tubular motor

Q: How to distinguish dc motor from ac motor?: Ac motor and dc motor two kinds big. (1) ac motor and its control ac motor divided into two categories, asynchronous motor and synchronous motor. The asynchronous motor according to the number of stator phase asynchronous motor is divided into single and two phase asynchronous motor and three-phase asynchronous motor. Three-phase asynchronous motor has simple structure, reliable operation, the advantages of low cost, widely used in industrial and agricultural production. 1. The basic structure of three phase asynchronous motor There are two parts: the structure of the three-phase asynchronous motor stator and rotor. (1) of the stator, the stator is fixed parts, motor function is used to produce a rotating magnetic field. It is mainly composed of stator core, stator windings and the frame. (2) the rotor, the rotor is the key to master the part, there are two kinds of rotor, squirrel cage and wound rotor. Master. Their respective characteristics and difference between cage type used for medium and small power motor (below 100 k), he has simple structure, reliable work, convenient in operation and maintenance. Wound rotor can improve startup performance and adjust the speed, size of air gap between the stator and rotor, will affect the performance of the motor, the general thickness of air gap between 0.2 1.5 mm. Grasp the connection method of stator winding

Q: Is the extruder in 110KW a good ac motor or dc motor?: Now we use frequency conversion to ac motor. Very few dc machines, because dc machines need to be maintained too often.

Q: Why should ac motors be used in parallel with capacitors: It is. The motor will not work. In order to be able to in the case of single phase can also produce a rotating magnetic field, the designers in multiple access a coil at the same time, through a capacitor on the coil, leading to join this coil phase voltage phase shift. So it's going to be a single phase in the outside and it's already going to be a double phase. The two phases produce a rotating magnetic field. The principle of connection is illustrated

Q: What does the motor center of the three-phase ac motor mean: Center height refers to the height of the motor shaft to the base Angle of the seat. The length of the machine is used in the international letter of the letters: the "S" - the short stand, the M - the engine seat, the L - the long machine seat, is usually determined according to the length of the stator iron core. The "H" of 80 is 80mm

Q: There is a difference between ac frequency conversion and dc frequency conversion: Dc motor brush and the cause of the volume, restricting its scope of application of frequency control of motor speed can be developed by the fan and water pump, is due to the needs of the fan and water pump energy saving, frequency control of motor speed is the best choice, but I personally think that the price of electricity and the inverter's own, compared to the energy saving is pointless, because of the frequency converter investment back, at least need 5 to 6 years, in the five or six years, working condition of don't know what will happen. Therefore, inverter is best applied to speed regulation, and start on the performance and torque adjustment is not very demanding, and the occasion, this is the reason in general use frequency control of motor speed. So you can say that if you use dc speed control controllers to control ac motors that's the best, you can do that, and it's very difficult right now

Q: What is the ac motor made up of?: The modern car is widely used in air-conditioning units, electric jet engines, electric control doors and Windows, electric adjustable seats, etc. The more advanced the car, the more power it USES. Today's mid-premium car generators are typically about 1 kilowatt. With the increase of automation and comfort, the use of electricity should be increased, but the installation space of cars is limited, and it is impossible to increase the power by increasing volume. As a result, engineers are working on cooling and installing positions. For example, install the generator on the top of the engine and try to stay away from the hot zone. The rear end of the generator is fitted with fan blades to enhance the cooling effect. BMW recently tried to improve the cooling effect of the generator by trying to cool it with water. The starter is made up of motors, actuators, and manipulators. Special start the engine, it needs strong torque, so want to through the flow of electricity is very big, hundreds of ampere, this feature determines it is different from the generator. For example, using dc series motor, the rotor and stator parts are made of coarsely rectangular copper wire. Driving mechanism adopt reduction gear structure; The operator USES electromagnetic magnetic absorption.

Q: How the ac motor works: Ac motor consists of stator and rotor, what you said in the model, the stator is the electromagnet, the rotor coil. The stator and rotor is to use the same power supply, so the direction of the current in the stator and rotor changes always synchronized, namely the current in the coil direction changed, became the current in the electromagnet direction at the same time, according to the left hand rule, coil by magnetic direction invariable, the coil can continue turn. About the role of two copper rings, two copper rings with corresponding brush, can continuously is fed into the coil current. The benefits of this design are

Q: Question about the general motors?: Naturally, it's alternating current and dc, so it's not positive, because the communication is positive and negative

Q: What will be the result of the power supply to ac motor after the rectifier (not filtering)?: The ac motor will not be able to transfer the pulse direct current, the light is hot.

Q: How to control ac motor with single-chip microcontroller: First, the output of the single-chip machine is connected to the photocoupler, plus the triode, and the circuit of the relay. Depending on how much voltage the relay corresponds to, the relay has to be connected at one end to the voltage, and one end to the triode. Finally, the ac voltage is suitable for ac motor at one end of the relay, ac motor on the other end, and two relays under control.
