Servo shutter mechanism uses voice coil drive

Geeplus product story

A voice coil drive, which enables much faster open/close speeds to be achieved, is the heart of a new servo shutter mechanism developed by Geeplus Europe.
A voice coil drive - instead of the more usual solenoid or geared motor mechanism - which enables much faster open/close speeds to be achieved, is the heart of a new servo shutter mechanism developed by Geeplus Europe.
The direct drive of the control rig allows the device to fully open or close in less than 5ms.
Although this speed is achievable using a solenoid, only an open/close function is obtained, whereas a geared device cannot cannot get anywhere near these speeds.
If a positional encoder is incorporated within the shutter device, it can be partially opened at speed to any position, enabling it to create the function of any iris.
The first version developed by Geeplus has a 36mm aperture, but the company says that both smaller or larger versions can be produced.
Using processes and technology which allows even small quantities to be produced economically, Geeplus say that their device has increased reliability due to less wear.
The use of positioning sensors allows the shutter blades to be started or stopped at the end of every process without the use of a mechanical stop.

Geeplus launches smallest voice coil motor
Geeplus International has launched a standard voice coil motor that measures 16mm in diameter, 14mm in length and develops 0.55N of force. -
Solenoid offers increased stability
The use of an electrically driven permanent magnet rotor in the Geeplus' new solenoid provides fully energised torque which is available for the fastest rotation in either direction. -
Easy connection for voice coil motor
The VM2836 voice coil motor includes a flex circuit termination and cover to provide a simple and reliable electrical connection. -
Electromagnets reject residual magnetism
Electromagnets are designed with ejector pins to enable them to overcome the problems of residual magnetism occurring when power to the device is switched off. -
Voice coil motor takes a new slant
A very low profile flat voice coil motor from Geeplus Europe is designed in such a way that it offers good clearance in assembly and has latitude for tilting on one axis.
