Drive device for unmanned carrier and unmanned carrier equipped with same

摘要

Even if one of the drive wheels fails, the unmanned carrier is moved in a predetermined direction at a predetermined speed.The drive devices 11 to 14 are connected to a vehicle body of an unmanned carrier via a common fixed shaft 31 to 34, and have wheels 20a and 20b having a common central axis, and outer rotor motors 21a and 21b disposed at an inner diameter portion of wheels 20a and 20b, respectively Inverter circuits 22a and 22b for driving outer rotor motors 21a and 21b are provided.When the inverter circuit 22a or the outer rotor type motor 21a fails, the wheel 20b is rotated by using the inverter circuit 22b and the outer rotor type motor The unmanned carrier can be moved in a predetermined direction at a predetermined speed.Diagram
