PURPOSE: To eliminate a malfunction such as a conduction between commutator segments by forming the atmosphere of mono-(polyoxyalkylene) ether of alkane diol in a motor case.
CONSTITUTION: An atmosphere of 6∼24C mono(polyoxyalkylene) ether of alkane diol is formed in a small-sized motor case of the structure that a brush mechanism and a commutator are provided and brushes are slidably contacted with a commutator. Examples of the 6∼24C mono(polyoxyalkylene) ether of alkane diol include an additive of 1mol of ethylene oxide of hexyleneglycol, an additive of 1mol of propylene oxide, an additive of 2mol of ethylene oxide, an additive of 2mol of propylene oxide, an additive of 4mol of propylene oxide and 2mol of ethylene oxide, an additive of 1mol of propylene oxide.
