Watt's work was remarkable, and to honor him, his name was given to the unit of power, the watt no, he didn't invent the light bulb, but his name is on every one. Watt was working in a mine, using horses to pull wagons of coal. He wanted to determine how much coal a pony could pull in a wagon over a given length.
He measured how many feet a horse could pull 22, pounds of coal in one minute. He then increased that amount to 33, foot-pounds in a minute, and called it horsepower. It's a perfectly arbitrary amount, but it became the measure of how much work engines could do — no one had ever measured this before.
So, imagine a horse pulling a wagon of coal out of a mine; with 1 horsepower of effort, the horse pulls pounds of coal feet in one minute. Horsepower is measured by a dynamometer, which is a rotor in a housing. It takes a certain amount of power to make the rotor go around at a certain speed.
If you put a car into neutral, and then floor the engine while it is attached to a dynamometer, the device puts a load on the engine and sees whether it can turn the load or how fast it can turn the load around.
If you run the engine at rotations per minute, rpm , you see how much load turns on the dynamometer to calculate horsepower. Every engine has a peak horsepower — an rpm value at which the power available from the engine is at its maximum. You will often see this expressed in a brochure or a review in a magazine as " HP rpm". Gross horsepower is a measure of the work output of an engine on just a dynamometer, when the engine is not connected to the usual accessories apparent in a running car.
Net horsepower measures engine output when connected to belt-driven accessories such as water pumps, power steering pumps, and alternators.
There are also parasitic losses in power caused by transmission drag and clutch or converter slippage that net horsepower takes into account. As a result of powering these moving parts, net horsepower can be considerably lower than gross horsepower. Torque is defined as a rotating force. It's measured as the amount of force multiplied by the length of the lever through which it acts. Max Speed: 20 mph depending on weight of rider Forward and Reverse: Yes. Driving System: Chain Drive.
Brake System: Disc Brake foot control. This High power Go-Kart also can be adjusted down to go a maximum of 5, 10, or 15 mph with the parental key that is included, simply turn the key to low and remove it for example and it restricts the kart down to where the child cant go faster than approx 7 mph for safety.
Any car at any weight at 48 volts will go exactly 0 mph. You need current and voltage to get to power, to get a vehicle to move. That is So up to that speed, you can hit the throttle and get an assist.
It was quite weird when going down a long, steep downhill to hit the throttle and feel the motor provide even more speed.
Re: How to use a 60v battery pack on 48v motor You need to know the max voltage charge of your 60V pack to determine if it will work with your setup. At worst, you will need a new controller, but if max charge is 60V, then it will work fine without a problem.
In my experience, watts is perfectly fine on flat ground, can hand hills if you pedal along, and have some nice benefits including a quieter motor, lighter weight, and a cheaper price tag. Wattage ratings on electric motors indicate how many watts the motor can use.
