伺服電動機,同服電動機有兩項技術(shù)值得注意，一是高密度電機，采用一種叫”大極電機”的設(shè)計思想，例如六極力槽電機，定子由力 人獨文的極構(gòu)成，在每個極上繞制集中線圈，然后再將九個極拼裝起來，形成九個的電機鐵芯，由于每個極是獨立繞制和整形，所以即使采用自動機繞，也能保持槽滿率高達(dá)90%，這類電機制造工藝好，空間利用和體積都達(dá)到了最小化，故稱為高密度電機。從運行原理上講，這類電機不屬于旋轉(zhuǎn)磁場電機，它在三相脈振磁場下工作，因此，它的適用性、設(shè)計方法和運行方式都有一定特殊性，所以這類電機不適合方波電流驅(qū)動。另一類是嵌入式磁鋼速率同服電動機，它可利用凸極效應(yīng)引起的交、直軸電感隨位置變化的特點，構(gòu)成真正意義上的無位置傳感器速率同服電動驅(qū)動系統(tǒng)。傳感器除了各類光電編碼器以外，磁編碼器值得關(guān)注，磁編碼器的體積和重量都比光電編碼器小幾十倍，溫度范圍更寬，幾乎不怕沖擊和振動。其工作原理非常簡單，它的定子是一顆內(nèi)嵌霍爾磁敏元件和DSP的芯片，體積可以小到MSOP-24封裝，它的轉(zhuǎn)子是一顆兩極磁鋼。它的分辨率10-12位，精度8-10位，這種磁編碼器已有供應(yīng)，作為空間應(yīng)用，為了滿足-35-80環(huán)境要求，幾乎難以采用傳統(tǒng)的光電編碼器，為此我們自行研制了磁編碼器，分辨率16位，精度12位，磁編碼器信號處理電路共存于驅(qū)動控制電路(FPGA) 中，形成傳感器與驅(qū)動控制電路一體化。

電流傳感器是同服控制必不可少的，小功率系統(tǒng)可以采用電陽采樣，一般可采用1 霍爾電流傳感器。兩種方法都要將模擬信號轉(zhuǎn)換成數(shù)字信號，然后參于數(shù)字同服控制。上述A/D轉(zhuǎn)換的輸出形式通常是串行數(shù)字脈沖或脈寬調(diào)制信號。同服單元 2003年美國1R公司推出單芯片速率同服控制系統(tǒng)，它內(nèi)部包括:電機矢量FOC控制器、電流PI調(diào)節(jié)器、速度Pl調(diào)節(jié)器、SVPWM調(diào)制器、傳感器接口、SPI和并行通信接口等。IR公司推出的單芯片速率同服控制系統(tǒng)的最重要特點是，允許用戶對上百種參數(shù)進行實時的和初始化給定，該技術(shù)在一片F(xiàn)PGA中實現(xiàn)了FOC控制器、電流P調(diào)節(jié)器、速度P調(diào)節(jié)器、位置PID調(diào)節(jié)器、速度前饋控制器、1R濾波器、SVPWM調(diào)制器、梯形速度軌跡生成器、位置指今處理器、監(jiān)控與保護環(huán)節(jié)、通訊模塊、寄存器堆等所有伺服控制模塊，并且在內(nèi)部集成了CPU，可以完成捷盤、顯示及外部通訊控制，為真正的數(shù)字可編程片上系統(tǒng)SOPC)。由于所有控制算法均用硬件實現(xiàn)，所以同服控制器可以達(dá)到相當(dāng)高的性能，其電流環(huán)與速度環(huán)采樣頻率均可達(dá)到20kHz，位置環(huán)采樣頻率可達(dá)10kHz以上，頻率指標(biāo)主要由芯片本身性能限制。通過上位機可以訪問所有內(nèi)部寄存器，能實現(xiàn)各種控制目的。所有參數(shù)可以進行在線修改，包括開關(guān)頻率、死區(qū)時間、調(diào)節(jié)器參數(shù)、濾波器參數(shù)等。適應(yīng)于PMSM、IM、BLDCM等不同電機的驅(qū)動控制，并兼容霍爾傳感器、增量式/絕對式碼盤、磁編碼器、旋轉(zhuǎn)變樂器等各類傳感器接口信號。可以接收脈沖指令、模擬指令以及數(shù)字指令等各種輸入信號，并可通過上位機或控制面板完成所有操作功能，具有控制器識別碼接口，易于實現(xiàn)多軸控制，這種單片控制器大大減少了系統(tǒng)體積，提高了抗干擾性，加上完善的保護措施，保證了系統(tǒng)運行的可靠性，

Servo control 28 amps 230 volts AC equipment network 2SK
Servo motor, the same service motor has two technologies worth noting, one is high-density motor, using a design idea called “large pole motor”, such as the six slot motor, the stator is composed of the pole of the force man alone, the concentrated coil is wound on each pole, and then the nine poles are assembled to form nine motor cores, because each pole is independently wound and reshaped. Therefore, even if the automatic winding, it can maintain the groove full rate of up to 90%, this kind of motor manufacturing process is good, space utilization and volume are minimized, so it is called high-density motor. From the operating principle, this type of motor does not belong to the rotating magnetic field motor, it works under the three-phase pulse vibration magnetic field, therefore, its applicability, design method and operation mode have certain particularity, so this type of motor is not suitable for square wave current drive. The other is the embedded magnetic steel speed synchronous motor, which can make use of the characteristics of the alternating and direct axis inductance caused by the salient pole effect with the change of position, to form a real position sensorless speed synchronous electric drive system. In addition to various types of photoelectric encoders, magnetic encoders deserve attention, the volume and weight of magnetic encoders are dozens of times smaller than the photoelectric encoder, the temperature range is wider, and it is almost not afraid of shock and vibration. Its working principle is very simple, its stator is an embedded Hall magnetic sensor and DSP chip, the volume can be as small as the MSOP-24 package, its rotor is a bipolar magnetic steel. Its resolution 10-12 bits, accuracy 8-10 bits, this magnetic encoder has been supplied, as a space application, in order to meet the requirements of -35-80 environment, it is almost difficult to use the traditional photoelectric encoder, so we have developed a magnetic encoder, resolution 16 bits, accuracy 12 bits, The signal processing circuit of the magnetic encoder coexists in the drive control circuit (FPGA), which forms the integration of the sensor and the drive control circuit.
The current sensor is essential to the same service control, and the small power system can use the positive sampling, generally can use the 1 hall current sensor. Both methods need to convert analog signals into digital signals, and then participate in digital co-service control. The output form of the above A/D conversion is usually a serial digital pulse or pulse-width modulated signal. In 2003, the United States 1R company launched a single-chip rate control system, which includes: motor vector FOC controller, current PI regulator, speed Pl regulator, SVPWM modulator, sensor interface, SPI and parallel communication interface. The most important feature of IR’s single-chip rate-to-service control system is that it allows users to perform real-time and initialization Settings for hundreds of parameters. The technology realizes all servo control modules such as FOC controller, current P regulator, speed P regulator, position PID regulator, speed feedforward controller, 1R filter, SVPWM modulator, ladder speed track generator, position indicator current processor, monitoring and protection link, communication module, register stack, etc., in one FPGA. And in the internal integration of the CPU, can complete the jet disk, display and external communication control, for the real digital programmable system on chip SOPC). Because all the control algorithms are implemented by hardware, the co-service controller can achieve quite high performance. The sampling frequency of the current loop and speed loop can reach 20kHz, and the sampling frequency of the position loop can reach more than 10kHz. The frequency index is mainly limited by the performance of the chip itself. Through the host computer can access all the internal registers, can achieve a variety of control purposes. All parameters can be modified online, including switching frequency, dead time, regulator parameters, filter parameters, etc. Suitable for PMSM, IM, BLDCM and other different motor drive control, and compatible with Hall sensor, incremental/absolute code disk, magnetic encoder, rotary instrument and other sensor interface signals. It can receive various input signals such as pulse instructions, analog instructions and digital instructions, and complete all operation functions through the upper computer or control panel, with controller identification code interface, easy to achieve multi-axis control, this monolithic controller greatly reduces the system volume, improves anti-interference, coupled with perfect protection measures to ensure the reliability of the system operation.
