I think if it becomes race of the motor control technology, the possibility of more power electronics / analog technology is good at standing on top as high. Because it is a natural motor control also to control by the microcomputer and now, who microcomputer software development are good might come to the top.
The (so-called finance qualifying) time attack, it will be a game of speed simply in front of the main race. What should I do the motor control strong in time attack? Motor that rotates at high speed I want. Having said that, the load is applied in the motor that can be rapidly rotating time if takes to reach the maximum speed from the stop state, and it will become the goal before reaching the maximum speed.
It is said that in the case of low-speed running, and affected by the rolling resistance than air resistance. Devised to reduce the rolling resistance of the tire is also effective. It is said that if accustomed to run at speeds in excess of 30km per hour, then the better the air resistance to affect greater than rolling resistance. If you aim for the championship, air resistance is not reduced considerably and put the (OK to body length 2.5m) cowl streamlined. However, you need to ponder the weight of the cowl also worth it increases. Ogata, Akita Prefecture finance of the race venue, seems to be famous as the place where a strong wind blows. Weather conditions finance of race day also might affect the big race.
Further, in the body of a Type A Ackerman system, wheel alignment of the front wheel that allows for adjustment. In other words, 'Gyakuha' di-or 'c' is the front wheels of the two when viewed from the front of the (body camber finance angle (angle to also outside or within or the front wheel of the two as seen from the top of the body) Two angles of the car can be adjusted, such as angle) to be in character finance (Figure 1). With these, I can adjust the performance meandering finance and straight performance. Please adjust taking into account the situation of course.
The reason for the hand-rolled coil 7 photos and unexpectedly fun! While not become fast motor if I wind a lot but ...
The CQ brushless motor and inverter kit, there is a control board of the V850 equipped with the inverter board, software primitive is available (varying the duty ratio of the PWM control) to change the rotation frequency in the volume of (C all with source code). However, software mini carts are not available. Software or explore the optimal inverter for control of the cart, or a limit of current, the software for regenerating, finance please develop your own if. The motor and inverter kit, development of the microcomputer environment is also included. In addition, the changing to another microcomputer from V850 microcontroller motor control it is also OK.
By the way, Do not worry some people that there is no confidence in the EV for microcomputer software development. Even if assembled finance as it is CQ EV mini Kurt Kit (only software finance + initial installed) CQ brushless motor and inverter kit, moving the cart (but a little too much the number of turns of the coil) that you can. Speed may take you about 5-6km / h in level ground. However, I will heat generation on a slope a little. In addition, it is possible to power up the MOSFET, if you stick a heat sink (radiation fin) and there, pick up the pace even more, you may climb the gentle slope. Can either be performed slowly with trial and error of software development for EV. About the battery
The CQ EV mini cart kit, (12V, 8Ah) shield finance of 12V lead-acid finance battery comes with two. In the race, in order to maintain fairness, the supplied two (Furukawa Battery finance FPX1275) 12V of equal condition, lead-acid batteries of 7.5Ah from convention secretariat, use the battery with the main race and time attack. Charge during or replace the battery that has been paid is not permitted, you must note the use of energy. In addition, it is different from the battery that comes with the mini cart EV kit also need to be careful.
