伺服电动机,同服电动机有两项技术值得注意，一是高密度电机，采用一种叫”大极电机”的设计思想，例如六极力槽电机，定子由力 人独文的极构成，在每个极上绕制集中线圈，然后再将九个极拼装起来，形成九个的电机铁芯，由于每个极是独立绕制和整形，所以即使采用自动机绕，也能保持槽满率高达90%，这类电机制造工艺好，空间利用和体积都达到了最小化，故称为高密度电机。从运行原理上讲，这类电机不属于旋转磁场电机，它在三相脉振磁场下工作，因此，它的适用性、设计方法和运行方式都有一定特殊性，所以这类电机不适合方波电流驱动。另一类是嵌入式磁钢速率同服电动机，它可利用凸极效应引起的交、直轴电感随位置变化的特点，构成真正意义上的无位置传感器速率同服电动驱动系统。传感器除了各类光电编码器以外，磁编码器值得关注，磁编码器的体积和重量都比光电编码器小几十倍，温度范围更宽，几乎不怕冲击和振动。其工作原理非常简单，它的定子是一颗内嵌霍尔磁敏元件和DSP的芯片，体积可以小到MSOP-24封装，它的转子是一颗两极磁钢。它的分辨率10-12位，精度8-10位，这种磁编码器已有供应，作为空间应用，为了满足-35-80环境要求，几乎难以采用传统的光电编码器，为此我们自行研制了磁编码器，分辨率16位，精度12位，磁编码器信号处理电路共存于驱动控制电路(FPGA) 中，形成传感器与驱动控制电路一体化。

电流传感器是同服控制必不可少的，小功率系统可以采用电阳采样，一般可采用1 霍尔电流传感器。两种方法都要将模拟信号转换成数字信号，然后参于数字同服控制。上述A/D转换的输出形式通常是串行数字脉冲或脉宽调制信号。同服单元 2003年美国1R公司推出单芯片速率同服控制系统，它内部包括:电机矢量FOC控制器、电流PI调节器、速度Pl调节器、SVPWM调制器、传感器接口、SPI和并行通信接口等。IR公司推出的单芯片速率同服控制系统的最重要特点是，允许用户对上百种参数进行实时的和初始化给定，该技术在一片FPGA中实现了FOC控制器、电流P调节器、速度P调节器、位置PID调节器、速度前馈控制器、1R滤波器、SVPWM调制器、梯形速度轨迹生成器、位置指今处理器、监控与保护环节、通讯模块、寄存器堆等所有伺服控制模块，并且在内部集成了CPU，可以完成捷盘、显示及外部通讯控制，为真正的数字可编程片上系统SOPC)。由于所有控制算法均用硬件实现，所以同服控制器可以达到相当高的性能，其电流环与速度环采样频率均可达到20kHz，位置环采样频率可达10kHz以上，频率指标主要由芯片本身性能限制。通过上位机可以访问所有内部寄存器，能实现各种控制目的。所有参数可以进行在线修改，包括开关频率、死区时间、调节器参数、滤波器参数等。适应于PMSM、IM、BLDCM等不同电机的驱动控制，并兼容霍尔传感器、增量式/绝对式码盘、磁编码器、旋转变乐器等各类传感器接口信号。可以接收脉冲指令、模拟指令以及数字指令等各种输入信号，并可通过上位机或控制面板完成所有操作功能，具有控制器识别码接口，易于实现多轴控制，这种单片控制器大大减少了系统体积，提高了抗干扰性，加上完善的保护措施，保证了系统运行的可靠性，

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.
