Torque in a motor is a function of field flux and conductor flux. How can conduc- tor flux be increased? A motor is used to convert electrical energy to mechanical energy. True or false? Can the right-hand rule be used to determine the direction of lines of force?

and the armature current 14.5 A. calculate the following: a) The number of conductors on the armature b) The value of the counter-emf at full load c) The flux per pole, in milliwebers [mWb] The following details are given: 73 mm 115 mm 20 40 Armature diameter: armature length: armature slots Image Word A 1.5 hp Permanent magnet motor generates a voltage of 90 V when the motor runs at 2900 r/min. commutator bars: turns per coil: Armature resistance at 20°C: 0.34 2. on P I Sign Extract Text I Share 1/1 More

A 4 pole lap wound dc machine has 728 active conductors running at 1800 rpm. The flux per pole is 30mWb, The armature current is 120 A, What is the electromagnetic power developed in the armature?
