The philosophy of the walker
I. Communication of the power motive for walkers
Interacting an electric motor for the operation of voltage is widely used in electric fans, refrigerators, washing machines, air conditioners, electric blowers, vacuum cleaners, smokers, dishwashers, electric stitches
Domestic appliances such as sewing machines and various electrical tools and small mechanical equipment。
The motivations for the exchange of electric insulation are divided into those for the induction of electrical power and for the exchange of electrons. The sensory motors are divided into single-step electric motors, two-purpose electric motors for the direct flow of power, and motors for the push。
The electrics are rotated at a rate smaller than that of the spinning magnetic field, which is called a walker. It's basically the same as the sensors. S=(ns-n)/ns. S for change rate
N for the rotation。
Rationale:
1. When a three-step machine is connected to a three-phase exchange power, the three-phase magnetic motion (the fixed-rotation magnetic motion) generated by a three-constituent flow of the three-symmetrical current is generated by the three-phase magnetic motion。
2. The rotating magnetic field has a relative cutting movement with the rotor conductor generating induction electric motion and currents, based on the principle of electromagnetic induction。
3. According to the law of electromagnetic power, the rotor conductor carrying the flow is subject to electromagnetic force in the magnetic field, forming an electromagnetic rectangular, driving the rotor rotation, and exporting mechanical energy outward when the motor axis is carrying a mechanical load。
The scrambling machine is a communications machine whose load speed is not a constant ratio to the frequency of the grid. It also changes with the size of the load. The bigger the load, the speed of the rotor
Lower. The walker consists of sensors, double-responding walkers and exchanges. Sensors are widely used and generally referred to as sensors without misunderstanding or confusion
For a walker。
The fixed rounding grid of the general helo power plant is used to communicate the grid and the rotor rounding is not required to connect to other power sources. It therefore has a simple structure, ease of manufacture, use and maintenance, reliable operation and quality
Advantages such as smaller, lower costs. The walker has more efficient and better working characteristics, operating at close to constant speed from empty to full range, and meets most of the agricultural production machinery
The transmission is required. The walker also allows for the generation of protective models to accommodate different environmental conditions. When the walker is running, extract a non-functional magnetic power from the grid and make the grid work
The power factor is bad. As a result, synchronous machines are often used for high-power, low-rotation mechanical equipment such as drive grinders and compressors. Because the speed of the walker is the speed of the spinning magnetic field
There is a certain shift relationship, which is less velocity-reducing (except for exchange-replacement motors). In relation to transport machinery, rollers, large machine beds, printing and construction that require a wider and more peaceful smooth range
Paper machinery, etc., is more economical and easier to use. But with the development of high-power electronics and communication speed-retarding systems, the speed-referral performance and economics of a wide-speeding walker are ready
It's like a straight-flower。
