As a result of the failure of the brushed hub motor on my Evader EV100S, I am in the process of installing a brushless hub motor. The motor is a 1500 watt unit with a controller, all from GreenEMotor.
The motor has been fitted up mechanically and I ran some quick tests today to make sure everything is working OK before I finalize the wiring. While it did run, there were some questions that resulted from checking various voltages during the testing.
The throttle is a 0-5vdc hall-effect type. The supply voltage from the controller is 4.3v and the maximum controller output voltage is 3.7v. Normal? 2 things come to mind. I need the full 5 volts to see the maximum speed of the motor and at throttle wide-open, the output voltage should match the input voltage. That was the way with the brushed motor and controller.
The phase-to-phase voltage was 37v. The input voltage to the controller was 52v (48v nominal voltage). Should the phase-to-phase voltage be this low?
Thoughts and advice appreciated.
