What do the numbers on ESC mean?
The motors are rated by how many amps they can handle safely. So your motor is rated at 20 amps. You use a wattmeter to pick a prop that the motor will handle without going over the 20 amp draw. The ESC needs to be over the rating of the motor by at least 20%, so the 30 amp would work fine.
What does a higher amp ESC do?
Having a higher amp-rated ESC simply means your ESC will be less stressed and run cooler! You always want your ESC to only run at ~80% of rated max.
How do I calibrate my Hobbywing ESC?
Push the throttle trigger to the full brake position, press the SET button, the GREEN LED blinks 3 times and the motor beeps 3 times to accept the full brake endpoint. The motor can be started 3 seconds after the ESC/Radio calibration is complete. The Green LED flashes once and motor emits “Beep” tone.
How do I read my brushless motor specs?
Decoding A Standard Brushless Motor 2204: Represents the dimensions of the motor case and splits into 2 parts; the first two numbers are diameter; the last 2 numbers are height. This number may be in the middle of other letters and model numbers but is easily distinguished as 4 separate numbers.
Is higher amp ESC better?
A high amp esc will usually have better internals than a lower amp esc. Keep tthe questions coming, you do not learn without asking! Amp rating generally means you can run a more aggressive motor (mod motors) with higher amperage. For example, the Hobbywing Justock is just a 45a ESC.
What amp ESC should I use?
If you are using 30amps ESCs, you should choose motors that are bigger than 2205 or faster than 2300kv, and propellers should be bigger than 5 inches. For examples 30 amps is required for the 2204 2700kv, 2204 3200kv, 2205 2700kv or 2206 1900kv(with 6 inch propellers).
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.
