Description

Start motor of low temperature resistant engine Technical Field The utility model relates to the technical field of starting motors, in particular to a starting motor of a low-temperature-resistant engine. Background It is well known that starting of an engine requires support by external forces, and that a starter motor plays this role. In general, the starter motor implements the entire starting process in three parts. The direct current electric motor draws in current from the battery and produces mechanical movement of the drive gear of the starter motor. The starter motor is used for starting the engine, and after the engine is started, in order to prevent the starter motor from being damaged due to dragging of the high rotation speed of the engine, the starter motor is disconnected from the engine and is in a stop state, but at a lower temperature, the lubricating oil and sealing components in the starter motor are easy to fail, so that the starter motor is damaged, and therefore, the starter motor suitable for the low temperature resistant engine is required.
