Linear Actuator With Moving Magnet Provides Superior Heat Dissipation

Unlike standard voice coil actuators where the magnet assembly is intended to remain fixed while the coil assembly moves, BEI Kimco's Moving Magnet Voice Coil Actuators are designed to use a stationary coil, explains Jim McNamara, Senior Applications Engineer.

When compared to conventional moving coil designs, a fixed coil assembly is more easily integrated with an appropriate heat sink, providing higher continuous duty performance. This is especially important for demanding applications where heat management is of particular concern.

Thanks to Kimco's expertise in design of magnetic field circuits this actuator uses magnetic fields very efficiently. And with Kimco's engineering expertise, it can be customized to meet specific requirements.

In addition, having a stationary coil allows for a simpler design of the electrical connections. Typical applications include remotely controlled circuit breakers, medical hand tools and other delicate instrumentation.
