Title:
電動作業機
Document Type and Number:
Japanese Patent JP6673347
Kind Code:
B2
Abstract:
Provided is an electrical working machine allowing control of low-speed rotation to be easily achieved compared to prior art. Any one of a plurality of different types of storage batteries with mutually different rated output voltages can be selectively mounted in a self-propelled lawn mower 1. A drive power source circuit 17 is a DC-DC converter capable of at least stepping down the voltage, and outputs the voltage by converting the output voltage of the storage battery 30 to a stable direct voltage of 18 V. The output voltage of the drive power source circuit 17 is supplied to a control power source circuit 14 via a back flow preventing diode D2 and is also supplied to a left-wheel driver 18, a right-wheel driver 19 and a cutting blade driver 20.
