Piezo linear motors with are ultrasonic drives that are designed to produce high frequency oscillations. The movement is created by these motors through the use of a ceramic plate with a friction point that goes along the linear course. This friction point drives the part to move forward and backwards in a linear motion. The oscillation component provides energy for the driving force. It also helps to increase or reduce the pressure against the friction point. The core motor can be a Synchronous Motor (Synchronmotor), and would not include spindles or any gears, there is no chance of any incidents including hysteresis or backlashes.
These motors are equipped with various features allowing for use in multiple applications
• Consolidated Design: The size of the motor can be designed to be compact as no gears are used by linear motors. While providing power and the strength to support the motion that is linear motor periods are of little sizes.These motors are made to attain high speed velocities. Additionally they includea step-and-step characteristic, enabling them to quit within milliseconds. As there are not any screws or lubricants used, there aren’t any limits to acceleration or deceleration.
• Precision Fixtures: Due to this feature, customers don’t need to purchase independent interlocks or light drapes for safety functions.Piezo motors are available in many different industrial and scientific applications including microscopy, metrology, and semiconductor testing equipment, micromanipulation, and biotechnology.
Advantages of Piezo Linear Motors
The utilization of motors can provide industries like the ones mentioned above with quite a few advantages.
• Efficiency: These drives depend on the industry, the motors can be customized by makers with open or closed loop linear motor stages. A particular vehicle lock attribute also can be provided without causing any unnecessary shifting in the part position to create a braking force.
• Firmness:Holding forces can be created by the ceramic stator of the linear motor phases when the motor is at rest. This really is executed by pressing on the stator against the slider. This results without any excessive heat dissipation in an excellent amount of equilibrium.
Integration: The piezo linear motor drives(the core being also available as a DC Motor, or Gleichstrommotor) can be easily incorporated into any industrial application. Pulsed operation can be performed for uses that demand an assortment of motions, from modest measures to high speed moves. Greatest results happen to be found when the motor is kept on a flat surface and in a dry environment. The precision and speed of piezo linear motorsmakes them a superb choice for precision motion uses in high profile sectors.
