A DC motor has the following parameters: K₁ K₁-0.2 N-m/A, c-5x10 N-m-s/rad, R.-0.8ohm. (a) Assuming steady-state response, obtain the expressions for the no-load speed, the no-load current, and the stall torque. (Assume v, is a variable with unknown value). (b) The datasheet states that the motor's maximum speed is 3500rpm and the maximum current is 40A. Determine if the motor can be used with an applied voltage of v, 15V.

Question
A DC motor has the following parameters: K₁-K-0.2 N-m/A, c=5x104 N-m-s/rad, R,-0.8ohm.
(a) Assuming steady-state response, obtain the expressions for the no-load speed, the no-load current, and the stall
torque. (Assume v, is a variable with unknown value).
(b) The datasheet states that the motor's maximum speed is 3500rpm and the maximum current is 40A. Determine if the
motor can be used with an applied voltage of v. 15V.
