Why do electric machines seem to suffer in performance under cold conditions?
Many electric machines are battery powered. Batteries produce electricity through chemical reactions, which slow down when it is cold, thus reducing power production. Machines, in general, need oil for lubrication.
The Short Answer
Many electric machines are battery powered. Batteries produce electricity through chemical reactions, which slow down when it is cold, thus reducing power production. Machines, in general, need oil for lubrication. When the oil gets cold, it becomes more viscous. This increases drag/friction, and thus reduces the speed or power.
