Abstract

Due to the development of a high efficient drive train based on a direct drive brushless DC motor (BLDC) powered by a Lithium-Ion battery, STIHL has the possibility to provide professional mobile outdoor power equipment with high output power and sufficient operating time. The requirements of the different products like chain saws, trimmers, blowers, lawn movers or hedge trimmers are very specific due to the different fields of application. Therefore STIHL decided to develop a motor kit specially designed to meet the requirements of all applications but also to be optimized in terms of production cost. This paper describes the development process of the motor kit, which powers the new STIHL rechargeable battery driven products.
