BEI Kimco Magnetics’ new Moving Magnet Voice Coil Actuator Series allows for precise positioning to meet high accuracy requirements. When combined with smart drive electronics, this actuator can be controlled for speed and desired output force. Kimco’s expertise in design of magnetic field circuits has resulted in a high efficiency design which translates to high performance for precision applications. By keeping the magnet mass low, the system inertia is well controlled resulting in more precise speed and position control.
Moving magnet actuators lend themselves to applications that require moderate speed and controllable, gentle stop points, functions not achievable with solenoids or standard voice coil actuators. Typical applications include remotely controlled circuit breakers, medical hand tools and other delicate instrumentation.
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. In addition, having a stationary coil allows for a simpler design of the electrical connections.
