That is, if the set duty ratio is not 80% or more, the duty ratio setting is repeatedly executed according to the trigger signal TG input from the trigger switch 28.

- the determination criterion regarding the duty ratio is not limited to 80% or more as in the present embodiment, and may be appropriately set according to the configuration of the electric power tool 10. This is a value stored in advance in the duty ratio setting unit 154 as a threshold value.
- the duty ratio setting unit 154 confirms the time measured by the timer 156.
- step S50 the process proceeds to step S50, and if the first predetermined time T1 is not exceeded, the process returns to step S10.
- the determination criterion of the first predetermined time T1 or more is stored in advance in the duty ratio setting unit 154 as the time when the motor 32 is estimated to be stopped.
- the first predetermined time T1 can be set to about several tens of milliseconds, for example. That is, in step S40, the duty ratio setting unit 154 determines whether or not the motor 32 is stopped. If it is determined that the motor 32 is stopped, the process proceeds to step S50.
- the duty ratio setting unit 154 reduces the duty ratio set to 80% or more to 70%. Accordingly, as shown in FIG. 7, the ON signals UH, VH, and WH to the upper arm side switching elements 111 to 113 are changed to pulse signal trains by pulse width modulation.

- the range in which the duty ratio is lowered is in the range of 10% to 50%.
- the upper arm side switching elements 111-113 in the case of FIG. 7, two upper arm side switching elements 111 112 will remain on for a long time. If this state continues, the bootstrap capacitors 131a-133a continue to discharge, and the voltage of the bootstrap capacitors 131a-133a decreases.
- the voltage drop of the bootstrap capacitors 131a to 133a due to such discharge is not limited to the case where the duty ratio is set to 100%, but can occur when the duty ratio is set to a relatively high value of 80% or more.
- the voltage of the bootstrap capacitors 131a-133a decreases, it becomes impossible to apply a sufficient drive voltage to the upper arm side switching elements 111-113. In this case, the on-resistance of the upper arm side switching element 111-113 may rapidly increase, and the upper arm side switching element 111-113 may burn out due to its own heat generation.
- the duty ratio is decreased at the time (P2) when it is determined that the motor 32 is stopped, and the arm side switching elements 111-113 are intermittently turned off, the bootstrap capacitors 131a-133a are charged, That voltage will be maintained. Thereby, burning of the upper arm side switching elements 111-113 can be prevented.
- step S60 the duty ratio setting unit 154 confirms the time measured by the timer 156. If the time measured by the timer 156 is equal to or longer than the first predetermined time T1, the process proceeds to step S70. If the time does not exceed the first predetermined time T1, the process returns to step S10. Also in step S ⁇ b> 70, the duty ratio setting unit 154 confirms the time measured by the timer 156. If the time measured by the timer 156 is equal to or longer than the second predetermined time T2, the process proceeds to step S80, and if the second predetermined time T2 is not exceeded, the process returns to step S60. Here, the second predetermined time T2 is set longer than the first predetermined time T1.
- the duty ratio setting unit 154 determines whether the motor 32 is still stopped or whether the motor 32 has started to rotate again. When the time measured by the timer 156 is equal to or longer than the second predetermined time T2 (Yes in the process of step S70), it is determined that the motor 32 is still stopped. In this case, the duty ratio setting unit 154 proceeds to the process of step S80, and sets the duty ratio to zero percent. As a result, as shown in FIG. 7, the operation of the motor 32 is forcibly terminated at the time point P3 when the second predetermined time T2 has elapsed from the time point P1.
- step S60 when the time measured by the timer 156 is less than the first predetermined time T1 (Yes in the process of step S60), it is determined that the motor 32 has started to rotate again.
- the duty ratio setting unit 154 returns to the process of step S10.
- the duty ratio according to the trigger signal TG is set again at the time point P4 before the time point P3. For example, if the user continues to operate the trigger switch 28 to the maximum, the duty ratio is reset to 100%. If the motor 32 is only temporarily locked by overload or the like, the user can continue the operation without operating the trigger switch 28 again.
- the upper arm side switching is performed even when the trigger switch 28 is operated to the maximum.
- Elements 111-113 are turned off intermittently. Since the upper arm side switching elements 111-113 are intermittently turned off, a voltage drop due to the discharge of the bootstrap capacitors 131a-133a is prevented, and a sufficient drive voltage is continuously applied to the upper arm side switching elements 111-113. . This prevents the upper arm side switching elements 111-113 from being burned out.

次に、ステップS20において、デューティ比設定部154は、入力したトリガ信号TGに基づいてデューティ比を設定する。
次に、ステップS30において、デューティ比設定部154は、設定したデューティ比が80パーセント以上であればステップS40の処理に進み、設定したデューティ比が80パーセント以上でなければステップS10の処理に戻る。即ち、設定したデューティ比が80パーセント以上でなければ、トリガスイッチ28から入力されるトリガ信号TGに応じて、デューティ比の設定を繰り返し実行する。ここで、80パーセント以上というデューティ比に関する判定基準は、上アーム側スイッチング素子111-113の焼損が起こり得るデューティ比の範囲として、デューティ比設定部154に予め記憶されたものである。デューティ比に関する判定基準は、本実施例のような80パーセント以上に限定されるものではなく、電動工具10の構成に応じて適宜設定するとよい。
閾値として予めデューティ比設定部154に記憶されている値である。
一方、ステップS40の処理に進んだ場合、デューティ比設定部154は、タイマ156による計時時間を確認する。そして、タイマ156による計時時間が第1所定時間T1以上であればステップS50の処理に進み、第1所定時間T1を超えていなければステップS10の処理に戻る。ここで、第1所定時間T1以上という判定基準は、モータ32が停止していると推定される時間として、デューティ比設定部154に予め記憶されたものである。第1所定時間T1は、例えば数十ミリ秒程度に設定することができる。即ち、このステップS40では、デューティ比設定部154により、モータ32が停止しているのか否かが判断される。そして、モータ32が停止していると判断された場合、ステップS50の処理に進む。
ここで、ステップS50の処理でデューティ比を低下させる幅は、10パーセントに限定されない。モータの出力を無用に低下させ過ぎることなく、ブートストラップコンデンサの放電による電圧低下を防止することができる範囲であればよく、具体的には10パーセントから50パーセントの範囲で設定するとよい。
また、電動ドライバ10のような電動工具では、モータの出力が低下したことが、利用者によって直ちに感受される。そのことから、ステップS50の処理でデューティ比を低下させることによって、モータ32への負荷が過大であることを利用者に報知することが可能となる。ただし、デューティ比を大きく低下させすぎると、電動ドライバ10からの反力が急激に低下することから、利用者がバランスを崩すといったことも起こりえる。これらの観点からも、デューティ比を低下させる幅は、10パーセントから50パーセントの範囲とすることが好ましい。
タイマ156による計時時間が第2所定時間T2以上となった場合(ステップS70の処理でイエス)、モータ32は依然として停止していると判断される。この場合、デューティ比設定部154はステップS80の処理に進み、デューティ比をゼロパーセントに設定する。それにより、図7に示すように、時点P1から第2所定時間T2が経過した時点P3において、モータ32の運転を強制的に終了する。
本明細書または図面に説明した技術要素は、単独であるいは各種の組合せによって技術的有用性を発揮するものであり、出願時の請求項に記載の組合せに限定されるものではない。本明細書または図面に例示した技術は複数の目的を同時に達成するものであり、そのうちの一つの目的を達成すること自体で技術的有用性を持つものである。
