What is the speed of a motor and power output under the following conditions?
stall torque = 200 oz-in (1.41 N-m)
no load speed = 4000 RPM
applied torque 80 oz-in (0.565 N-m)
speed =
RPM
power =
W
Note: it may be helpful to look at the equation T= T,-aw. You know some information about stall torque and no load speed, that you can use to find the speed at
another torque (T) value
