Question: 1a mechanical load is driven by an electric motor at...

Question details

1)A mechanical load is driven by an electric motor at an equilibrium speed Wa.

The load is Tl = 20+0.6w and the load moment of inertia is Jl= 2kgm^2

The speed-torque relation of the motor is w=100-0.1T and the moment of inertia

is Jm = 0.2 kgm^2.

a) Calculate the power requirement for Wc operation speed

b) Calculate the stopping time of the motor when its turned off at the

continuous operating W

c)Draw torque-speed characteristics of motor and load in the same graphic.

d)Comment on the stability of the operating system
