DC Linear Actuator

DC LINEAR ACTUATORS

Direct Drive Electric Actuator

Voice coil actuators (VCA) are single phase linear brushless DC motors that do not require commutation, making it a very reliable electric motor. They allow for easily controllable movement, suitable for high-end industrial equipment and high duty cycle applications. Our linear actuators can simultaneously achieve high precision, fast acceleration and high speed over a defined stroke. Making it the ideal motor for engineers who want precise, repeatable and controllable linear motion for their applicatio

If you are designing a linear motion system, there is a lot to gain by using direct drive linear actuators technology. Our actuators shine in applications where precise control is necessary. Because our moving magnet linear actuators consist of a stationary coil and a moving permanent magnet assembly, they can create more stroke and force in a compact package

Direct Drive Linear ACTUATOR: RELIABLE AND DURABLE

A key advantage of a moving magnet linear actuator is that they are very reliable and durable. This is, in comparison to moving coil Actuators, due to the lack of moving wires. Compared to other electric actuators motors with gearboxes, they can accelerate quickly and then come to a gentle stop at a very precise point. In addition, tour dc linear actuators are compact and have zero mechanical wear, no backlash and very low zeromechanical friction.

Fast Linear Actuator series

The design of the fast linear moving magnet actuators have been proven in various high-end industrial equipment. Magnetic Innovations has developed multiple series of direct drive dc linear actuators.

1) Frameless voice coil actuators –  MI-MMA series.
2) Voice coil actuators with integrated slide bearing – MI-MMB series.
3) Motor controller, compatible with the MMA and MMB Moving Magnet VCA series.

MI-MMA Linear Actuator series (Frameless)

The most cost effective type of DC Linear Actuators is our frameless voice coil actuator. Frameless means that the bearing is not provided with the linear actuator. This allows engineers to optimise their design and embed the motor in a way that is best suited for their application. These actuators are also applicable in applications in a vacuum environment. With a frameless linear actuator you can count on a motor with high speed, high force density, high reliability and a long lifetime.

The MMA Serie consist out of the MMA 1525, MMA 1555, MMA 3070, MMA 5536 and the MMA 9054.

MI-MMB Linear Actuator series (with integrated slide bearing)

This is our most complete actuator, it comes with an integrated bearing systems. With this dc linear actuator, engineers are not required to add their own alignment system. This can make it easier to integrate the motor into their application. The linear actuator can support high positioning resolutions -in combination with external position sensors and motion controllers. They enable reduced system cost, control complexity and improve robustness

The MMB Serie consist out of the MMB 1525, MMB 1555, MMB 3070, MMB 5536 and the MMB 9054.
