What is the most powerful electric motor for go karts?
Mophorn 1800 W Electric MotorThe Mophorn 1800 W Electric Motor is the best electric motor for go-karts in our list, due to its power, superb build quality and it’s high performance-to-cost ratio.
As the name already gives away, this electric motor has a power output of 1,800 watts, which is powerful enough for any type of go-kart..
Is lower KV better?
Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. … So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.
Do brushless motors have more torque?
Brushless motors have significantly higher efficiency and performance, and a lower susceptibility to mechanical wear than their brushed counterparts. Brushless motors offer several other advantages, including: Higher torque to weight ratio. Increased torque per watt of power input (increased efficiency)
Is torque directly proportional to RPM?
The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity.
How do you increase engine torque?
To increase the torque … that a bit harder. All you can do, electrically (as you can do it mechanically via gears), is to reduce the source impedance to maximise the current that can be delivered for a given stator impedance. Rewind it with more turns of thinner wire.
What is faster nitro RC or electric?
Brushless motors can also handle a lot higher voltage than brushed motors. With a high voltage supply, brushless motors can help a beginner RC race at blistering speeds. RCs equipped with brushless motors currently hold the fastest speed records for RC—yes, faster than nitro.
Are brushless motors more powerful?
Brushed vs Brushless Motors Brushless motors have become the industry standard in multirotor applications, and for good reason. Compared to their brushed counterparts, brushless motors are more powerful, more efficient and more significantly longer-lasting.
What is benefit of brushless motor?
1. More energy-efficient. Because there are no brushes rubbing against anything, no energy is lost due to friction. That means brushless motors are more energy-efficient than brushed drills and can run on batteries for up to 50 percent longer.
Does higher voltage mean more torque?
The higher the voltage, the higher the torque. The voltage rating of a DC motor indicates the most efficient voltage while running. … Operating torque is the amount of torque the motor was designed to give and stall torque is the amount of torque produced when power is applied from stall speed.
How do you calculate kV torque?
Therefore, the torque a motor produces is τ=KtI. The SI unit of Kt is the weber. So a lower Kv implies a higher Kt; a higher Kt means the motor will produce more torque from a given amount of current.
Is current proportional to torque?
The current in the output of a DC drive is the motor armature current, which is proportional to torque.
What is the fastest traxxas motor?
A longtime maker of such cars, Traxxas claims its all-wheel-drive XO-1 is the world’s fastest ready-to-run, electric RC supercar. It says the XO-1 can hit 60 mph in 2.3 seconds and exceed 100 mph.

How long do brushless motors last?
1,000 to 3,000 hoursIf you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.
How does voltage affect torque?
From the analysis above, we can see that when the load (torque) on the motor is constant, speed is directly proportional to supply voltage. And, when the voltage remains constant, an increase in the load (torque) on the motor results in a decrease in speed.
What is the fastest RC motor?
Traxxas XO-1“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds.
How do you reduce motor torque?
Theoretically, torque is reduced by the ratio of the base speed divided by the higher speed (60 hertz / 90 hertz = 67%). In real applications, other factors (increased bearing friction, increased fan loading, additional rotor windage, etc.)
How do I convert kV to RPM?
Kv – RPM Constant The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.
How is kV calculated?
The typical way to measure Kv is to spin your motor at a known RPM and then measure the voltage generated on the motor leads. … The formula to calculate Kv for a brushed DC motor is to just divide the speed by the generated DC voltage that you measure using your multimeter.
How is motor torque calculated?
The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque.
