bike motor cd controller replacement

I would like to know if you sell the controller only, because I damage mine by over voltage and I need to replace it. Electric bike motor and LCD are still good. So please, i just need controller at the moment. The photo I'm sending from a copy of a invoice is just to give you full details of address info, the invoice is from other bike motor kit , not this. Can you make better price selling without LCD display ? I will buy more parts in future from you for sure. I have new projects in my mind. I already sent my e-mail today asking for the same model but with 60v (if this option is possible), if not possible no problem ,i will need to have another 48v bike motor controller, and change to a 48v battery again.. Im sorry, I said in last e-mail I had 8 x 12v lead battery, but my mistake,because in fact they are 10 bat, 12 amps +or- ,and 12 volts each. ( 2 box with 5 battery. each ) A lot of weight to carry, but i made already about 350 miles so far without any major problem...not bad homemade electric scooter…spend some money but i love this installation process, its a fine hobby for me. I ride it most of the time inside private property to avoid problems. I don't go fast, but uphill the controller burn…stupid mistake of mine..i push the controller limits.. many amps and some extra volts burn controller, almost in the end of the project.. I am your costumer for some time and I prefer your controllers because they are good and have regen break, very useful for me because i live in high place in Portugal, full of up and downhills. I also prefer the original parts from you because i know they will fit perfect on the Lcd display that i already have If yes , how can I pay you excepting credit card ? I can make bank transfer if you like, or another safe method for both. If I buy only bike motor controller I will pay less tax here also, less money in invoice is better for me because last time i paid a lot, also because motors are heavy , but only controller will be good, its lightweight for the post tax. If possible, don't mention watt power in invoice please, The hub motor has 1000/1500 watt power.. I can't remember exzacly, because sometimes display already showed 1200, 1300 watt instant motor power . maybe 1500w motor…not sure..

fan hub motor three frequency high-voltage electric tricycle china application

S mine fan hub motor three frequency high-voltage electric tricycle china application   Abstract: A crystal by controlling the frequency control to achieve a level, no level adjustment in the electric tricycle china installation and large-scale mine owners hub motor in the application. Keywords: three-conversion,electric tricycle installation Specificity due to the production of coal, the mine ventilation system related to mine safety in production, so the ventilation system in the coal production has a pivotal position. As long supply line, starting pressure drop, maximum protection devices for safe and reliable start-up and standby hub motor starter switch, the top priority is to enhance the system reliability.Coal Mine in NZ in November 2006, new investment and operation of the main fan hub motor for the GAF-type axial hub motor (check the hub motor by the largest coal mine in Asia through hub motor). The main fan motor 10KV 5000KW bldc motor asynchronous motor. In order to better address the project encountered in starting the impact on the grid, and the problem of load impact, the system used by the Power Electronic Co., Ltd production of three self-developed high-voltage electric tricycle china frequency equipment. 1, electric tricycle several Starting device Divided by the motor starter schematic: 1, reduced voltage starting methods. Traditional vacuum motor starting methods are Y-Δ start, decompression starting autotransformer, reactor start-up and so on. These methods belong to a class start decompression start, there are obvious shortcomings, the process of starting a secondary impact of current. The current high-pressure common way for liquid resistance starter starter, SCR series decompression start. 2, variable frequency start method. With the development of IGBT technology, high frequency voltage levels and larger capacities, but because of the price factor has restricted its development. Power Electronic Co., Ltd., on the basis of the SVC successfully developed three high frequency electric tricycle china, it has three characteristic frequency stepless regulator. 2, three frequency high-voltage electric tricycle china technical principles and characteristics High-voltage soft-start power supply and motor in series between the main circuit shown in Figure 1.   Figure 1 Main circuit diagram Three frequency high-voltage soft-start technology, the first SCR in series, then by controlling the conduction angle of SCR to achieve a level FM, and non-polar voltage regulator functions. Starting early by controlling the valve in the SA, SB, SC was to achieve a turn-on frequency 12.5HZ, the motor of 1 / 4 the rated speed when the control valve SA, SD, SE switch to 25HZ, the motor to achieve 1 / 2 rated speed, through the control valve SA, SB, SC to complete the full range of the switching process, and ultimately reach the rated speed, the bypass is closed off electric tricycle china trigger pulse to complete the starting process. Throughout the starting process in the three frequency points, while adjusting the frequency, change the output voltage to maintain constant voltage to frequency ratio, so that you can ensure that the entire starting process, the starting torque to keep the rated torque of 80 -90%, while the starting current can be controlled at about 2 times the rated current. Starting torque, starting current, is a three-frequency high-voltage electric tricycle china's largest technical characteristics. 3, S miners fan motor in the practical application. Coal Mine S is a new mine, it's power capacity is 35KV, 10000KVA, because the grid is responsible for the underground, Inoue electrical equipment supply, so the grid is relatively small margin, in order to ensure the process does not affect the start Other devices running on the main fan starting current requirements are very strict. And because it is located in the high-gas area, which uses negative pressure was high winds axial hub motor (two-stage fan is currently Asia's largest mining axial hub motor), the main fan motor power of 10KV, 5000KW. Throughout the starting process, showing the starting torque, starting current, a smooth start, the advantages of starting a short time. Measured data in Table 1.
