The increase in the demand of linear motors is principally driven by the replacement of traditional mechanical (ball screws, gear trains, cams), hydraulic, or pneumatic linear motion systems in manufacturing processes with direct electromechanical drives. Linear motors are also used in various applications such as high-speed maglev transport and elevator hoisting.

Synchronous generators are the most popular energy converter to generate electrical energy from mechanical energy [1]. Although they are widely used at different power stations, they can also be found in transportation applications such as aircraft and ships. In this application note, a typical synchronous generator used in an aircraft electrical system is studied under different load conditions. Its performance is investigated using the finite element method (FEM) tool in EMWorks 2D software.

Permanent magnet brushless DC motors (PMBLDC) are used in a wide range of applications thanks to their high-power density and ease of control. In particular, outer runner PMBLDC is utilized in direct drive wind turbines and small electric vehicles such as golf cars and electric bikes to mitigate the need for mechanical transmission or gearboxes. This can improve the efficiency of the whole system which results in a longer battery lifetime

Magnetic levitation is a method by which an object is suspended in the air with no support other than magnetic fields. The fields are used to reverse or counteract the gravitational pull and any other counter accelerations. It is a highly advanced technology and has various uses. The common point in all applications is the lack of contact and thus no wear and friction. This increases efficiency, reduces maintenance costs, and increases the product lifespan.

Eddy current brakes are based on the braking torques (forces) generated by induced Eddy Currents inside an electrical conductor by electromagnetic induction. Stationary electric conductor immerged inside a time-varying magnetic flux and/ or a moving electrical conductor inside a static magnetic flux will lead to the creation of eddy currents in this conductor.

Electric motors are becoming increasingly used in industrial applications. They offer a high efficiency, high power factor and a wide speed range. The spoke type motor is one of the common electric motor types presented in the market today. Spoke type motors use a compact permanent magnets structure, arranged in spokes for a better torque generation [1]. With the adequate material selection, the spoke type motors have the highest torque density architecture among the permanent magnet motor types, provided they are cost-effectively manufactured and especially effectively cooled [1].

Linear actuators have many applications ranging from domestic to industrial. Their role consists of converting many forms of energy such as electrical energy, hydraulic energy etc to a mechanical linear motion.

Magnetic gears (MG) which achieve contactless power transmission are increasingly attracting the interest of industry. Traditional mechanical gears suffer from several weaknesses: friction losses, lubrication issues, heat, vibration and noise. Magnetic gears are therefore developed to overcome the issues accompanying the use of traditional mechanical ones.

A switched reluctance motor (SRM) is a rotating electric machine where both stator and rotor have salient poles (Figure 1). The stator winding comprises a set of coils, each of which is wound on one pole.

Electromagnetic actuators are electromechanical components used to convert electrical power to a mechanical motion. they cover translational and rotational motion. DC actuators are generally composed of permanent magnets, solenoids and ferromagnetic parts.

EMWorks2D

Magnetic actuators use electromagnetic fields to convert electrical energy into mechanical energy. Depending on the motion whether it is translation or rotation, actuators are classified on two main categories which are linear and rotary actuators.
