My ex-husband sent me the divorce agreement several days later; I signed my name on the agreement and I was single from then on. I had no job and no husband within several months. Things had changed so rapidly and I felt very sad. The first time I thought of was to go to the bar and drink beer to drown all my sorrows. I went on my motorized bicycle and went the nearest bar. I drank one bottle of beer after another and after a long time, I heard a voice saying that they were going to close the door I paid for the beer and went out of the bar. I had been drunk, but I could still remember my mamba brushless motor electric car and wanted to ride it home. I felt a little dizzy and could not see things very clearly in front of me. The guard saw me being unable to stand steadily and asked me to take a taxi home instead of riding the electric power bike and he would help me looking after the electric car. I followed his advises and stood by the roadside waiting for a taxi. 

What are electric bikes? E-bikes, as they’re called, are not scooters. They don’t travel at those speeds (most going at a max of 20 mph), and they have pedals just as regular bicycles do, which riders can use to travel at their own steam. When the terrain gets rough, cyclists either turn a key or push a button to engage the motor. E-bike doesn’t replace their effort, but it does allow them to cycle farther and faster with less exertion. These vehicles do not run on fossil fuels, so they’re a relatively “green” mode of transportation; a removable battery is the power source. “There’s no learning curve to using these bikes,” assures Dan Lehman, owner of the e bike tour company Austin Lehman, the first North American outfit to use these bikes widely on its tours. They’re very intuitive, with brakes that are the same as on a normal bike.

Compared with the frequency conversion AC motor, DC frequency motor is adopting permanent magnet which reducing the rotor induced currents and magnetic losses, so it has higher energy saving potential. As more energy-efficient products, DC inverter appliance is expected to become the future new bright spot of home appliance industry; DC inverter technology will become the most promising technology, and brushless inverter DC motor will certainly become the most popular frequency devices to achieve this technology.

As to the advantages of home appliances, the State Quality Inspection Center for household appliances Minister Lu Jianguo take Frequency washing machine for example, On the one hand, when fixed-frequency washing machine in the dehydration starts, the speed increase from zero directly to a high-speed, it is easily lead to vibration and produce noise. On the other hand, frequency water washing are water-saving and energy-saving.
