To provide a crushed stone generation system which performs precise inverter control of an IPM motor according to a crushing state of a stone material while utilizing performance of the high-performance IPM at a maximum to increase efficiency of generation of crushed stones.SOLUTION: A crushed stone generation system 1 for crushing a stone material to generate crushed stones includes: crushing teeth 19 which crush the stone material; an IPM motor 14 which drives the crushing teeth 19; a lithium-ion battery 13 which supplies electric power to the IPM motor 14 and absorbs regenerative energy from the IPM motor 14 to be charged; and an inverter 15 which controls operation of the IPM motor 14. The inverter 15 controls the operation of the IPM motor 14 according to a state of the stone material during crushing. The state of the stone material during crushing is acquired from a state detection sensor 16 as necessary.SELECTED DRAWING: Figure 1 【課題】高性能なＩＰＭモータの性能を最大限に活かしつつ、当該ＩＰＭモータを石材の破砕状態に応じて詳細にインバータ制御することで砕石の生成を効率化する砕石生成システムを提供する。【解決手段】石材を破砕して砕石を生成する砕石生成システム１において、石材を破砕する破砕歯１９と、破砕歯１９を駆動するＩＰＭモータ１４と、ＩＰＭモータ１４に電力を供給すると共に、当該ＩＰＭモータ１４からの回生エネルギーを吸収して充電するリチウムイオンバッテリ１３と、ＩＰＭモータ１４の動作を制御するインバータ１５とを備え、インバータ１５が、石材の破砕中の状態に応じてＩＰＭモータ１４の動作を制御する。石材の破砕中の状態は、必要に応じて状態検知センサ１６から取得される。【選択図】図１
