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 ...

No extant markings. A radial armature with five permanent magnets is mounted above a cylindrical electromagnet that is covered with black painted cloth. The armature axis is perpendicular to the axis ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
