Ideal for applications where space is limited without compromising on performance.
Moving Magnet Actuator Series
If you are designing a linear motion system, there is a lot to gain by using direct drive voice coil actuators (VCA) technology. Our Moving Magnet Actuator Series shine in applications where precise control is necessary. Whether you’re seeking for a compact actuator or a robust solution for heavy-duty tasks, we have the perfect fit for you.
Available Linear Actuator Solutions
Voice Coil Actuators consist of 2 main components, the coil assembly and the mover assembly. By applying a voltage across the 2-wire connection of the actuator it will move in one direction. Consequently, reversing the polarity of the applied voltage will move the actuator in the opposite direction. Moreover, the generated force is proportional to the current that flows through the coil. This force is almost constant in the specified stroke range of the actuator.
Moving Magnet Voice Coil Actuator
There are two main types of voice coil actuators, moving magnet actuators and moving coil actuators. As the name implies, for moving magnet actuators the coil is fixated and the magnet moves. As for the moving coil actuator, the magnet core is fixed and the coil moves.
Moving Magnet Actuator excels over the traditional actuator with respect to durability, efficiency and achievable stroke length. It also creates a better thermal path as heat is generated on the outside static part. This prevents the coil from overheating, giving it a much higher force density.
FAQ Moving Magnet Voice Coil Actuator
Voice coil actuators (VCA) are single phase linear brushless DC motors that do not require commutation. This makes them very reliable electric motors.”
Voice Coil Actuators consist of 2 main components, the coil assembly and the magnetic mass. By applying a voltage across the 2-wire connection of the actuator it will move in one direction. Consequently, reversing the polarity of the applied voltage will move the actuator in the opposite direction.
Voice coil actuators are very reliable and durable. They can accelerate quickly and then come to a gentle stop at a very precise point. They also have zero mechanical wear, no backlash and very low zeromechanical friction.
There are two main types of voice coil actuators, moving magnet actuators and moving coil actuators. The moving magnet actuator is easier to cool than the moving coil actuators.
