It is straight to increase input current, output torque is improved, is hindered with overcoming, if however, this situation fails to exclude as early as possible, it will be so that negative
It carries electric current and abnormal raising occurs, and then in current overload condition occurs, the over-current protecting unit 64 of the control device 6 can be felt
Abnormal conditions of the sensing current value (Im) higher than reference current value (Iref) for comparing the output of battery 30 are surveyed, at this point, described
PWM control unit 65 will be reset in time, and stop output pulse wave width modulation signal, and the driving unit 66 also stops output
Pulse wave electric voltage promotes driving motor 4 to rotate, and achievees the purpose that overload protection, and the another display unit 67 receives overcurrent protection
The electric current high levle signal that unit 64 exports, and display component is triggered according to received signal and carries out display current overload feelings
Condition, user can the situation according to display unit 67, get obstacles out of the way, if current overload condition, and overcurrent occurs
Protection location 64 and it is not operating when, also using the overcurrent protection switch 61 execute contact escape de-energizing actions.
Referring to FIG. 1, FIG. 2 and FIG. 3.In the present embodiment, the electric power of battery 30 is gradually consumed, when overvoltage protection list
When the sensing voltage value (Vbbl) of member 63 is lower than reference voltage value (Vref), the Overvoltage protecting unit 63 is the low standard of output voltage
The signal of position at this point, the PWM control unit 65 will be reset in time, and stops output pulse wave width modulation signal, the drive
Moving cell 66 also stops output pulse wave electric voltage and driving motor 4 is promoted to rotate, and to prevent 30 over-discharge of battery, the display is single
Member 67 i.e. receive Overvoltage protecting unit 63 export voltage low level signal, and according to received signal trigger display component into
Row display undertension situation, user can the situation according to display unit 67, battery 30 is removed, and is filled
Electricity, and can reach the purpose for extending 30 service life of battery.
