| -5- Contd. a certain value. 2. The voltage regulation allows the lamps and other apparatus to be operated by the dynamo only, so that, even if the accumulator fail altogether, the lighting is still available. The curves given in Fig. 7 show how effective the voltage regulation is on widely different lamp loads without an accumulator in circuit. 3. The output of the dynamo is automatically increased when a heavy load comes on the system, thus guarding against the accumulator becoming discharged. 4. The location of the voltage regulator and cut-outs, on the dynamo itself, greatly simplifies the wiring. The "Bleriot-Phi" Dynamo is made in two sizes, the output data of which are given below. Type. Volts. Output. Cutting-in speed. E.3 12. 200 watts. 700. r.p.m. C.4.L. 12. 150 " 470 r.p.m. The Type C.4.L is specially suitable for driving in tandem with the magneto on 6-cylinder engines. The height of the spindle centre is in all cases 45 m/m.{Mr Moon / Mr Moore} The Starter. This is a separate machine and is a simple series wound motor built in a tubular yoke. See Fig. 8. The gear engaging mechanism is of the usual bendix type which is so largely used. The armature is mounted on plain bearings as the machine is in use for such short periods that lubrication presents no Contd. | ||
