Depends on the system design and the usage. If it never gets overly warm or hot (so the plastic of most gears doesn't soften, causing the most typical of gear failures), then the clutch itself (especially for roller-ramp types) is vulnerable to torque spikes, which can either cause slippage (and flattening-wear of the rollers, so further wear is more likely to end up in the same spot) or even crack the clutch body. Can also just shear gear teeth off.
I snapped keys by just increasing the amps I believe it's just a matter of time before it goes.
So... you juiced your motor way past its rating, and now it's somehow not your fault you lunched it?
better the key than critical parts of the motor that are much more expensive / difficult to replace.
If they are that fragile will stay with direct drive.better the key than critical parts of the motor that are much more expensive / difficult to replace.
Reversing torque is a bitch. Don't do it, is my advice.
I just changed from a 13 amp controller to a 26 amp the old controller would not let you use throttle until 5 mph. Probably to keep from breaking something. You load down a geared hub enough they will give out.
That would be fine if you don't have to disassemble the motor to fix it, which is kind of a bitch in the field.better the key than critical parts of the motor that are much more expensive / difficult to replace.
