Question: What does the KV rating on a motor mean?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. 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.

Is higher or lower KV better?

A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop. A high Kv motor has fewer winds of thicker wire that carry more amps at fewer volts and spin a smaller prop at high revolutions.

What does KV mean on brushless motors?

The Kv rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. For example, a brushless motor with a Kv rating of 3000 powered by a 12V power source would be capable of 36,000 RPMs (multiply 3000×12). This is the max RPMs that this motor can reach under no load.

Are lower Kv motors more efficient?

Lower KV motors have more Kt and are more efficient.

Is KV the same as RPM?

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. The more torque a motor needs to produce, the more current it will draw.

How many turns is a 3300kv motor?

3300 is 13.5 equiv if it were a Novak motor.

Which kV motor for crawler?

There are three options for the motor for the AXE system: 1200 kV is the best choice if you want super slow crawling, 1800 kV for slightly faster crawling and 2300 kV, that was my choice, when you want to be able to drive both slowly and fast.
