Then, when the positive brush 109 wears to the wear limit, the light receiver 114 receives the light from the light emitter 113 and a current flows. This current is amplified by the transistor 115, and a constant voltage is obtained at the power diode 118. This constant voltage is applied to the astable multivibrator 112, and the astable multivibrator 112 operates at low frequency.

- the key switch 35 is inserted into the key, and the key switch 35 is turned to drive the star (not shown) and the engine is driven.
- a current is supplied from the battery 36 to the field winding 13 via the brush 10 and the slip ring 9, and a magnetic flux is generated.
- This magnetic flux causes the first claw-shaped magnetic pole 22 of the first pole core 20 to be magnetized to the N pole, and the second claw-shaped magnetic pole 23 of the second pole core 21 to be magnetized to the S pole.
- the rotation torque of the engine is transmitted to the shaft 6 via the belt (not shown) and the pulley 4, and the rotor 7 is rotated.
- a rotating magnetic field is applied to the stator winding 16, and an electromotive force is generated in the rotor winding 16.

- Q 1 -Q 23 are transistors, rl—rl 9, R 4 are resistors, C 1 is a capacitor, 51-58 are constant current sources, C 0 M 1, COM 2 Is a voltage comparator.
- the detection terminal 25 Before the wear limit of the brush 10, the detection terminal 25 is not in contact with the coil spring 11. Then, when the brush 10 is at the wear limit, the detection terminal 25 comes into contact with the coil panel 11. At this time, as shown in FIG. 8, the voltage of the detection terminal 25 fluctuates due to the influence of the vehicle's vibration pick-up, J, and the deterioration of the roundness of the pulling 9.
- the voltage of this detection terminal 25 is input to the detection unit 41 via the Q terminal. Inspection When the input voltage to the sensing unit 41 is lower than a predetermined voltage value (threshold: E 0 ), the transistor Q 1 is turned off. As a result, the positive input (potential of A1) of COM1 is smaller than the negative input (potential of A2), and COM1 turns off. That is, transistors Q3 and Q5 are turned off, and transistors Q4 and Q6 are turned on. Then, the transistors Q8 and Q7 turn on, and the output of COM1 (the potential of A3) goes low as shown in Fig. 6. As a result, the transistor Q9 becomes 0FF, and the output of the determination circuit 42 (the potential of A4) becomes HIGH. As a result, transistor Q19 turns on.
- a predetermined voltage value threshold: E 0
- the transistor Q 1 is turned on.
- the positive input (potential of A1) of COM1 becomes larger than the negative input (potential of A2), and COM1 turns ON. That is, transistors Q3 and Q5 are turned on, and transistors Q4 and Q6 are turned off. Therefore, the transistors Q8 and Q7 are turned off, and the output of COM1 (the potential of A3) becomes HIGH as shown in FIG.
- the transistor Q9 turns ON, and the output of the judgment circuit 42 (the potential of A4) becomes LOW.
- the transistor Q19 is turned off.
- COM2 turns off. That is, the transistors Q11 and Q13 are turned on, and the transistors Q12 and Q14 are turned off. Therefore, transistors Q15, Q16 Turns ON, and the output of COM2 (B3 potential) goes LOW. At this time, the transistor Q 18 turns off. At the same time, transistor Q10 is turned off, and charging of capacitor C1 is started. Then, when the potential of the capacitor C1 rises and the positive input (potential of B1) of COM2 becomes larger than the negative input (potential of B2), COM2 turns on.
- the transistor Q19 when the transistor Q19 is in the OFF state, the transistor Q18 is turned ON / OFF, so that the transistor Q23 is turned ON / OFF.

- This blinking of the indicator light 37 is continued until the power supply in the circuit is turned off, that is, until the key switch 35 is turned off. Therefore, when the key switch 35 is OFF, the indicator 37 does not blink, and when the key switch 35 is turned ON again, the indicator 37 resumes blinking. Then, the rider visually recognizes the blinking display of the indicator light 37 to recognize the wear limit of the brush 10. Then, the key switch 35 is turned off to stop the rotation of the engine, the wiring on the negative side of the battery 36 is removed, and the brush 10 is replaced. Then, when the key switch 35 is turned on after the replacement of the brush 10, the blinking display of the indicator light 37 is released because the coil panel 11 and the detection terminal 25 are in a non-contact state.
- the voltage comparator COM1 when the input voltage of the detection unit 41 exceeds the threshold (E 0 ), the voltage comparator COM1 is turned on, and at the same time, the voltage comparator COM1 is turned on.
- the determination circuit 42 is configured to hold the ON state. That is, the determination circuit 42 is configured to maintain the determination result once it determines that the brush 10 has reached the wear limit. Therefore, when the wear limit of the brush 10 is reached, When the electric potential of the detection terminal 25 fluctuates due to the vibration of the vehicle or the deterioration of the roundness of the slip ring 9 when the coil 25 is in contact with the coil spring 11 Does not change, and the detection reliability is improved. Similarly, resistance to external noise is increased, and detection reliability is improved.
- the transistor 29 for turning on or off the indicator light 37 is directly operated by the output from the power generation control device 18, a circuit for operating the transistor 29 is formed in the integrated circuit. As a result, the number of parts can be reduced, which has the effect of reducing costs. Furthermore, since the integrated circuit 30 has a blinking mechanism for the indicator light 37, the number of components can be reduced, and the cost can be reduced.
- the input from the brush wear limit detection unit (light receiving unit 114) is used as the power supply voltage of the display circuit (astable multivibrator 112) of the indicator lamp 106.
- the input fluctuated due to the influence of vibration or the like, and the driving power of the indicator light 106 became insufficient, and it became difficult to confirm the periodic blinking of the indicator light 106.
- the power supply voltage of the transmission circuit 43 for blinking the indicator light 37 is supplied from the battery 36 via a constant voltage circuit, so that the oscillating operation is limited to the brush wear limit. It does not depend on the input from the detector and becomes stable, and the above-mentioned problem does not occur.
- a third control unit 33 for detecting a brush wear limit includes a first control unit 31 for detecting a state of no power generation of the generator, and a second control unit 3 for detecting an overvoltage state of the generator. 2 and the fourth control unit 34 for controlling the output voltage of the generator at a constant level, the integrated circuit 30 is constituted, so that the number of parts can be reduced and the cost can be reduced.
- the brush wear limit is reported by the blinking display of the indicator light 37, and the status of no power generation and overvoltage is reported by the lighted display of the indicator light 37, so that the occupant cannot wear the brush.
- Limits and no power and overvoltage conditions can be easily identified.
- the judgment circuit 42 and the oscillation circuit 43 operate independently. The same effect can be obtained by connecting the output of the COM 1 of the force determination circuit 42 to the oscillation circuit 43 in series.
- the power generation control device 18 having the power generation control function (the fourth control unit 34) and the diagnostic function (the first and second control units 31 and 32) has a brush.
- the function of warning the wear limit (third control unit 33) is described as being added, a function of warning the brush wear limit may be added to the power generation control device having only the power generation control function. Needless to say.
- the vehicle can travel normally for a predetermined distance after the start of the blinking display of the indicator light 37, and the generator can be prevented from being in a no-power-generation state before the brush is replaced.
- the determination circuit 42 determines the brush wear limit based on the voltage of the detection terminal 25, but the determination circuit 42 determines the brush wear limit based on the current flowing through the detection terminal 25.
- the brush wear limit may be determined.
- the brush wear limit detecting unit is described as being configured to detect the wear limit of the brush 10 by contact between the detection terminal 25 and the coil spring 11, The brush wear limit detection unit is not limited to this configuration.
