Im new to RC (1 year) and wanted to get a brushless system.

In a combo it said the motor has a 1Y winding.
Another said the motor has a 2D winding.

Could someone explain?

Thanks,
Leo

I haven't a clue what that means So apologies

Thanks anyway

the number refers to the amout of turns, the letter refers to the termination, delta or wye. so the "1Y" has one turn, terminated wye.

so this http://www.hobbyking.com/hobbyking/s...520KV_80A.html has a two turn motor? cause someone said in a comment this set has about 11.5 turn

thanks

Turns and kv are not constant. One motor may have 13 turns, one motor may have 2, and they will both have the same KV.

Y and D (Wye (or star) and Delta) are winding configurations. The easy way to remember it is the phrase 'Wye so slow?', because Y windings (typically found in RC motors) are slower than Delta windings but make more startup torque. Delta has less torquey startup and will usually be faster, turn for turn. Delta also draws slightly more current.

Wiki DC electric motor for some additional reading.

thanks to all!!!
