Motor, 12 V DC

Advantages: ·         Rotor, coreless ·         High starting torque ·         Low moment of inertia Compact experiment motor – can also be used as a tachogenerator, oscillation generator or for the excitation of rove waves. The motor has a coreless rotor and thus has a high starting torque at a lower moment of inertia. It is characterised […]

Demonstrationsvågsmaskin, enkelmodul

The Demonstration Wave Machine allows for easily visible demonstrations that show the behavior and properties of transverse waves. The motion of the wave is demonstrated by a chain of 73 steel pendulum bars each soldered at their mid-point along a rod spring that can be subjected to torsion. The ends of the bars are painted […]

Demonstrationsvågmaskin, komplett uppsättning

Supplement to the demonstration wave machine comprising a module with short pendulum bars, a transition module and two module couplers. If the two models with differing bar lengths and thus differing wave velocities are coupled together, then reflections can be observed at the point where they are joined together. This can be avoided by adding […]
