Modular direct drive rotary motor
The cartridge ddr motor is a new direct drive solution that consists of a unique bearingless housing and integrated rotor, stator and high resolution feedback device that is aligned at the factory. The application of the cylindrical ddr technology eliminates mechanical transmission components, retaining all the advantages of direct drive and avoiding the complex and expensive drawbacks of conventional closed or frameless ddr solutions. The modular direct drive rotary motor utilizes a novel compression coupling to connect the rotor to the shaft and comes with a unique collet design that enables “out of the box” and takes less than 30 minutes .
The advantages of modular technology, along with its significant reduction in competitive price and total life cost, will accelerate the application of direct drive technology in new machine designs in many areas such as smelting, packaging, printing, semiconductor and factory automation. . See an example below: A package oem that is trying to make its machine output exceed 150 pieces per minute. The challenge is that the flexibility of the gearbox on a critical axis was introduced when they tried to increase production. Mechanical interference. By installing a modular direct drive rotary motor in this axial direction, the mechanical flexibility is eliminated, enabling the oem to increase the output of its machine to 180 pieces per minute. In addition to increasing production, the oem also realized the following benefits: zero maintenance workload, improved reliability and reduced auditory noise.
Another example of a modular direct drive application: an oem provides test/measurement equipment for tire and automotive industry services, the company found that using direct drive technology improves measurement quality and machine reliability by eliminating invalid travel And other external influences brought by the belt and pulley system. Their original design used a frameless direct drive motor, which brought many benefits compared to conventional solutions, but also had the disadvantage of being difficult to assemble and install – in fact, the combination and feedback of frameless motors The alignment of the device takes a full day. As a result, the company turned to modular direct drive technology and found that because of its simple installation, integration took only about 30 minutes, saving time and money. In addition, they are happy to see that the modular motor has a higher torque density than the frameless direct drive model.
Due to its unique design, modular ddr motors are more competitive in price than traditional servo motors with mechanical drives. Even if its initial cost is slightly higher, the operating cost of this new technology is much lower than that of the traditional system in terms of the total service life of five years.
