“…Water flows through the cooling jacket and the heat generated by the permanent magnet linear synchronous motor is taken away by the cooling water. Many studies on the cooling system and thermal analysis have been carried out for permanent magnet motors [3,[5][6][7][8]. However, analysis of the influence of the cooling system on the PMLSM has received less attention.…”

Abstract:In this paper, a novel ironless linear synchronous motor with a cooling system is proposed. Firstly, the topology of this ironless linear synchronous motor with a cooling system is introduced. Flux density in the cooling system is obtained analytically by the separation of variables method according to the boundary conditions. The eddy current braking force induced by the cooling system is calculated and validated by finite element method. Then, the influence of the motor parameters on the eddy current braking force is investigated. At last, a prototype is manufactured and some experiments are carried out with the prototype. The experiment results are validated by finite element analyzed results.

“…5 and if we consider the case where all the losses are located at the inner radius of the winding, it gives an elevation of the temperature in the machine Δθ equal to 8 • C only. This value is obtained with a thickness of 0.1 mm for the insulation and a winding replaced by an equivalent homogeneous material (copper, enamel, and resin) of thermal conductivity assumed here equal to 2 W/m·K with a slot fill factor equal to 0.4 [21], [22]. With geometrical data r s = 0.44 and r w = 0.73 (see Section III), it gives a total thermal resistance equal to 1.4 W/m 2 ·K.…”

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.
