Abstract: This paper introduces flywheel energy storage system (FESS) with particular focus on motors and controllers. The paper covers the principle and characteristics of permanent magnet brushless DC motors, permanent magnet synchronous motors, induction motors and switched reluctance motors, which are usually used in flywheel energy storage system. Various control strategies associated with the four types of motors are discussed. Advantages and disadvantages of the motors and their control strategies are analyzed.

Key words: flywheel energy storage system, motor generator set, control strategies
