Q:Is the brushless dc motor a synchronous motor or asynchronous machine? Thank you very much!: Motor classification: dc motor and ac motor are one level, and ac motor is classified with synchronous motor and asynchronous motor.

Q:The difference between dc brushless motor and ac servo motor: Simple dc brushless motor can not do position control and can only do speed control. Ac servo can do position control and other kinds of control.

Q:Dc motor input direct current, after the commutator, does it change to alternating current?: Dc series motors can be used for communication. In theory, the motor is the same, but I haven't tried it myself. Dc has direct current, communication is good. Otherwise you're only developing one.

Q:How does the current transformer in ac motor work?: The differential protection of ac motor is in the three-phase power supply (cabinet) of the motor, which is equipped with three current transformer: A1, B1, C1. At the end of the three-phase winding of the motor, there are three current transformers: A2, B2 and C2, before being linked to "neutral". The six current transformers are the same, and the secondary winding receives the differential protection relay. When the motor is working, A1, A2 is equal to zero, the difference is zero, and the differential protection relay has no output. (B1, B2, C1, C2) The proposal: still seek a book to see, as the electrical design personnel, should have more in-depth understanding, the Internet is difficult to get.

Q:Ac motor 110KW how much current: Consider the line current, according to the formula of three phases power: P = 1.732 * 380 * I * 0.75 According to the 110 kw to calculate: 110kW = 1.732 * 380 * I * 0.75 I = 110kW/(1.732 * 380 * 0.75) = 110 kw / 493.62 = 223 A The starting current of the motor is greater than the rated working current, which is four to seven times the rated current

Q:The same power ac motor is more expensive than the dc: Is the same power ac motor more expensive or more expensive? The price is of course the dc welder. But you welding, non-ferrous metal or welding have special requirements that you must use dc welding machine, because it has high no-load voltage. The arc easy. Wide range of welding current. Steady arc. The weld appearance, etc. If you weld a regular iron plate that's all you need to do with the ac welder.

Q:What are the advantages of the dc welder and ac welder? The better one?: compared with ac arc welding machine, dc welding arc stability, not easy broken arc and small six, splash. Dc arc welding machine can weld acid and alkaline welding rod, communication can only seven alkaline welding rod, welding machine prices, see you need to how much current welder, relatively speaking, dc welder expensive eight. Very save electricity, dc arc welding machine, is the development trend in the future. Personal recommendations dc welding machine. There is one of the biggest advantages is the dc welding machine is very light, 200 a to ten catties of convenient also move '

Q:Dc motor and ac motor, which is better for mechanical hands?: The manipulator USES servo motor and pulse motor to be controlled accurately.Dc motors should be used in this way.

Q:What is the power of ac motor: Three-phase ac motor, three phase ac motor rated power = square root of 3 x x x rated current x rated voltage power factor efficiency.

Q:Is the ac servo motor self internal speed control: A single servo motor can't work, but a servo controller can tune its own internal controls. General servo motor is the corresponding servo controller. Ac servo motor can be connected to the microcontroller, when the microcontroller will be sent to the motor speed value, servo motor will be done in its own internal speed, compare actual value with the given value and the rate of change in. A single servo motor can't work, and unlike the normal three-phase asynchronous motor, the power is turned. The servo controller is fitted with the servo motor system, the internal coder is a closed loop control, the speed is accurate, the torque is large and the resolution is high. The actuator input pulse, or the analog quantity, the serial port communication, can control the movement state of the servo motor. The frequency conversion is mainly the speed adjustment, while the servo is mainly position control.
