Double Sided Linear Induction Motor


-Introduction of double side linear Induction motor:

 

With the development of logistics and the improvement of automation, logistics transmission systems are becoming more popular in various of industries. Take the example of double sided linear induction motor, it is the new trend of advanced and innovative logistics transmission technology.

 

 

On the other hand, using the linear motor is a trend of advanced logistics transmission technology such as the cross belt sorter motor in logistic industry. The structure of the linear motor mainly includes three parts that are the stator, the mover and the support wheel for linear motion. In order to ensure the linear induction motor's electromagnetic field coupling between the stator and the mover is in the range of travel, the iron core length of stator and mover are not equal. The sorter motor's stator can be made as two formations which are short stator and long stator.

The linear induction motor is a transmission device that directly converts electrical energy into linear motion by expanding a closed magnetic field into an open magnetic field without any intermediate conversion mechanism. This kind of cross belt sorter motor is actually a rotating electric machine that is sectioned by radial direction and developed into plane. The corresponding part of the stator is primary level, the rotor’s part is secondary level. The multi-phase alternating current in the primary level produces a traveling wave magnetic field. The driving force of linear motor is generated under action of the travelling wave magnetic field and the secondary permanent magnet to realize the linear movement.

 

 

The linear motor is easy to support the mover with magnetic suspension so that the mover and stator always maintain a certain air gap without contact which eliminates the contact friction resistance between the stator and the mover. Except for that, this type of cross belt linear motor can realize non-contact transmission of force that the mechanical friction loss is almost zero.

-Advantages of double sided linear induction motor:

 

 

1.The linear motor has no mechanical friction during operation and will not cause loss of mechanical parts that does not need complicated maintenance.

 

2.The linear induction motor has low noise and wide speed range, it is suitable for the full speed range from 0.8 meters per second up to 3 meters per second. This sorter motor will not slip under low temperature environment.

 

3.The structure of this cross belt linear motor is simple. According to the linear motor does not need an additional device to change the rotary motion to the linear motion, it's weight and volume are greatly reduced with simplified structure.

 

4.This cross belt linear motor has high positioning accuracy because of it can realize direct transmission without errors caused by intermediate links.

 

5.The cross belt sorter motor has fast response and high sensitivity. It is safe and reliable for operating with long life time.
