When you opened this topic I understood you to say the bedroom was on a fuse. That's what fooled me. Did your 1800 watt dryer have a plug like this? I'm sure it's against the National Electrical Code for a manufacturer to use a plug like this on a device that draws more than 15 amps. Even if on...

Uh-oh... I guess getting cooked would result in (9), a short or grounding in a stator winding. :)

I think the word is not "sustained" but "planned." Watts depend on voltage and power factor as well as amps. Breakers and fuses care only about amps. The NEC is about planning. It says a home circuit shouldn't be intended for more than 80% of the breaker or fuse rating. That gives the homeowner...

I know from experience that the loss of a phase through poor contact will cause a 3-phase AC motor to overheat. I wanted to be sure that this was also true of magnet (brushless DC) motors. Found it! Here are the 18 reasons a brushless DC motor may overheat...

Did you check battery terminal voltage? Naturally, charger voltage has to be a little higher than the battery it's charging. My charger reads 54.49 and charges the battery to about 54.05. Another charger is too sophisticated to measure, but it charges to about 54.45. If your charger won't get...

That rang a bell. The source I found was apparently riding an ATV. When he hit a bump such as a root, he'd get that code and the motor would shut off. When I said it was over current, I wrongly attributed it to him. He said he thought it was over voltage. He said it happened only at full...

I wonder why your display doesn't simply show the battery voltage. I wonder if all C3 displays are like that. I've put KT controllers and displays on two bikes. I'd recharge at various levels. I'd note the display voltage, remove the battery, note the multimeter voltage, charge it, note the...

https://endless-sphere.com/sphere/threads/sabvoton-error-02h.113916/ This fellow discovered it means "overcurrent error." In an industrial AC motor, the magnetic fields of the three phases interact to produce torque and back emf, which limits current. If bad contactor points prevent current on...

It seems the motor. I'll bet @harryS could tell you how to check for overheated magnets and windings.

I was thinking of putting one of these on my bike. https://www.amazon.com/bayite-Digital-Current-Voltage-Transformer/dp/B01DDQM6Z4/ I would expect a 2.3 battery volt drop at 15 or 20 amps, depending on how your battery pack is made. If you're not getting much power, I imagine there's a short in...

I say again. Torque comes from amps. The strength of a magnetic field depends on the amps and determines torque. I see he uses a 6% hill as a mathematical example. They're fun with the motor off.

An extra 5 amps will help with torque. Torque comes from amps. The wattage of a motor is a manufacturer's classification. The maximum power delivered to the motor depends on the controller and the battery voltage. I think 24 amps is typical for a bike labeled "750 watts." If a battery with 4...

I've had that happen once when I let the battery get pretty low and again when I let the cells get badly out of balance. The motor didn't get hot. I think OH2 means the motor got too hot, as you observed. AFAIK, a battery problem won't cause that. I believe your kit uses torque sensing. My...

Gross weight, grade, and tire diameter determine torque need. Suppose you and your bike together weigh 250 pounds. That's 1113 Newtons. The sine of 25 degrees is .42, so you need 1113 x .42 or 467 N. The axle of a 27.5 inch wheel is 35 cm off the ground. 467 x .35 =163.45 Nm. A hub motor would...

Aah, transporting livestock... One morning in fifth grade a classmate arrived an hour late with an excuse note from his mother saying he'd had to take the cow down the road to be serviced. The teacher asked, "Couldn't your father do that?" "I think the bull does a better job."

I had a load of logs on my Abound. My gross weight must have been at least 450 pounds. I encountered a 16% grade in tall grass. The ground was soft from rain, greatly increasing rolling resistance. If the 750 watt motor wouldn't do it, I'd be struggling to push the bike. With just a little...

I've loved Worcestershire sauce since I was 3 or younger. It's made of fermented anchovies.

I never heard of rotating tires on a bicycle. In 1970 I found that it was a bad idea on a motorcycle. The classic BMWs had interchangeable wheels, which could run identical tires. Because they were wearing differently, I pulled the axles an swapped the wheels. The first time I leaned to corner...

I must have had about 2800 miles on my Kenda knobbies when I sold the bike. The tread didn't look badly worn except that some green was showing through on the right of the back tire. That's because right turns are tighter than left turns.
