Tsurumi’s Operation, Service, and Repair Manual

(c)The engine, starter, and control wiring exits through a hole in the side of the control box. The diode and fuse that are part of the DC circuit are located inside the control box.

(d)The generator leads and control wiring are connected inside the control box. A flexible rubber sleeve provides protection for the generator wiring.

B.FUNCTIONAL DESCRIPTION

(1)Generation of No-Load Voltage (refer to Figure 3)

(a)When the generator rotor begins to rotate, the permanent magnet in the rotor gener- ates 3 to 6 volts alternating current in the main coil and in the condenser coil windings.

(b)The low voltage generated in the condenser coil also generates minute current flow (a) through the condenser coil. At the same time, low-level magnetic flux intensifies at the rotor’s magnetic pole. As the magnetic force intensifies, voltage increases in the main coil and in the condenser coil. As current (a) increases, magnetic flux also increases at the rotor’s magnetic pole, and continues to increase as generator speed increases.

(c)As AC current flows through the condenser coil, the density of the magnetic flux in the rotor changes. The change in magnetic flux density induces AC voltage in the field coil, and the diode rectifier in the field coil circuit rectifies the AC voltage into DC voltage. The resultant DC current flows (b) through the field coil and magnetizes the rotor core to generate output voltage in the main coil.

(d)When the generator speed reaches 3000 to 3300 rpm (60 Hz generators), the current in the condenser coil increases rapidly. This acts to stabilize the output voltage of each coil. When the generator speed reaches its rated speed, the generator output will be at its rated value.

(2)Voltage Fluctuations Under Load (refer to Figure 3)

(a)When output current (c) flows through the main coil to the appliance being used, a magnetic flux is produced and serves to increase current (a) in the condenser coil. As a result, the current flowing in the field coil increases and the generator output voltage is prevented from decreasing.
