Linear motor is a mechanical energy that converts electrical energy directly into linear motion by opening a closed magnetic field into an open magnetic field without the need for any intermediate conversion mechanism. Its structure can be seen as a rotating motor cut down along the radial direction, and the circumference of the motor extended into a straight line formed. The stator is equivalent to the primary of the linear motor, and the rotor is equivalent to the secondary of the linear motor. When the primary is connected to the current, a traveling wave magnetic field is generated in the air gap between the primary and secondary, and the driving force is generated under the action of the wave magnetic field and the secondary permanent magnet. In order to achieve the linear motion of the moving parts.
In the feed system, the difference between the direct drive of a linear motor and the original rotary motor drive is that the mechanical transmission link between the motor and the workbench(drag board) is eliminated, and the length of the feed drive chain is shortened to zero. Therefore, this transmission method is also called &;; Quot; Zero Drive & amp; Quot; And ... It's because of this &; Quot; Zero Drive & amp; Quot; In this way, the performance indexes and advantages of the original rotary motor driving mode can not be achieved. At present, the linear motor on the market is mainly divided into iron core, no iron core and no slot linear motor.
We provide U-type non-core AC brushless linear motor, provide standard tracks, travel can be extended, can be made into a single-axis platform system, multi-axis system, customers can directly install equipment. It can also be customized according to the needs of customers.
Its main features are:
High response, low noise, no maintenance, smooth thrust characteristics, extended stroke
The acceleration is large, the speed is fast, the acceleration and deceleration process is short, and the application of the grid ruler can also achieve higher accuracy.
