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.

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.

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.

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.

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

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.

Linear electromagnetic actuators with solenoid type, are widely used in industrial applications. They are part of various electromagnetic devices based on different controlling mechanisms;

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.
