- Q: The power consumption of a three-phase ac motor is equal to the line voltage cross current. How do you explain?
- The calculation formula of three-phase symmetric load; The power P is equal to the square root of 3 U line I cosine phi is 3I2R. The line voltage refers to the parallel voltage between the two phase lines (a-b a-c b-c), and the phase voltage refers to the parallel voltage of the relative zero (a-0, b-0, c-0). In a power distribution system that is directly grounded in three phase four lines; Line voltage is equal to phase voltage square root of 3, phase voltage is equal to line voltage over square root of 3, line current equals phase current.
- Q: Three-phase asynchronous ac motor electric speed formula?
- The three-phase asynchronous motor speed formula is n = 60f/p (1-s) F stands for power frequency P is the logarithm N 'stands for slip S stands for slip The three-phase asynchronous motor speed is graded, determined by the "extreme number" of the motor.
- Q: What is the electrical Angle in the motor? What does it have to do with mechanical angles
- Commonly used three-phase brushless dc motor, there are generally three position sensor, the output waveform has two kinds: one kind is phase difference Angle 60 ° electrical, the other is a phase difference of 120 ° Angle. 1 on the poles, for example, phase difference of 120 ° electrical point of view, three position sensor space interval is 120 ° mechanical Angle; 2 on the poles, phase difference is 60 ° electrical point of view, the three position sensor space interval of 30 ° mechanical point of view.
- Q: What are the advantages of the dc welder and ac welder? The better one?
- The biggest advantage of ac welder is that it is cheaper, and the advantage of dc welder is better than ac welder. Ac welder and dc welder are two types of welder's classification. Electric welding machine is the use of the positive and negative poles in instantaneous short circuit which is caused by high temperature arc to melt the solder on the welding electrode and welding material, cause the contact material combination of equipment. The welding machine can be divided into two types according to the type of output power Advantage of ac welder: cheap price; Disadvantages: high power consumption, low electric load (not easy arc), electric current instability, broken arc, sticky electrode, heavy, welding plain electrode. Dc welding machine advantages: low power consumption, high no-load voltage, current stability, easy arc starting), continuous arc, non-stick electrode, lightweight flexible, suitable for all brands of electrode; Disadvantages: the price is more expensive. Normally, dc motor is better than ac motor.
- Q: The type of speed adjustment of ac motor and the difference between them
- Variable frequency adjustable speed -- -- -- -- - this is by far the most common way of speed regulation, can achieve stepless speed regulation, after semiconductor converter circuit (or) change the frequency of the motor power supply, the mains frequency (= 50 hz) change as needed to achieve the purpose of speed regulation, frequency or the above formula: ac motor synchronous speed = 60 f/pole logarithm, th
- Q: What is the difference between a brushless ac motor and a brushless dc motor?
- The difference between brushless and brush is commonly used for dc motors. The ac motor does not have a brush and no brush.
- Q: What are asynchronous motors and synchronous motors
- The difference between asynchronous motor and synchronous motor is that rotor speed is different, the rotor speed of asynchronous machine is less than synchronous speed, and the rotor speed of synchronous machine is synchronous speed. Note: in the asynchronous machine, there is a rotating magnetic field at the same speed as the synchronous speed, the synchronous velocity is 60f/p, f = 50hz, and p is the logarithmic logarithm. Further excitation of the rotor of the synchronous machine; The asynchronous machine is not used, and can directly from the stator to the rotor.
- Q: How does the three-phase ac motor identify the phase
- What you're talking about is the traditional start of the de-stress In fact, there is a soft start and frequency converter
- 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
- Q: What is the normal current of the three-phase motor of 3KW
- The electric current formula of the motor Three-phase motor power 1 kw per phase 2 (ampere) current (ampere) = power (kilowatt) watts) * 1000/1.73 * force rate * efficiency Remark: power rate: 0.85; Efficiency: the rated current of 0.853 kilowatt motor is 6 times.
