of the machine tool equipment control accuracy decline caused by heat accumulation. The permanent magnet is close to the magnetic yoke, and the magnetic yoke is nested outside the rotating shaft, which directly saves the material and avoids the loss of the commutator and brush in the DC motor. The detecting element, the encoder, is located on an interconnected shaft with the rotor to realize closed-loop control of the motor and feedback adjustment of the speed.

The AKM12C-ANCNR-00 is excellent in many ways. First, it is widely used because of its relatively simple control, easy maintenance and low loss. Second, because the armature current is too large may cause permanent magnet demagnetization and weak magnetic control is difficult, synchronous servo motor is not suitable for large torque, high power operation, but it still has significant advantages in smaller capacity servo system. In addition, the AC servo motor itself has a pulse output function, which can form a closed loop with the drive control unit, thus improving the control accuracy of the motor.

In practical applications, AKM12C-ANCNR-00 is generally superior to stepper motors in terms of torque, operation control, speed response, stability, etc. At the same time, because the stepper motor itself does not have a pulse output function, an external sensor is required to constitute a closed-loop system, while the synchronous servo motor does not need this additional step.

Overall, the AKM12C-ANCNR-00 has attracted much attention for its excellent performance and wide range of applications. In practical applications, appropriate synchronous servo motor models and specifications should be selected according to specific needs and scenarios to ensure the best performance and stability.
