Linear motors are increasingly used in industrial applications to replace drive devices with easily worn mechanical transmission components. They can provide high speed and acceleration, good adjustment accuracy and accurate positioning. No intermediate elements for torque conversion machines are required.
The application of linear Motors is very wide, including medical technology, optics, electronics, textile industry, machinery manufacturing, loading and unloading transportation and packaging industry. Some mechanical requirements in machining are particularly high. The use of linear motors can meet its performance and increase acceleration. The linear motor must achieve the fixed acceleration and put forward a high requirement for the mechanical structure of the linear guide rail. The linear motor will produce a high axial force during operation. The guide device absorbs the 300N force that appears. Therefore, in the application of high dynamic operation, light weight, high rigidity and strong mechanical guidance devices are required. The guide rails used by linear Motors together with other factors play a joint decisive role in the performance and quality of linear Motors.
The linear motor is also required to have a long service life. The linear guide rail is required to be able to run more than 20,000 km. Expensive maintenance and repair costs arising from downtime due to replacement of components or recalibration are not allowed. The guidance system may be operated with less maintenance or without maintenance and cleanly throughout its service life. During the operation, due to high temperature and high dynamics, spills of lubricants and any impurities can not be allowed. There must be better coordination and coordination between the long life and maintenance cycle.
The mechanical efficiency of direct-driven linear systems is much higher than that of rotary driven systems. In a linear motor system, the only necessary mechanical part is a linear guide rail. Therefore, the quality of the part to be moved by the guide device should be kept as small as possible. In addition, the reason why the quality of the linear guide rail is small is that the moving quality will have a direct impact on the adjustment of the linear motor. The requirements for linear guides are: high positioning accuracy, no maintenance, long service life, low operating noise, small rail quality, high acceleration and speed, and so on. In addition, its economy is also better.
Tongmao linear motor adopts European and American technical standards and production processes. The motor structure is simple, small in size, stable in force characteristics, easy to control, and compatible with various brand motion controllers and drives.
