Abstract
Description
より具体的には、実際の運転状態を模擬すべく、電動モータとダイナモメータとの間に生じるトルクを測定し、この測定値に基づいて必要な負荷などを判断して、ダイナモメータを制御するようにしている。
さらにその際、芯出し等にミスアライメントが生じると、その影響でコギングトルクを正確に測定することができないという問題も生じ得る。
ここで、例えば、電動モータとダイナモメータとを接続するシャフトにコギングトルク測定用モータを接続する場合、この接続箇所にかさ歯車などを用いる必要がある。一方、上述した構成であれば、コギングトルク測定用モータをダイナモメータに簡易な構成で接続することができる。
この場合、上述したようにかさ歯車などを用いる必要はあるが、電動モータ試験システムを設置するスペースが、電動モータやダイナモメータの回転軸方向に限られている場合には有利である。
これならば、トルクセンサにより測定される測定トルクが、コギングトルク測定用モータの回転が電動モータに伝達されている状態では、コギングトルクとして測定され、ダイナモメータの回転が電動モータに伝達されている状態では、電動モータの性能試験に用いられる通常試験用トルクとして測定される。つまり、トルクセンサをコギングトルクの測定と通常試験用トルクの測定とに兼用することができ、コギングトルクを測定するための専用のトルクセンサは不要である。
これならば、コギングトルク測定用モータは高速で回転すると破損する恐れがあるところ、通常試験時に、コギングトルク測定用モータをダイナモメータから切り離すことで、ダイナモメータの高速な回転をコギングトルク測定用モータに伝わらないようにすることができ、コギングトルク測定用モータの破損を防ぐことができる。
これならば、コギングトルク測定用モータに必要とされる低回転性能における回転安定性を向上させることができる。
200・・・電動モータ
10 ・・・ダイナモメータ
20 ・・・接続機構
300・・・回転伝達系
30 ・・・トルクセンサ
50 ・・・コギングトルク測定用モータ
60 ・・・接離機構
なお、本実施形態では、電動モータ200及びダイナモメータ10は、例えば床や台X上に載置されて固定されている。
具体的にこのダイナモメータ10は、例えば、図示しない交流モータたる電動モータを備えた交流式電気動力計であり、本実施形態では、図1に示すように、回転軸11の一端側11a及び他端側11bから動力を出力できるように構成された両端駆動式のものである。
なお、トルクセンサ30としては、例えば接触式或いは非接触式など、種々のタイプのものを用いても構わない。
なお、コギングトルク測定用モータ50は、電動モータ200の回転軸201を角度制御するものであっても良い。この場合、コギングトルク測定用モータ50としては、前記回転軸201を所定角度回転させる回転状態と、前記回転軸201を所定時間停止させる停止状態とを交互に繰り返すように構成されたものが挙げられる。
上述した配置により、接離機構60は、ダイナモメータ10と減速機70との間に設けられることになり、コギングトルク測定用モータ50とともに減速機70を回転伝達系300に接続する又は切り離すことができる。
通常試験時は、接離機構60が制御装置40からの制御信号を受け付けて非接続状態となり、コギングトルク測定用モータ50を回転伝達系300から切り離す。なお、このとき、コギングトルク測定用モータの電源はオフにしておくことが好ましい。
この非接続状態において、トルクセンサ30は、電動モータ200とダイナモメータ10との間に生じるトルクを測定し、この測定トルクを示す測定信号を制御装置40に出力する。
制御装置40は、前記測定信号が示すトルクを通常試験トルクとして取得し、前記通常試験トルクに基づいて、ダイナモメータ10を制御して駆動装置或いは負荷装置として機能させる。
これにより電動モータ200を所定の運転試験状態にして、該電動モータ200の動作性能を試験することができる。
コギングトルク測定時は、接離機構60が制御装置40からの制御信号を受け付けて接続状態となり、コギングトルク測定用モータ50を回転伝達系300に接続する。
この接続状態において、ダイナモメータ10を無負荷状態にすることにより、該ダイナモメータ10はフリーになっており、コギングトルク測定用モータ50が電動モータ200を低速度で回転させる。
このとき、トルクセンサ30は、コギングトルク測定用モータ50が電動モータ200を回転させることにより発生するトルクを測定し、この測定トルクを示す測定信号を制御装置40に出力する。
これにより、制御装置40は、前記測定信号が示すトルクを電動モータ200のコギングトルクとして取得することができる。
そのうえ、電動モータ200の性能を試験する通常試験時は、コギングトルク測定用モータ50を回転伝達系300から切り離すことで、ダイナモメータ10の回転がコギングトルク測定用モータ50に伝わらず、コギングトルク測定用モータ50が高速で回転して破損することを防ぐことができる。
具体的には、接離機構60が、図2に示すように、例えばかさ歯車80等を介して、接続機構20(具体的には、シャフト)に接続される構成が挙げられる。
この場合、接続機構20に設けられたトルクセンサ30は、接続機構20と接離機構60との接続箇所より、電動モータ200側に位置していれば良い。
なお、上述した実施態様は、図2に示す電動モータ試験システム100に関しても同様に適用することができる。
