MOTOR CONTROL DEVICE FOR ELECTRIC FARM WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To suppress battery consumption in a two-motor type electric farm working vehicle including separately an electric motor for power that generates traveling power and working power, and an electric motor for a hydraulic pump that drives the hydraulic pump.

SOLUTION: An electric riding rice transplanter includes a planting working machine 3 liftably connected to a traveling machine body 1; a working machine lifting hydraulic cylinder 4 lifting the planting working machine 3; the hydraulic pump 15 supplying pressure oil to the working machine lifting hydraulic cylinder 4; the electric motor 5B for the hydraulic pump that drives the hydraulic pump 15; the electric motor 5A for power that generates traveling power and working power; and a motor control device 23 controlling driving of the electric motor 5A for power and the electric motor 5B for the hydraulic pump. The motor control device 23 detects the lifting operation fixed state of the planting working machine 3, and stops driving of the electric motor 5B for the hydraulic pump when the planting working machine 3 is in the lifting operation fixed state.
