It does not work like that!If I took a series dc motor and advance it how much would I be able to increase the voltage without doing damage? Since the higher voltage decreases needed amp would that cause less heat production?
They advance brush timing to increase the power available at higher motor speed, at the expense of lower power and efficiency at low motor speed. Like everything else in life, and especially in technology, it's a tradeoff.So why do people advanced them if there losing power by doing so?
NopeSo As I understand it if I give a higher voltage it'll pull less amperage to reach the same wattage does that change the output torque? And as I understand it would extend the battery life because the more amps you pull the faster the batteries drain right? and make the rpm higher?
Of course diesel fuel is ignited; "ignition" just means the initiation of combustion. The more generic name for diesel engines is compression-ignition engines, while gasoline engines are normally spark-ignition.So you're saying diesel don't loose power the higher the rpm?
Diesel is not ignited it combust from compression so how does that make power from higher rpm really work.
A heavy truck (such as a highway tractor with semi-trailer) weighs 20 to 60 tons loaded, and is driven by an engine only capable of a few hundred horsepower, and even that only at one specific peak engine speed. To make the most of the engine, many gear ratios are provided to keep the engine close to the optimal point.So why tf the they put so many more gears in the semis ?
That's not true. The speed of the peak torque of an engine depends on the specific engine design, including intake and exhaust tuning and camshaft profile. The big difference between common diesel and gasoline engines in low-speed torque production is that all of the diesels are turbocharged, and few gasoline engines are. If you compare a modern turbodiesel and modern turbocharged direct-injection gasoline engine of the same displacement at the same speed and boost, the gasoline engine will produce comparable or higher torque... but most people compare turbodiesels to non-turbo gas engines, or huge (6.7 L) diesels in pickup trucks to much smaller turbocharged gasoline engines.And gasoline don't get much power behind it until you get to a higher rpm
Regardless of type, electric motors are typically limited in torque by current, and limited to a fixed maximum current from zero speed to a significant part of the way up their speed range - that's the constant-torque region. At the other end of the scale, the current through the motor is limited by the available voltage at high speeds, as an increasing amount of voltage is required to overcome back-EMF at higher speeds. In-between, while the motor itself could be limited by current or voltage, in practice in EVs they are limited by the power that the battery or controller or cooling system can handle, so they are effectively constant-power (so decreasing torque with speed) over much of their speed range.Thank anyway I thouggt when they started electric motors was full torque and was all the way to top speed
