Guys, this is your motor running with our OpenSource firmware! I was using a throttle on that test.
So, since the other last video, seems that what is missing right now is "connecting" the torque sensor signal to the motor "throttle" signal, right?? Not yet, first I need to be able to read motor current and limit it to the max recommended value to this controller or the mosfets will burn
What I did learn that may be important for you:
- the controller can run with a battery pack from 7S (24V) up to 14S (52V)
- seems that all controller versions have the same hardware but for instance, brakes and throttle wires are missing. Don't know about the original firmware but our firmware should support all options (so, every controller version will work with or without brakes and throttle)
The test I did:
At 36V battery voltage, the measured time on hall sensors for 1 ERP was 1.94ms.
Motor has 8 poles, so the measured speed in RPMs = 60 / (0.00194 * 8) = 3866 RPMs.
Voltage
• Controller can run the motor from 20V battery input up to at least 60V (this values were tested)
◇ 20V will work for a 7S battery (min voltage per cell = 2.86V)
◇ 60V will work for a 14S battery
◇ controller capacitors on input voltage line are rated at 63V
