Document Type and Number:
Japanese Patent JP2023131703
Kind Code:
A
Abstract:
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
