- Q: Is the ac servo motor self internal speed control
- Can be internal direct speed adjustment, use dot move speed pattern, normally use PLC to send the PLS pulse, also can use a single chip machine of course
- Q: Ac servo motor can be divided into synchronous ac servo motor and induction ac servo motor
- The drip ac servo motor can be divided into synchronous ac servo motor and asynchronous ac servo motor Asynchronous ac servo motor is what you call induction ac servo motor
- Q: What is dc and ac servo motor?? What are the features?
- Input or output a rotating motor for direct current energy. Its simulation speed control system is generally composed of two closed-loop, speed closed-loop and current closed-loop already, in order to make the two can coordinate with each other, play a role, set up two controller in the system, adjusting the rotational speed and current respectively. Two feedback closed loop on structure by using a nested structure of ring set of a ring, this is the so-called double closed loop speed regulation system, it has the advantages of quick dynamic response, strong anti-interference ability, thus is widely used. Usually consists of a PI or PID circuit by analog transport. Signal conditioning is mainly used to filter and enlarge the feedback signal. Considering the mathematical model of the dc motor, the simulation speed control system dynamic transfer function relationship in the process of simulation of the speed regulation system debugging, due to the parameters of the motor or load mechanical characteristics have a great difference with the theoretical value, often require frequent replacement R, C and other components to change circuit parameters, in order to obtain the desired dynamic performance indicators, very trouble to do so, if applied by programmable analog device controller circuit, system parameters such as gain, bandwidth, and even circuit structure can be modified by the software, debugging is very convenient
- Q: MATLAB for ac asynchronous motor simulation, speed signal and torque signal when the result is negative?
- This shows that the parameters of the asynchronous motor have a problem, such as the rotor resistance and reactance of the motor. The load torque of the electric motor is too big, the machine can't bring up, so it shows that the speed is always going in the negative direction. You can modify the motor parameters, or reduce load torque
- Q: Please communicate the motor. It is possible to speed the speed with a governor
- Many household electric fans using bidirectional thyristor phase shift control of motor speed, this kind of speed is actually reduce the input current make motor with fixed running quickly and can only reduce the speed. Like dimming lamps, they are forced to regulate.
- Q: What happens to the ac motor plus dc
- If you add direct current, you don't brake, you burn it. If you want direct current to be alternating current, you can add a rectifier, a supercharger.
- Q: The ac motor doesn't have a brush so how does the rotor rotate?
- Ac motor rotor CaoGuan cast aluminum strip and at both ends to form closed circuit of the aluminum ring, when the stator magnetic field across the rotor conductor, a conductor is cutting the induced electromotive force resulting from the magnetic field lines and current. The electromagnetic torque of the rotor axis is formed by electromagnetic force, and the rotor is rotated by rotating field.
- Q: The speed regulation performance of dc motor is very good. Why need ac motor?
- Compared with ac motor, dc motor is very good at the speed of adjustment, but it is difficult to maintain the high cost and high cost.
- Q: Three-phase ac asynchronous motor load start and start up with airload start current who small, why?
- Motor in no-load and load conditions, start the moment for the operation condition of the motor are the same, the rotor is in stop state, starting current at this time also is same, after the rotor rotation, only the difference between no-load and load startup, reflect on the starting current, is the continuous length of time. There is a difference between direct current and ac motor. For ac asynchronous motor, the no-load and load the biggest starting current is the same, different is only the duration of the starting current and the current normal. No load and load startup, the rotor and the stator rotating magnetic field of the slip is the same, the current will be the same. Light speed is fast, short. The load speed is slow, with the length.
- Q: The vector control ac motor drive is the converter?
- Simply put, vector control is to decouple the magnetic chain from the torque, and the regulator of the two can be designed to achieve the high performance speed adjustment of ac motor. Vector control method is based on slip frequency control of speed sensorless vector control method of vector control mode, and has a speed sensor vector control mode, etc. In this way, a three-phase asynchronous motor can be controlled by a dc motor, which is the same as the static and dynamic performance of dc speed control system. So that's the encyclopedia. That's pretty good. The concept of vector control was first discovered by Siemens engineers in a graduate thesis, which is widely used in domestic inverters. The traditional V/F control is more advanced and the advantages are obvious. The current frequency converter also has a control called direct torque control (DTC), which is only done by Siemens and ABB, and the DTC controls are more advanced. Which one doesn't understand
