Elliptec Motor X15G
The operation of the Elliptec Motor X15G is based on the inverse piezoelectric effect.
A microcontroller and two tiny transistors are all that is needed to supply the piezoelectric ceramics with a sufficient electric voltage to cause the ceramics to expand by less than one micrometer and to let it contract again when the voltage is turned off. During motor operation, this interplay occurs about 100’000 times per second.
The form of the resonator strengthens the vibrations of the piezoelectric ceramic and transformed them into elliptical motions at the motor tip.
A spring maintains a steady pressure between the resonator tip (aka the stator) and a driven element (aka the rotor), which in turn is moved by up to a few micrometers with every oscillation of the piezoelectric element. As this process occurs at supersonic frequencies, the motion of the driven element is continuous and smooth.
Not only is the Elliptec Motor the right choice for simple applications such as for the actuation of protective lids or locks, the Elliptec Motor also satisfies the demand for motions of the highest precision with fast reaction speeds in adverse environmental conditions, and also for other specialized requirements. Many applications can utilize the standard model X15G, but customer specific motors can be manufactured on demand where necessary.
