Armored tracklayers with electric drives have many of their merits when compared with me?chanical drive vehicles. It has become an important direction of tracked combat vehicles development. The paper gave a brief introduction as to the status and trends, and lays out the constitution and basic forms of electric drive systems in armored tracklayers. References were given to developments of electric drive sys?tems in cars, giving interrelated achievements abroad. Four kinds of pivotal technology were expounded and some view points for reference were presented.
