How do you calculate ESC size?
To arrive at the size of ESC you need, when you know how many cells in series, divide the maximum wattage of your chosen motor by the voltage of your power pack. This will give you the current (amps) that your ESC will have to handle.
What size ESC should I use?
The ESC can be selected based on the voltage and the peak current rating of the motor. A simple rule is to choose an ESC with atleast 5A more capacity than the peak rating of the motor, since you may be powering servos, receiver and other accessories from the ESC.
Why did my ESC catch fire?
Simply Bad ESC Badly designed or over-rated ESCs are likely to catch fire. You probably don’t want to push the limit with these ESCs.
What’s the maximum current a lipo ESC motor can draw?
For a 20C battery with 5000mAh capcaity, the maximum current that can be drawn is 20*5000 = 100000mA = 100Ampere. Chose a battery with higher current rating than the peak current draw of the motor.
What kind of battery do I need for my ESC?
Your ESC is rated for operation at 6-12V, which suggests that you could use a 7.4V or 11.1V Lipo battery. Battery capacity and ‘C’ rate should match the expected current draw and run time. For example if the average current draw is 15A and you want to get 10 minutes then you need at least 15*(10/60) = 2.5Ah or 2500mAh.
How to calculate the maximum capacity of a space?
Square footage of the use divided by the “Occupant Load Factor” = maximum capacity. Then divide by 2 to determine 50% of maximum capacity per the Governor’s emergency order Example 1: Retail store showroom with 2,000 sf is divided by 60 sf (from the chart) = 33 max
What happens if ESC voltage is higher than motor voltage?
Maximum voltage of ESC should not be higher than what the motor can suffer. Current in ESC is larger than motor. If the discharge current cannot reach the required value of ESC, then the ESC won’t work on its highest performance. Moreover it will cause battery temperature raise then explode.
