What do the numbers mean on RC electric motors?

The number of turns indicates how much wire is wrapped inside the motor. … 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.

What do the numbers mean on a brushless motor?

Brushless motors are typically categorized by a four-digit number – such as **##. where as the “**” numbers are the stator width and “##” is the stator height. Essentially, the wider and taller the motor is, the larger the numbers are and the more torque it can produce. KV is another essential parameter.

What does the KV rating on a motor mean?

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. RPM= Kv * Voltage.

What does the number of turns on an RC Motor mean?

Turns. Turns refers to the number of times the copper wire has actually been revolved around the armature. The higher the number of turns greater is the torque generated and hence greater is the power delivered. However that also means less RPM rating for your rc car electric motor.

Does higher KV mean faster motor?

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. … A higher turn number means more wire and thus more resistance, resulting in a slower motor.

Why does a brushless motor have 3 wires?

there are 3 wires because it’s a 3 phase brushless system. at any given time two provide power and the other is a sensor. So even though they may split their time doing each, at a split second in time two provide power and the third is a sensor.

How many turns is a 3300kV motor?

13.5

How long do Brushless RC Motors last?

1,000 to 3,000 hours

How many turns is a 540 motor?

The vxl motor is on par with a 10 turn(540 sized) brushed motor for power output. The 12 turn titan is a 550 motor so the armature is longer than the standard 540 motor(stinger) thus a 12 turn 550 has similar wire resistance as a 15 turn 540 motor as more wire is needed per turn around the armature.

How do I choose an RC motor?

Inrunners run better at higher RPM (2000-10000 RPM/V roughly) and outrunners run better at lower RPM (1000-2000 RPM/V roughly). Inrunners tend to be bigger for lower RPMs than outrunners. You can guess that the first thing you need to decide then is what speed (RPM) you want your motors to run at.

How fast do brushless motors go?

Brushless motors are capable of producing more torque and have a faster peak rotational speed compared to nitro- or gasoline-powered engines. Nitro engines peak at around 46,800 r/min and 2.2 kilowatts (3.0 hp), while a smaller brushless motor can reach 50,000 r/min and 3.7 kilowatts (5.0 hp).

How do you calculate the power of a brushless motor?

Brushless motor calculation

  1. Imax= sqrt(V Io/Rm) Torque at max efficiency: …
  2. Ip= (V + Rm Io)/(2 Rm) Torque at max power output. …
  3. MOTOR MAXIMUM EFFICIENCY: (Better mechanical output to electrical work ratio) η max= [1- Sqrt ( Io Rm / V )²] …
  4. USING THIS EQUATIONS: A device is wanted to be moved through water by means of a propeller arrangement.

What is a 540 size motor?

540 has a diameter of 36mm. 380 has a diameter ~28mm. 280 has a diameter of 24mm. The S, L or XL after the numbers refers to the motor length.
