LINEAR MOTORS
PRODUCT OVERVIEW
Mager full designs high performing voice coil linear motors of VC series .
But what is a voice coil?
It is a brushless linear motor, the name comes from one of its historical first application: vibrating the paper cone of a loudspeaker.
It consists of a permanent magnetic field assembly (permanent magnets and ferrous steel) and a coil assembly. The current flowing through the coil assembly interacts with the permanent magnetic field and generates a force vector perpendicular to the direction of the current. The force vector can be reversed by changing the polarity of current flowing through the coil.
A linear voice coil actuator is ideal for short strokes closed loop servo applications . Its compact size allows it to fit into small spaces. It has very low electrical and mechanical time constants. The low moving mass allows for high accelerations of light payloads .
The result is a much
simpler
and
more reliable system
.
The strenght point is: the voice coil is equipped with a specific drive which, if properly driven, is able to develop a controlled net force while it is chasing a real-time profile movement, without using a force feedback (load cell).
Coupling the actuators with an air bearing system, position feedback device, linear servo amplifier and motion controller yields a system that is capable of handle position, velocity, and acceleration control .
BENEFITS
Mager develops high performing voice coil actuators and selects the best supplier of raw material; we get the best results in terms of:
- Best force-load ratio
