Treadmill DC Motor For Electric Vehicle Project?
I am going to start a small EV project. I have seen that most treadmill motors are 3 to 4hp powerful. I wanted to know weather these motors will be suitable for my project. I am building a small kart capable of carrying maximum 2 persons. Also if they are suitable for my project please can someone suggest me 3 or 4hp treadmill motors on eBay or other sites below 150$. Also I saw a formula on a site related to power for a vehicle HP = W(V/234)^3 where HP=horsepower, W=weight in pounds and V=required velocity in MPH. I found this formula on this site (http://www.ajdesigner.com/phphorsepower/horsepower_equation_trap_speed_method_horsepower.php). Is this formula correct.
