| description | To suppress the reduction in power density by subdividing an operation pattern and optimizing the threshold temperature for overheat protection in a motor overheat protection device.SOLUTION: A speed acquisition unit 8 acquires a motor rotation speed. A temperature acquisition unit 7 acquires a temperature detection value of a motor 1. A threshold change unit 10 sets a threshold temperature on the basis of the motor rotation speed and a motor output. A comparison unit 11 compares the temperature detection value with the threshold temperature. An output control unit 12 stops the supply of electricity to the motor 1 or reduces the motor output when the temperature detection value exceeds the threshold temperature.SELECTED DRAWING: Figure 1
【課題】モータの過熱保護装置において、運転パターンを細分化し過熱保護の閾値温度を最適化することによって出力密度の低下を抑制する。【解決手段】速度取得部８が、モータ回転数を取得する。温度取得部７が、モータ１の温度検出値を取得する。閾値変更部１０が、モータ回転数とモータ出力に基づいて閾値温度を設定する。比較部１１が、温度検出値と閾値温度を比較する。出力制御部１２が、温度検出値が閾値温度を超過したときに、モータ１への通電を停止する、またはモータ出力を低減させる。【選択図】図１ |
