How do I choose a quadcopter motor?
The one rule of thumb for choosing your motors – ideally, your drone should be able to hover in midair at about half throttle. This means that when you choose the apt motor for your drone, it should be able to produce 50% more thrust than the multirotor.
Is a higher Kv motor better?
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. So turns with a lower number means a faster motor.
How to choose motor and propeller for quadcopter?
You need to arrive at the right balance in terms of RPM and torque when choosing a motor and propeller for your drone. When you attach bulkier propellers with motors with high values of KV, the motor will attempt to rotate the propeller fast resulting in drawing more current and producing more heat in the process.
How to calculate the thrust of a quadcopter?
So at 50% throttle the total thrust produced by it should be 150 Kg with a per motor total thrust of 37.5 kg. I have looked at this answer to How to calculate quadcopter lift capabilities? but don’t understand how to use this information to work out the specifications of motor and propeller required for my application.
How to calculate quadcopter lift capabilities, Stack Exchange?
If you use a 3S LiPo battery, your battery may drop done to 9.6V, so, if you want to keep your dynamic during the whole flight, you shall choose a motor that may reach the rpm target at 9.6V. Let’s say you need 10k rpm to get your TWR=2, your motor’s Kv shall be at least 1040 rpm/V.
How does a different payload affect a quadcopter?
Flying with a different payload will have an effect on the control, flight and balance of the drone. A different payload will then require different quadcopter motor thrust. If you are building your own or designing quadcopters, then understanding motor and propeller design is essential information.
