Electric Motor Torque Curve Vs Gas Engine

Electric Motor Torque Curve Vs Gas Engine. Electric motors provide instant torque, so they out accelerate any equivalent gas or diesel motor. A stronger torque curve means an electric motor has a lot of horsepower available at low rpm’s.

If turbocharged and hp is about same magnitude as torque, you will shift beyond hp peak, but not at redline. Given this, then a lower maximum power electrical motor might make the same power as a gas engine at lower rpms, if the gas engines peak torque is near 3/4 peak rpm. Now take a look at electric motor torque vs.

Nitro and gas engines have great power curves but the torque curve of an electric motor provides it a large advantage. Electric motors can out perform an internal combustion engine.

This is the metric equivalent of pound feet. Nitro and gas engines have great power curves but the torque curve of an electric motor provides it a large advantage.

In this chart, the torque generated by the electric motor is instantly at its max value. Electrical motors tend to have torque drop off almost linearly as rpms increase, while gas engines tend to have a torque peak somewhere between 1/2 to 3/4 of their peak rpm.

When looking at a gas or diesel engine the more work you need to be done, the bigger the engine has to be. Nitro and gas engines have great power curves but the torque curve of an electric motor provides it a large advantage.

With gasolline engines it’s different. Having a lot of horsepower at low rpm’s is a great way to get a heavy rc vehicle off the starting line.

The biggest difference is life, a 5hp electric motor can produce that 5 hp forever, until something fails anyway, a 5hp gas engine not so, it is rated as 5hp max hp, but a continuous hp of about than half that. But electric motors produce torque through the interaction of magnetic fields, and that interaction tends to be greater at zero speed than at full speed.

The biggest difference is life, a 5hp electric motor can produce that 5 hp forever, until something fails anyway, a 5hp gas engine not so, it is rated as 5hp max hp, but a continuous hp of about than half that. For most na gas engines, shift at redline for max acc’n.

So, What We Really Need To Be Thinking About Is Torque And This Brings Us To Why Electric Motors Are Better Than Gas Engines.

Torque of an internal combustion engine. An electric car makes the same amount of torque regardless of how fast it's traveling, while gas cars have what's known as a torque curve, a spot in the engine's power range where maximum torque is produced. If you want to tow 20,000 lbs with your truck you are going to need a whopping big v8 to do it.

A Gas Engine Rated For 7.5 Hp Continuous Duty Produces The Same Continuous Power As An Electric Motor Rated For 7.5 Hp Continuous Duty:

Now take a look at electric motor torque vs. What is different is the torque curve. The biggest difference is life, a 5hp electric motor can produce that 5 hp forever, until something fails anyway, a 5hp gas engine not so, it is rated as 5hp max hp, but a continuous hp of about than half that.

In A Good Design This Should Occur As Close To The Rated Slip.

Therefore, a 'high torque' engine may have the same peak hp as a 'low torque' engine, but the high torque engine will have more horsepower in the lower end of the rpm range. Electrical motors tend to have torque drop off almost linearly as rpms increase, while gas engines tend to have a torque peak somewhere between 1/2 to 3/4 of their peak rpm. With electric, a motor that will tow 5000lbs vs a motor that will tow 20,000lbs is often nominally bigger.

For Most Na Gas Engines, Shift At Redline For Max Acc’n.

Nitro and gas engines have great power curves but the torque curve of an electric motor provides it a large advantage. In this chart, the torque generated by the electric motor is instantly at its max value. With gasolline engines it’s different.

If Both Are Running A Conveyor All Day Long, Continuously Lifting Grain Up An Inclined Plane, And If 7.5 Hp Is Required For The Operation, Then Both Motors Will Have Done The.

Remember, electric motors don’t need to. A stronger torque curve means an electric motor has a lot of horsepower available at low rpm’s. But electric motors produce torque through the interaction of magnetic fields, and that interaction tends to be greater at zero speed than at full speed.
