Multi-physics modeling of MicroElectro-Mechanical-Systems using EMS for SOLIDWORKS

EMS

In this application note, a PM magnet axial flux generator is studied under load and no-load conditions. To perform this analysis we used EMS coupled with SOLIDWORKS Motion

The heat generated by the coil is one of the major design aspects of a DC linear actuator. In addition to significantly shortening the life expectancy of its mechanical components, the temperature changes can affect the actuator’s efficiency and repeatability.

EMS

Crosslinked Polyethylene (XLPE) is extensively used as an electrical insulating material in Power cables for underground distribution and subsea transmission. It is gradually replacing the typical low-density Polyethylene in such applications, because of its excellent insulation characteristics (high dielectric strength, low dielectric permittivity and loss factor) and its great mechanical and thermal stabilities. XLPE come to be used on a large-scale voltage transmission for more than 200kV.

A voice coil actuator is analyzed using EMS inside SOLIDWORKS. Static simulation are performed to calculate Lorentz force results versus different positions and current rates. Electromechanical simulation using EMS coupled to SOLIDWORKS Motion are both used to compute linear displacement, speed and acceleration,etc.

EMS

Lorentz force of a voice actuator is computed versus different voltage rates. Electrothermal simulation is use to calculate the temperature evolution caused by winding losses of the actuator.

EMS

A voice coil actuator, based on the Lorentz force concept, is a type of direct drive mechanism which delivers extremely precise positioning over small displacements. The voice coil is currently used for wide range of applications.

Eddy current coupler is a non-contact coupling system that works on the Eddy current principle, where a circular electrical current is induced within a conductor by a nearby varying magnetic field.

EMS

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.

Permanent Magnet couplings (or couplers) are used to transmit torque from a primary driver to a secondary follower without any mechanical contact. Many industrial applications are based on such transmission system that doesn`t need any external electrical circuit for motors and propellers. They are especially used for high security applications and in sealed equipment for transmissions through walls.

In this article, rotary eddy currents brakes (ECB) will be studied. Typical braking systems (hydraulic, pneumatic, mechanic) employed in most engines, are designed to slow or halt the motion of vehicle by converting kinematic energy to heat energy by friction.

3D FEM simulation of a T-Shaped electromagnetic actuator was performed, and the results are discussed in this article

EMS

Magnetic actuators are based on electromagnetic field to convert electrical energy into mechanical energy. Depending on the type of generated motion; linear or rotational movement, electromagnetic actuators are classified in two categories: rotary and linear actuator.

EMS

Renewable energy, known also as green or clean energy, is derived from natural processes that are regenerative over short periods of time and cannot be depleted.
