How do you calculate Kv to RPM?

Kv – RPM Constant To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.

Is higher or lower Kv better?

Generally speaking the more Kv a motor has, the more RPM and more power. A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.

What does Kv mean on a motor?

constant velocity
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.

Which is faster a 9000kv motor or a 2200 Kv motor?

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 big is the 2200kv 75mm brushless motor?

Traxxas 2200Kv Brushless Motor Specifications: Type: Sensorless Brushless RPM/Volt (Kv) 2200 Weight: 406g (14.32oz) Length: 75.5mm (2.97″) Diameter: 41.8mm (1.64″)

Which is stronger a kV or RPM motor?

Kv is to be compared to rpm only, a small tiny motor with 20000kv on 150W is still weaker than a big 3000W 1800kv motor. Lower Kv motor allows you to run higher volt which allows you to run higher watts without having to increase current so much.

Is the turnigy outrunner 2200kv a good motor?

Nice little power plant! Been a great little motor. Installed in a small boat. Doing great after multiple packs. Fast. This Turnigy 2200kv motor will get your foamboard planes really moving. I have flown it using 3s and 4s batteries. It really gets up and goes on 4s. Haven’t burned one up yet on 4s even though it is rated a 3s motor.
