Product Description

Alumina ceramic components / relay ceramic assemblies / ceramic - metal brazed contactor

 

1. Description:

The control behaviour of an electro-dynamic motor, also known as a moving coil motor, is superior to other motor types. This is also true for the linear version of this motor type. The classic solution to produce an xy movement with a long-stroke is to apply a stack of at least two linear motors. A rising moving mass, combined with a limited mechanical stiffness, limits the bandwidth. An alternative is the planar motor, which generates x- and y-movements. This paper describes an electro-dynamic planar motor with moving coils, which levitates and propels itself over long x- and y-strokes under full control over six degrees of freedom (6-DOF).

13Guiding questions for material selection:

In order to select the appropriate material for your application, there are several questions that you should consider.

1) Are the mechanical properties important?

2) Will the part be exposed to wear/friction/impacts?

3) How many pieces are you looking to have made in your first batch?

4) What type of atmosphere will the part be operating in; inert or oxidizing?

5) What is the maximum operating temperature of the component?

6) Will the component experience any thermal shock?

7) Is electrical insulation important?

8) Is thermal conductivity important?

9) How important are tolerances and surface finish?
