- Q: The three-phase ac motor can be divided into which classes
- Three phase asynchronous motors with different power supply: Can be divided into dc motor and ac motor, dc motor: dc motor, permanent magnet dc linear dc motor, brushless dc motor, ac motor can be divided into asynchronous motor, ac servo motor, ac torque motor, synchronous motor, ac motor. Second, classify the starting and running mode Motor can be divided by starting and running in a different way, capacitor start type single-phase asynchronous motor, capacitor operation type single-phase asynchronous WEG, capacitor start motor operated single-phase asynchronous motor and split-phase single-phase asynchronous motor.
- Q: How do I get 220v on the motor?
- If is to first of all should be low voltage motor step-down, dc motor need rectifier, filter, as needed if in ac motor is single-phase motor can be directly connected to the domestic load, is a set of three-phase motor single-phase electric into three-phase electric equipment. However, the typical three-phase motor is an industrial motor, directly connected to the industrial three phase electricity, while the civil motor is mostly dc motor or single phase motor.
- Q: Single phase synchronous alternator working principle
- The working principle of the dc generator is the armature coil alternating during induction electromotive force, the commutator with brush commutation function, make it from the brush end into the principle of dc electromotive force.
- Q: Which price is higher for ac motor and dc motor? Which service lasts longer?
- Accurately, if is the same specification, should be ac motor price is low, service life is longer, through electromagnetic induction ac motor rotors, relatively save electricity, and the internal heat production is less than a dc; Dc motor, the electric motor turns the electric motor, produces heat fast, but the effect is better. Therefore, you should choose according to the requirements when using.
- Q: Why does dc motor reduce the voltage regulating ac motor?
- To understand "why do dc motors reduce voltage regulating ac motors?" The first thing you need to know about their speed is what the parameters are. Three-phase ac motor speed formula: n = (1 - s) 60 f/p, can be seen from the formula, the speed of the three-phase ac motor with slip s very logarithmic p, power frequency f, motor, voltage has nothing to do with work. Dc motor speed formula: n = (U - IaRa)/(Ke Φ), can be seen from the formula, the dc motor speed related to the armature voltage U and excitation flux Φ. From the above two formulas, the dc motor can be used to adjust the armature voltage or adjust the excitation voltage to achieve the speed adjustment. Not while ac motor, ac motor can only by adjusting the slip s of wound rotor motor, asynchronous motor power frequency f, multi-speed motors of logarithmic to achieve speed control purposes.
- Q: The ac motor is not positive and negative, so how do you achieve positive and reverse?
- Ac motor? Single item of pole type electric motor does not turn positively! Three exchanges of any two phase sequence will be easy if you have more mundane motors!
- Q: Is permanent magnet synchronous linear motor is ac motor or dc motor?
- Permanent magnet motor, general is small dc motor, and ac motor, generally do not have dc small, the excitation that USES is line excitation also. It's not permanent magnetism. Like some razor, small motor is permanent magnet dc motor, some dc output of the generator, is also a permanent magnet, some also dc generator output, but it was all in after a dc generator output, and is not directly the output direct current.
- Q: Calculation method of motor torque
- There is a formula for your problem: Electrical power: P = 1.732 * U * cos phi Torque: T = 9549 times P/n; Power torque = 9550 * output power/output speed Torque = 9550 * output power/output speed P = T * n / 9550 The formulas The relationship between motor power, torque and speed Power = force * velocity
- Q: What is the speed of the general motors
- The motor synchronous speed is n = 60f/p n speed f power frequency p electromagnetism log. Common motor speed is 960, 1400, 2800 RPM. More.
- Q: What's the total number of ac motor governor? The most common, each principle, the detailed point, the master thank you Please be more careful, the principle means thank you
- Ac motor speed governor generally refers to the electromagnetic speed regulating motor controller. Now the gear speed machine, also called ac motor speed, the best you know that will you use it first.
