Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. … 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 does 12T mean on RC Motors?
A 12T double would use two wires wound twelve times and a 12T single a single thicker wire wound twelve times around each rotor pole. A low turn single will be best for HIGH RPM and a higher turn triple or quad have higher TORQUE over its RPM range.
What are turns on an electric motor?
Inside an electric motor, permanent magnets are set onto a ring surrounding a coil of wire. When the appliance’s switch is flicked on, electrons flow through the wire, turning it into an electromagnet. The attractive and repulsive forces of the permanent magnets around it make the electromagnet spin.
What does the T mean on brushed motors?
The higher the kV rating the faster the R.P.M of the motor. The lower the turns, the higher the R.P.M. of the motor. 3.5T means 10,500 RPM. 4.5T means 9,000 RPM.
Does lower KV mean more torque?
Kv allows you to get a handle on the torque that can be expected from a particular motor. Torque is determined by the number of winds on the armature and the strength of the magnets. 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.
How can a motor spin fast?
One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.
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.
Does the motor rotate continuously when there is current?
Because the current flows in opposite directions in the wires, Fleming’s Left-Hand Rule tells us the two wires will move in opposite directions. … If the coil of wire could carry on moving like this, it would rotate continuously—and we’d be well on the way to making an electric motor.
What’s the best RC crawler motor?
The 55t TorqueMaster 540 Expert motor for crawling is our best suggestion. It is not overly powerful on 2 or 3s LiPo and is less likely to break parts. Faster (lower) turn counts, Pro series brushed motors, and brushless motors can break parts more easily.
How many turns is a 3300kv motor?
3300 is 13.5 equiv if it were a Novak motor.
What does a 12 turn motor mean?
A 12 turn motor will be tons faster and will drain a battery faster . Just as he said. a twelve turn motor will have more RPM, less torque, and draw more current. The number or turns refers toi the number of times the wire is warpped around your armature in the motor.
How many amps does an RC motor draw?
Around 60-80 amps.
