PROBLEM TO BE SOLVED: To provide a motor which operates stably for a long time, preventing electrolytic corrosion. SOLUTION: Since electric charge generated on a shaft 2 is caused to flee to an anti-load side bracket 5a directly, and is not discharged into roller bearings 3, electrolytic corrosion is prevented. Since contact is caused to occur at a part where a peripheral speed is slow, suppression of a mechanical loss becomes feasible.
