What are kv?
Answer: “Kv” refers to the constant velocity of a motor (not to be confused with “kV,” the abbreviation for kilovolt). It is measured by the number of revolutions per minute (rpm) that a motor turns when 1V (one volt) is applied with no load attached to that motor.
What is KV RC motor?
The Kv rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. A motor with a higher Kv will have more top end speed, but not as much acceleration/torque. A motor with a lower Kv will not be as fast, but will accelerate faster and have more torque.
How fast is a 540 brushed motor?
This RTR off-road Buggy gets up to 45+ mph or 72+ km/h. It’s a 1/18 scale model with a powerful, upgraded 540 brushed motors powered by a 7.4V 1500mAh battery. The car has impressive acceleration and stopping power as well as its insane top speed.
How many KV is a 13.5 motor?
Like I said prior, my 13.5t is between about 3000-4000 kv, but thats just a general range.
What kV motor is faster?
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. If Kv is like horsepower, then Turns is the physical attribute of a motor. The number of turns indicates how much wire is wrapped inside the motor.
How do I choose a kV motor?
The KV value can be determined by the number of copper wire windings on the stator. Generally the higher number of winds decreases the KV of the motor, while lower number of winds increases the KV. The magnetic strength of the magnets can also affect the KV value, stronger magnets will increase KV.
What Kv motor is faster?
