In this paper, a novel methodology is presented in order to design a permanent magnet synchronous machine associated with a gearbox for a screwdriver application. The study shows how, from specification such as maximum volume, maximum heating, torque, and speed profiles, it is possible to formulate the sizing problem. The modeling is based on a purely analytical formulation. We will show that it is possible to establish rules in order to make optimal choices of materials (magnets and stator core). The optimization of the pole pair number and the choice of the gear ratio will also be discussed. Finally, the finite element method will be used to validate the designed machine.Index Terms-Analytical models, design methodology, energy efficiency, frequency conversion, high-speed permanent magnet synchronous motor, machine tool, magnetic losses, soft magnetic materials.

“…H IGH-SPEED brushless permanent magnet (PM) motors have been widely used in many industry applications such as machine tools, compressors, vacuum pumps, and friction welding units due to their high efficiency and power density, small size, and low weight [1]- [3]. There are several possible PM motor designs for high-speed operations: 2-pole [1]- [4], [6]- [8] or 4-pole [5], [9]; 3-slot [1], [4], [6] or 6-slot [5], [9]; overlapping [2], [3], [5] or nonoverlapping [1], [5], [9] windings; slotted [1]- [9] or slotless [6]- [8] stators; and rotors with [3], [9] or without [1], [2], [4]- [8] a sleeve retaining the surface-mounted magnets.…”

This paper deals with the optimal design of surface-mounted permanent magnet motors for use in a high speed spindle machine tool in glass grinding applications. We apply the Taguchi method to refine the stator structure and use segmented rotor magnets for the motor to yield the desired performance. A thermal analysis is conducted to obtain the temperature distribution within the motor. We examine the results using finite element analysis and validate them by experimental measurements.Index Terms-Efficiency, finite element analysis (FEA), surface-mounted permanent magnet (SPM) motor, Taguchi method, torque ripple.

This paper shows that the split ratio of the stator inner diameter to the outer diameter has an influence on the airgap flux density, stator copper loss, thermal load, torque density and cost for interior permanent magnet synchronous motors (IPMSMs) applied in electric vehicles (EVs). This paper presents a simplified analytical method to study the optimization of the split ratio considering both the efficiency and cost. The validity of this method is verified by experiment on a 35kW prototype.Index Terms-Electric vehicles (EVs), interior permanent magnet synchronous motors (IPMSMs), split ratio, stator copper loss, thermal load.
