The practical testing of dynamos and motors (1905)
Smith, Charles Frederick, 1873- · Manchester Scientific Pub. Co · leaf 96
U fall,and this wiU reduce the pressure sending current throughthe magnet windings. The exciting current and strengthof field will therefore also be reduced. Since the strength SHUNT-WOUND DYNAMO. 81 of field does not increase regularly in proportion to theampere-turns on the magnets, the voltage… … D Dynamo armature. F Dynamo field windings. R Adjustable resistance for regulating the load. A Ammeter for measuring load current. V Voltmeter for measuring dynamo voltage. S Switch for breaking main circuit. • Connections.—Connect the shunt winding to thearmature terminals, so as to render the…
