The present invention relates to an eco-friendly electric cultivator using a hybrid switched reluctance (HBSR) dual motor and, more particularly, to an eco-friendly electric cultivator using an HBSR dual motor, the eco-friendly electric cultivator being capable of replacing operations performed by existing power cultivators by applying a HBSR dual motor having high torque, efficiency and output instead of a brushless DC (BLDC) motor that has been used in conventional motor related machinery. In an agricultural cultivator including a frame(10) to one side of which a running unit(20) is coupled, and to other side of which an operating unit(30) is coupled, a driving power generating unit which is coupled between the running unit(20) and the operating unit(30), and a handle(50) which has an adjusting lever(51) and is coupled to the running unit(20). The driving power generating unit includes a power supply unit and a driving motor which adopts an HBSR motor. The driving motor is a dual motor consisting of a first driving motor and a second driving motor. The first and second driving motors include first and second driving shafts, and first and second driving gears connected to the first and second driving shafts. A main driving gear(430) which is engaged with the first and second driving gears is positioned between the first and second driving gears by a main driving shaft. The main driving shaft is connected to the running unit(20) and the operating unit(30) by a power transmission unit. The power supply unit includes a BMS(Battery Management System), and a cable which connects a battery pack(451) and a driving motor. The BMS transmits respective charging information of plural sub-packs which form the battery pack to an ECU such that the ECU determines charging orders and charging amounts of the sub-packs. The ECU charges electricity in the battery pack(451) by stopping driving of the second driving motor based on the charging information of the BMS, thereby enabling the second driving motor to generate electricity according to driving of the first driving motor. |
