I am a new member, please allow me to post on this forum. I am converting a 250cc motorcycle to electric.
I recently purchased a VEC600 controller and HPM10KV motor. When testing them the first time, the motor would start turning then stop after just a second or two. The light on the controller would flash 13 times indicating a problem with the thermal sensor. When I reprogrammed the controller to disable the thermal protection the motor seems to run correctly. The HPM10KV has two sets of Hall sensors and thermal sensors, so I tried the other set with the same results. The goldenmotor.com website has a spec sheet for KTY84 series silicon temperature sensor, which indicates that room temperature it should measure around 600 ohms. When I measure the the temperature sensor on the motor with an ohmmeter (from the white wire to the black wire) I get an open circuit in one polarity and ~30Mohm in the other. Both sensors measure the same.
Any idea how I can get the thermal protection working? I think I could easily overheat my motor, and that could ruin the rare earth magnets inside. I would really like to have this feature operating.
