What is a servo oil pump motor? What role does it play? Dalan Motor tells you that the servo oil pump motor is the engine that controls the operation of the mechanical components in the servo system. It is an auxiliary motor indirect transmission. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The servo motor rotor speed is controlled by the input signal and can react quickly. It is used as an actuator in the automatic control system, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage, which can receive the received electrical signal. Converted to an angular displacement or angular velocity output on the motor shaft. Servo motors are divided into two types: DC servo motor and AC servo motor. The main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the rotation speed decreases uniformly with the increase of torque. The servo system is an automatic control system that enables an output control amount such as an object's position, orientation, and state to follow an arbitrary change of the input target. The servo is mainly positioned by pulse. When the servo motor receives one pulse, it will rotate the angle corresponding to one pulse to realize the displacement. Because the servo motor itself has the function of emitting pulses, the servo motor will respond correspondingly every time it rotates by one angle. The number of pulses. This forms an echo with the pulse received by the servo motor, or a closed loop. In this way, the system knows how many pulses are sent to the servo motor, and at the same time, how many pulses are returned, so that the rotation of the motor can be controlled very accurately. In order to achieve precise positioning, it can reach 0.001mm. DC servo motors are divided into brush motors and brushless motors. The brush motor has low cost, simple structure, large starting torque, wide speed regulation range, easy control, maintenance, but inconvenient maintenance, electromagnetic interference, and environmental requirements. The brushless motor is small in size, light in weight, large in output, fast in response, high in speed, small in inertia, smooth in rotation and stable in torque. The control is complex, and it is easy to realize intelligence. The electronic commutation mode is flexible, and can be square wave commutation or sine wave commutation. The motor is maintenance-free, has high efficiency, low operating temperature, low electromagnetic radiation and long life, and can be used in various environments. AC servo motors are also brushless motors, which are divided into synchronous and asynchronous motors. At present, synchronous motors are generally used in motion control. It has a large power range and can achieve a large power. High inertia, the highest rotational speed is low, and it decreases rapidly as power increases. Therefore, it is suitable for applications with low speed and smooth operation. The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electric motor controlled by the driver forms an electromagnetic field. The rotor rotates under the action of the magnetic field. At the same time, the encoder feedback signal from the motor is supplied to the driver. The driver according to the feedback value and target. The values ​​are compared to adjust the angle at which the rotor rotates. The accuracy of the servo motor is determined by the accuracy of the encoder. ----- Responsible Editor: Dalan Oil Pump Motor 02- Purchasing Consultant Copyright http:/(Dalan Motor) Reprint, please indicate the source http://news.chinawj.com.cn
