HI All,
I'm in a jam and would love anyone's suggestions on what to do next. If you live in the San Francisco Bay Area CA and think you can help, I'm willing to pay to get my Crown motor rolling again should you think it requires some case opening adventures.
In short, I think the current issue is related to damaged hall sensors, but feel free to suggest next steps. Feedback welcome!
Summary:
New Lyen controller (18 mosfet MKII) with modified traces. Crown T100 (fast wind) motor. Running 48V GBS Lithum batt setup. I've ruled out the power source in this case. Also running Cycle Analyst 2.25, but I’ve tested everything without any connections.
1. Wired up new controller and was working fine, but only 50amps. (Target is 80A, given modified traces).
2. Downloaded Software to update controller settings. Defaults set at: Phase Current 80A / Rated Current 40A.
3. I increased rated and phase incrementally by changing settings and downloading to Lyen controller successfully, and using Cycle Analyst to show me “actual amps drawn.” Test riding between setting changes.
4. Increases were…
rated: 40A, phase: 100A. (CA read ~50A using these settings).
rated: 50A, phase: 125A.
rated: 65A, phase: 150A (CA read 77A using these settings).
5. Test riding here I noticed that, upon throttle down regen seemed to enable, whereas it did not before.
6. After a speed test of 2 blocks, I pulled the ebrake (connected), came to stop. Nothing out of ordinary.
7. Throttle up and motor locked up, oscillating back-and-forth. All subsequent throttle makes the motor lockup. No heat on controller or motor, no smell, before lockup otherwise nothing!
TESTING:
1. Disconnected controller and testing with Clyte HS3540, spins up fine both directions.
2. Connected GrinTech 40A controller to Crown Motor, nothing, no spin (and no lockup), just nothing. GrinTech controller to HS3540 spins fine.
3. Checked Crown motor phase continuity: same level across all poles.
4. Lyen controller with Crown locks up with current settings (see attachment).
Thoughts:
Everything was working great until I went up to 36mph, then pulled the regen lever coming to a stop. Amps show on CA for regen showed something like 20A (my charger is max 6A). Battery pack is 40Ah and at least 2C charge so should take 80A charge rate at least for a short period?
The only unexpected part was that regen was applied by throttle-down, which did not seem normal, and then also when pulling regen something bad happened. It seems like the issue was caused by pulling regen switch.
I’ve since disconnected regen and ebrake. But motor does not respond. Ack! Help? What could be wrong?
Thanks in advance!
