Motors should not coast more than a few shaft revolutions after being deenergized. Critical applications use electromechanical clutch and brake devices to stop loads when motor power is removed.

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 ...

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 ...

There are various ways to construct a motor, and the properties of that motor will depend on the construction choice. The series motor configuration has some desirable properties, but it can become ...

THE greater part of this compact little treatise has appeared in the columns of a contemporary. The principles governing the arrangement and proportioning of armature windings are worked out by a ...
