PROBLEM TO BE SOLVED: To provide a battery powered inverter for a brushless electric motor that can effectively use a capacity of a battery comprising several battery cells. SOLUTION: The battery powered inverter 1 for the brushless electric motor 2 having a plurality of windings 3a, 3b, 3c, wherein a feeding battery 6 having a plurality of battery cells 8 is connected to a feeding network 4a to a winding via two feeding conductors 5, and at least one second feeding network is connected to the battery 6 via the feeding conductors 5. Preferably, inverter portions 9a, 9b, 9c constituted by a power semiconductor device for the windings 3a, 3b, 3c of the brushless electric motor 2 are respectively arranged in each feeding network 4a, 4b, 4c. Preferably, sensors are provided at each feeding network 4a, 4b, 4c, and the sensors are connected to a control means 14 that controls the inverter 1. COPYRIGHT: (C)2004,JPO
