With the rapid development of various industries in China's industrial field, the quality of products produced is required to be higher and higher, and the requirements for machine performance, speed, and accuracy are gradually increasing, especially in CNC machine tools, semiconductor integrated equipment and other machinery. For obvious. The original “rotating motor + ball screw” feed transmission method that dominates has gradually been unable to meet the higher requirements of ultra-high-speed cutting and ultra-precision machining in terms of feed speed, acceleration, and rapid positioning accuracy. The rapid growth of linear motors.

Drive motor, also known as DD motor, directly converts electrical energy into linear motion mechanical energy. It has large starting thrust and high transmission rigidity. Application industries such as processing equipment continue to put forward higher requirements for processing quality and efficiency. High-speed and high-precision processing equipment such as machine tools, 3C electronics, semiconductor equipment, and laser processing equipment have become the main market for linear motors. Take the LED die bonder driven by a linear motor as an example, because of its fast speed, high acceleration, and high positioning accuracy, it is favored by middle and high-end customers in the market.

With the development of technology, the performance of linear motors continues to improve, and the cost is declining, creating conditions for its wide range of applications, and application industries such as processing equipment continue to put forward higher requirements for processing quality and efficiency. High-speed and high-precision processing equipment such as machine tools, 3C electronics, semiconductor equipment, and laser processing equipment have become the main market for linear motors.

In addition, linear motors have applications in robotics, lithium batteries, EMS, electronics manufacturing, textile machinery, packaging machinery and other industries. In the future, with the deepening of intelligent manufacturing and industrial automation, the market scale of linear motors will gradually increase.

Why do we use Rexroth linear motors

1: The fast speed and strong acceleration can maximize the processing efficiency, and at the same time can withstand frequent fast movements.

2: Good control performance and positioning accuracy, the grating ruler feedbacks the real position (full closed loop). The encoder feedback of the servo motor is the theoretical position (semi-closed loop)

3: Direct power transmission, no mechanical transmission components (such as ball screw, timing belt, rack and pinion, etc.), while reducing energy consumption, reducing the links that may cause errors, and avoiding mechanical errors, such as screw transmission There is bound to be a return gap.

4: The movement process of the motor realizes the non-contact transmission of force. The mechanical friction loss is almost zero, there are few failures, maintenance-free, and long service life.

5: Xiangju Industry-has been at the forefront of drive technology development
