The motor shown in Fig. 19 was designed by Mr. William Hochhausen to regulate and to keep a constant speed with a variable load, with fixed brushes and without the interposition of external resistance. It has a single magnetic circuit, in which the armature is included. The regulation is effected by varying the intensity of the magnetic field to correspond with the load. For this purpose the field coils are divided into ten sections, the ends of which are brought to consecutive strips, shown at the side of and below the armature. The governor is of the centrifugal type, and acts upon an armature which extends downwardly and operates upon a contact maker which touches the various contact strips to which the field coils are connected. As the speed changes, these sections are cut in or out, varying the magnetic strength of the field accordingly. |
