I just had my second electric motor fail. The sprinkler pump failed. This is a two year old pump. At some point it ran with either no, or insufficient water pressure. Also decorative bark intruded into the ventilation holes likely damaging the rotor or its bearing.
It was an expensive part to replace, but at current temperatures here in Boise metro, you have little choice to save the beautiful green lawn and flowers. We will be putting some window screen over the ventilation holes to prevent a repeat bark invasion.
I've had quite a few electric motors fail. Engine starting motors, fan motors, vehicle accessory motors, aerator motors, electric tools, appliance motors, etc. I've lost count, but actually more than a few. But I've never had an ICE stop running due to a failure in the engine itself, as opposed to the electrical or fuel systems.
ReplyDeleteICE manufacturers powertrain warranties are generally 5 years/60,000 miles. South Korean manufacturers are an exception at 10/100,000 for original owner.
ReplyDeleteEV manufacturer powertrain warranties are 8 years/100,000 to 150,000 miles depending on the vehicle.
I have 27yo Jeep TJ that’s still chugging along, but I think EVs will dominate simply because they are simpler and mechanically more reliable.
I see this point of the transition as similar to the transition from piston-driven propeller aircraft to jets in the late 1950s and 1960s. Piston/Propeller fighters/bombers/transports were just about maxed out at end of WWII; jets were not very well developed, but everyone could see they offered more performance in the long run. Now ICE tech is at near zenith, EV still has a lot of room for improvement. The infrastructure for EV is still limited, just like for early jets, but it will expand rapidly. ICE won’t go away entirely, but will be a niche for certain tasks and for pleasure, just like prop planes are today.
