Question 1

T = mw + b

Given that the Stall Torque is php0Gwi89.png. This is the maximum torque generated by the motor. This occurs when the speed is zero.

So when w =0,T=T

Substituting this, we get

T. = mx 0+ b


Now the no load speed is phpXhoXTu.png. This is the speed when there is no torque.

So when phpOQ91eD.pngphpTcWQSo.png, “ო = ო

Substituting this we get

0= mxm + b

m = - wm

m = - wm

Hence we can write

T = mw + b

r- :+T,

So the characteristic Torque – Speed equation is

r- :+T,

In the specification, we can see that

T = 2.97 oz - in

wm = 6200 RPM


T = 2.97 T=-6200 6200 +2.97

T = -0.000479w+ 2.97

Question (2)

Speed (RPM) 100 200 300 400 500 600 700 800 900 1000 1100 1200 Torque (oz - in) Power (Watts) 2.97 0 2.9221 0.2162354 2.8742
