Title: Improvements in or relating to electromagnets for voltage regulating apparatus
IPC: H02P9/22
Filed: 1929-09-13
Abstract: 339,947. Potter, E., (Pintsch Akt.-Ges., J.). Sept. 13, 1929. Electromagnets.-In voltage regulating apparatus wherein the frictional and other forces to be overcome by the operating magnet decrease as the attraction stroke proceeds, an electromagnet is employed the torque or pull of which decreases through the working stroke. To give the magnet such a characteristic the air space between the armature and core is made a minimum and the main air gap is located at some other point in the magnetic circuit. The invention is particularly applicable to carbon pile regulators, in the usual arrangement of which the carbon is compressed by a spring acting in opposition to the electromagnet. In the form shown, E is the main air gap of the electromagnet of a carbon pile voltage regulator, and the gap between the armature D and pole-pieces C is made as small as possible. With this arrangement it is stated that the increase of flux per unit of distance traversed by the armatureduring the attraction stroke decreases the more the ends of the armature overlap the polepieces C, and since the pull of the magnet is proportional to the variation of the flux, the torque on the armature is greater at the commencement than at the end of the stroke. The spring (not shown) acting in opposition to the magnet is so arranged that its effective force varies during the attraction stroke just as the magnet pull and reaction of the carbon column. vary.
