Discrete sub-system due to passive elements in motor drive require functional and structural integration to make efficient and power dense overall system. Such power dense system is the prerequisite in aerospace and marine applications. This paper presents the design optimization of integrated rotor-less inductors for high speed AC drive applications. Different slot-pole combinations are considered...
This paper considers the design and analysis of a tubular linear permanent magnet machine for high force density applications, such as in the aerospace industry. Different machine topologies and slot-pole combinations are considered. Optimization with respect to machine geometry is addressed analytically and validated through finite element simulations. A technique to reduce heat build-up in the winding...
This paper looks at the design of a high speed permanent magnet synchronous machine for maximum power density. Machines with sub-unity slots per pole per phase are characterised by low cogging torque, high slot fill and short end windings which contribute to lower copper losses. However such machine topologies tend to have a harmonic-rich armature reaction field which may contribute significantly...
