Q3. A mechanical load has 114.59 Nm. A Dc motor must be selected to support this mechanical load. (a) Calculate the power needed for this torque if the angular velocity, w is equal to 104.72 rad/sec. (3 marks) (b) What is the value of the electrical power equivalent to the mechanical power? (3 marks) (c) Calculate the rotation per minute Nr. (3 marks) (d) Calculate the back emf of the DC motor if the maximum current is 50 A. (4 marks) (e) The motor produces a flux of 13.85 milli-Weber and has four poles. How many parallel paths, c does the motor have if the number of conductors is 1040. (4 marks) (f) What type of winding does this motor have? (4 marks
