Hy guys,
I have been "cooking" a lot in this summer,
Recently i embarked in a project with TUCN Racing Team (Technical University from my town), to build a custom motor and a controller for they're electric solar car, in order to compete in the ilumen European Solar Challenge 24h endurance race, on Zolder Circuit in Belgium this autumn (21.09.24). The race experience was a blast !, we finished the race !
Now the technical stuff, i had to design and built a large outrunner BLDC, that would have a power rating no more than 5KW continuous, at least 95% efficiency, it have to have strong bearings in order to support the back wheel (vehicle has 3 wheels), and propel the vehicle with a max speed of about 100Km/h.
I did some research in how others do it first, learned some lessons, and then did my own design. One of the requirements was, i have to use a common/ standard type/size of wheel /rim, to be bolted on the motor.
So, the outer diameter is 261mm, is a 32 pole, 36 slot motor, the stator is made from 0.2mm laminations. One nice thing is that the Technical University has they're own machine shop, so they did inhouse machining of the parts to cut off the costs.
In September (3 weeks before race) the parts came in to me, one week later had the motor done and tested.
I'l talk with the team if i can disclose photos of the vehicle, and more detailed technical details of the system.
Here are some pictures with the motor for now.
