Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

Technology at present needs faster and easier means of controlling equipment with few numbers of components. One of such equipment is the Direct Current (DC) motor, whose speed is directly ...

A compound motor operates at a speed of 1,520 rpm when the voltage impressed across the armature terminals is 230. If the flux per pole is 620,000 Maxwells and the armature resistance is 0.43 ohm, ...
