QS273 Re-Winding, Looking for someone in UK

[Reecew89]

Just curious as QS Motora said i need a higher T count for torque which i understand but i have enough power to send to generate torque i need well i thought anyway.

It is very rare for those who speak English to have much technical knowledge.

Achieving your desired top rpm later in your throttle range helps with efficiency,

and higher voltages are a bit better for acceleration, but less efficient at low speeds

in general, when you change the winding, you ONLY change what ratio of voltage to amperes are needed to make a certain amount of power.

Thanks for the reply much appreciated.

So same question i asked above,

I am curious if i can push enough power before damaging the motor to get my desired torque failing that ill buy another motor ie a 4t or 5t?.

Theoretically, and it's a hot topic on this forum, you can get the same torque from any number of turns, you just have to apply more amps in inverse ratio to the turns.

The torque is limited by the area and radius of the air gap between magnet and stator and the number of ampxturns.

Fewer turns=more copper per turn fits so the possible amp x turns remains the same. Overall, there is no change.

However, you might end up needing a controller that handles an impractically large number of amps, and rather thick phase wires.

I generally have come to favour more volts, insulation is cheaper than copper and circuit boards tend to burn because of over current melting traces not over voltage arcing between them.

Well done!
