I am planning an EV conversion and have been looking at different motor options that would be feasible to use. One possibility that i have been investigating is using a standard industrial motor. The main limitation encountered with these motors are the weight and the rated rpm and hp. On another forum there has been discussion about rewiring a standard motor for a lower voltage and then driving the motor at a higher frequency to obtain the needed rpm and hp requirements. In theory this should work, but some unanswered questions remain. What efficiency loss will be experienced as a result of this modification? Will ther be increased I2R losses? What about any other losses due to magnetic changes. What increases could be achieved with a standard 230/460v, 1800 rpm, 15 hp motor. Ideal parameters would be in the 5-6000 rpm range with a rated hp/kW rating of 40-50. I greatly appreciate any advice, help, or smacks in the face to wake me up from a possible dreamworld scenario.(adsbygoogle = window.adsbygoogle || []).push({});
