torque vs rpm relationship in Electric Motor Driven Machines

Great Video Terry, great to know that you can reduce or increase the torque with gearing.

Great video 👌

Two bike torq 8.05 @ 5000rpm and 8.05 @ 6000rpm batter bike issss????

thank you sir keep up the good work.

Smart.

tks for sharing .. great video ..cheers

i rewind my DC motor with more Thicker Winding coil, it became faster, the RPM increased more. But when i place remote car on the ground, it can't carry the Car, almost not moving it can't carry the load. it can fast but the Torque of the DC motor drops almost zero

When talking about 3 phase induction motors this is not accurate. When there is slip from the electromagnetic Flux and the rotor there will be an increase in torque. Rpm goes up and so does torque.

Why is it not in metric?

Good explanation. But we people(other than USA) use Meter, Kilograms.

Great video.
Thanks for sharing Mister.

I need to understand one thing because i have a little confusing about torque and speed and the performance on the motor .
The torque is how much rotation power applied on the motor shaft to rotate around its axes.
when i look at a motor curve i see inverse relation between torque and speed. But i want to know if the motor speed goes up and torque goes down , is it good or not good for motor efficiency and performance ? i mean if the speed increased the torques decreases too but what does that mean for the motor efficiency good or not ? if the torque lowers by speed means the load is not heavy and a little current motor consumes ? if torques increases and speed decreases that means more current motor consumes ?

Why does the torque go down, is it because of centrifugal force?

Terry you are a delightful teacher

Watched several videos on this subject of which all left me confused your video has let a blind man see thank you.

Wow! I now understand.
Thank you, sir!

The neep for speep

Best explanation I've seen for this subject!
