For an electric motor bike of 130 kgs to travel in urban area, How much Kilo Watt BLDC Motor @ 48 Volts excitation is to be selected? Instead of using permanent magnets can you use electro magnetic in the rotar? My drone had XGW_ESC VER2.4B controller with motor soldered in: Brushless motor has three wires: red for power, black for ground and yellow for signal transmission. This looks like a great motor, I’m impressed that you can DIY something that works so well! 3. Custom Magnets received  and tested by heating up to 120 Celsius to see if  any drop in magnetic field occurs. Once everything is ready, we can start coding! speed of motor and max. can you give me some advice ? border: none !important; Hi, Cogging torque. The overall quality of the print is important, of course, but the glass transition temperature depends on the material used, not the quality of the print. I am in agriculture business and I would like to attach some DC motors 22kw to my pump 18kw. will hope that you. Please, where can I buy the parts to assemble this engine? what software you used to calculate this motor ? Eulogy To Arecibo: With Demise Of A Unique Scientific Facility, Who Will Carry The Torch? If you would like to view or join in the project, please go to this link. We're a place where coders share, stay up-to-date and grow their careers. waste your traffic, you can earn additional cash hello ,sir plz i wont to your winding diagram full photo,plz send me my e mail. I’ve special ionterest in following points you mentioned: As a power supply for brushless motor I used 11.1V 2200mAh 25C LiPo battery with pins and terminal output: Looking at ESC, it has three main wires we should care about: red for external supply power, black for ground and white marked with PPM (in my case). Sunt placut surprins de realizarile dvs. I would be happy to pay for the CAD file. Is it possible to have all on at the same time? Per http://www.ecnmag.com/article/2011/03/integrate-flat-wire-inductors-high-frequency-high-current-designs flat wire provides more volume/density. Torque at motor bike wheel touching the road surface is. Learn how your comment data is processed. 14 magnets motor means 7 pole pairs. Neodymium magnets needs a coating otherwise they will rust in contact with air. I decided to make a reverse outrunner motor design because is more easy to cool the stator if is outside. Custom cut, N35UH grade, Phosphate coating magnets, Because the laser shop in Romania only had M330-50 grade, i was forced to use this material with higher losses for high RPM (frequency). Felicitarile mele pentru realizarile deosebite, ma bucur sa vad ca acest material este scris de un conational. This code uses PMW(Pulse-width modulation) to initialise ESC pin with 50Hz frequency, and change duty cycle to 7.5%, sleep for 3 seconds and stop. 7. admin. Somebody copied the motor and made some wrong changes which made the motor to produce much less torque than the original design. How to build your own motor and controller. Previous article Electric Bike From Car Parts / Homemade E-bike / DIY. Mind you he’s using an Ultimaker 2…you get what you pay for (which in this case is over $2k) :D. price and quality really isnt connected above a certain minimum for the application, many of the “premium” products aren’t any better than the average. | Hackaday, EV Motor Not Powerful Enough? Hello, congratulations on your project and make it available for everyone here. thats Awasome Is it possible for me to get templates / drawings of the motor frame and laminations to build my own motor from your design, I would also like to build the controller and install the pair in a car here. And… sorry..another one. A good winding scheme calculator can be found. Built on Forem — the open source software that powers DEV and other inclusive communities. How do you thermally connect the core and the copper cooling tubes ? •Optimizing the magnet pole arc or width, Hi Iulian, Brusless motor ready for testing under load. Motorul electric de 45KW prezentat de dvs are un raport greutate putere remarcabil 17Kg/60CP=0,284Kg per CP (cal putere). of poles/2). What a beautiful job. Speed is assumed of 130kmph on flat road ( 0 slope) and 25 kmph on uphill gradient of 45 deg. Gradient resistance force= 0 N on flat road and 2800 N on 45 deg slope Trimite-mi un email sau un mesaj pe facebook ca sa discutam mai multe detalii. how is the dimention of this motor laminations grade m330-50. A summary of techniques used for reducing cogging torque: Brushless motor simulation 45KW 0.2mm lamination and 0.75mm airgap. I am interested in your motor Sorry for so many question, but your work is very impressive and inspiring.
