The technology of electric motors for automotive applications is moving toward high rotating speed to enhance the power density of the machine. High-speed operations introduce mechanical constraints on the design of the rotor core that often heavily affect electromagnetic motor performance. These aspects are particularly relevant in the design of synchronous reluctance motors where the rotor shape strongly drives the motor performance. This paper investigates the adoption of carbon fiber sleeves and structural adhesive epoxy resin potting in a simple synchronous reluctance rotor, attempting to analyze the potential benefits and generalize adoption strategies. The investigation will focus on the analyses of the pre-compression, the required thickness of the carbon fiber, and the bonding properties of the epoxy resin.

Abstract
The technology of electric motors for automotive applications is moving toward high rotating speed to enhance the power density of the machine. High-speed operations introduce mechanical constraints on the design of the rotor core that often heavily affect electromagnetic motor performance. These aspects are particularly relevant in the design of synchronous reluctance motors where the rotor shape strongly drives the motor performance. This paper investigates the adoption of carbon fiber sleeves and structural adhesive epoxy resin potting in a simple synchronous reluctance rotor, attempting to analyze the potential benefits and generalize adoption strategies. The investigation will focus on the analyses of the pre-compression, the required thickness of the carbon fiber, and the bonding properties of the epoxy resin.Pubblicazioni consigliate
