How many poles on outrunner

This decreased resistance would allow a greater current load to pass through the motor. When comparing a 4 Pole motor that has the same physical size as a 2 Pole motor and the same KV as a 2 Pole motor, the 4 Pole motor in theory would be able to handle greater current loads. The greater current loads will result in greater power.

This is similar to saying a 4 pole motor has better overall efficiency when compared to a 2 pole motor. Although it sounds like there are many advantages, there are also some down falls to this as well. It is very common for 4 pole motors to not have as many motor options as a similar 2 pole motor. Less motor options may make it difficult to get the exact KV value you need. This is even with 4 pole motors using both wind types. A wind type is the difference in how a wind is terminated before it gets to the 3 wires hanging out the brushless motor that you typically see.

These wind types are commonly known as the Delta wind and the Wye wind. Using one wind type over another does provide different motor characteristics yet again. We will note this as a possible disadvantage as well. Overall, it will come down to testing, testing, and testing.

There may be many reasons to this including your driving habits. In order to determine which works best for you, it is recommended to give both types a try. You may prefer either one of them.

I understand the chart above. Charles Cowie Charles Cowie Is the number of pole-pair of a bldc motor and pole-pair per phase are same? Physically is it possible to see a pole pair? What about the north and south poles in the inner peripherals of the rotor? Can you justify Mr. Charles Cowie formula counting the number of starter windings in the answer?

Charles Cowie. Please tell me it is true or false? Yes or no, please!!! Show 3 more comments. Dave Tweed k 16 16 gold badges silver badges bronze badges. Jim Z.
