SANYO P30B04010PCKSTA01 交流伺服电机是一种微型电机，在自动控制装置中用作执行器，其作用是将电信号转换为旋转轴的角位移或角速度。伺服电机又称执行电机，在自动控制系统中用作执行元件，将接收到的电信号转换为电机轴上的角位移或角速度输出。伺服电机可以理解为绝对服从控制信号指令的电机:在发出控制信号之前，转子是静止的当发出控制信号时，转子立即旋转;当控制信号丢失时，转子可以立即停止。伺服电机的分类伺服电机分为交流伺服和直流伺服两大类。

SANYO P30B04010PCKSTA01 AC servo motor is a micro motor used as an actuator in automatic control devices. Its function is to convert electrical signals into angular displacement or velocity of the rotating axis. Servo motor, also known as executive motor, is used as an executive component in automatic control systems to convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. A servo motor can be understood as a motor that absolutely obeys control signal commands: before issuing a control signal, the rotor is stationary. When the control signal is issued, the rotor immediately rotates; When the control signal is lost, the rotor can immediately stop. The classification of servo motors is divided into two categories: AC servo and DC servo.

Advantages and disadvantages of DC servo motors: precise speed regulation, hard torque and speed characteristics, simple control principle, convenient use, and cheap price. Disadvantages: Brush reversal, speed limit, additional resistance, and wear particles are not suitable for dust-free explosive environments. The basic structure of a DC servo motor is similar to that of a general DC motor. The motor speed n=EK1=(Ja iara)/K1), where E is the armature back electromotive force, K is constant, j is the magnetic flux per pole, Ua and la are the armature voltage and armature current, Ra is the armature resistance. Changing Ua or p can control the speed of the DC servo motor, but generally the method of controlling the armature voltage is used. In a permanent magnet DC servo motor, the excitation winding is replaced by a permanent magnet, and the magnetic flux is constant. DC servo motors have good linear regulation characteristics and fast time response.

Advantages and disadvantages of AC servo motors: good speed regulation characteristics, stable control can be achieved throughout the entire speed regulation zone, almost no oscillation, high efficiency, low heat generation, high speed control, and high position control accuracy (depending on encoder accuracy)
Rated working area, capable of achieving constant torque, low inertia, low noise, no brush wear, maintenance free, suitable for dust-free and explosive environments. Disadvantage: The control is relatively complex and requires on-site adjustment of driver parameters to determine PID parameters, requiring more wiring.
