Static charge elimination method and static charge eliminator

A static charge elimination method for neutralizing static electricity on an armature of a rotating electrical machine comprising:

• a first step of placing a first contact in contact with a core of the armature, the first contact being connected to ground;
• a second step of placing a second contact in contact with a metallic section of one of power wires electrically connecting with the coil, the second contact being connected to ground;
• a third step of placing a third contact in contact with outer layers of portions of the wire segments constituting a first coil end protruding from slots formed in the core outside a first end that is one of axially opposed ends of the core, the third contact being connected to ground;
• and
• a fourth step of placing a fourth contact in contact with a resin-molded member wrapping the wire segments constituting a second coil end protruding from slots formed in the core outside a second end of the core axially opposed to the first end of the core, the fourth contact being connected to ground, wherein
• the first step, the second step, the third step, and the fourth step are performed simultaneously.

A static charge eliminator for neutralizing static electricity on an armature of a rotating electrical machine comprising:

• a first contact which is contactable with a core of the armature and connected to ground;
• a second contact which is contactable with a metallic section of one of wire segments constituting a coil of the armature or a metallic section of one of power wires electrically connecting with the coil, the second contact being connected to ground;
• a third contact which is contactable with at least one of outer layers of portions of the wire segments constituting a first coil end protruding from slots formed in the core outside a first end that is one of axially opposed ends of the core, the third contact being connected to ground;
• and
• a drive unit which works to move at least one of the first contact, the second contact, the third contact, and the armature to simultaneously achieve contacts between the core and the first contact, between the metallic section of one of the wire segments or the metallic section of one of the power wires and the second contact, and between the outer layer of the portions of the wire segments and the third contact.
