Performance advantages of the new modular (Catridge) direct drive rotary motor technology
Deutz-Fahr is a Europe brand who produces lots of tractors and other farm equipments, while KHD acquired the FAHR, a leading company in the market of agricultural equipments, in 1968. Then the Deutz-Fahr was found. The range of horsepower are from 50 hp to 300 hp. It almost meets all the power needs of agricultural operations. The parts we can supply are for the trators which installed with Deutz engine, like 900 series, 1000 series, and 2000 series, like overhauling parts, Electrical Parts, cooling system parts, fuel system parts.

A related challenge for most direct drive rotary (DDR) motors is that if a closed or frameless direct drive rotation (DDR) solution is used (as an alternative) in a conventional servo motor system, it may result in associated costs. increase. To solve this problem, a new type of direct drive selection technology has emerged. This new technology is called Cartridge Direct Drive Rotation or Cartridge DDR TM, which combines the performance of a frameless direct drive rotary (DDR) motor with the ease of installation of a full frame motor.
working principle
The Cartridge DDR TM motor integrates a rotor, stator and factory-aligned high-resolution feedback device into a bearingless housing, making Cartridge DDR TM motors suitable for embedded applications in most existing bearing systems.
In addition, Cartridge DDR TM technology eliminates the need for belts or gear reducers to achieve the required system torque, making it easy to install the motor. The Cartridge DDR TM motor utilizes a compression coupling to connect the rotor directly to the customer's machine shaft and has designed a transport chuck that provides “ready-to-use†ease of operation in less than 30 minutes.
Advantages of Cartridge DDR TM
In addition to the advantages of quick installation, the Cartridge DDR TM motor eliminates mechanical drive components (eg, belts and gearboxes), significantly improving uptime during maintenance-free operation, and reducing noise to a minimum of 20 decibels. Cartridge DDR TM motors feature an advanced electromagnetic design with torque densities of over 50%, while factory-aligned high-resolution feedback devices offer up to 50 times higher precision than traditional direct drive rotary (DDR) motors.
The performance advantages of Cartridge DDRTM motor technology stem from its ability to combine the operation of a frameless direct drive motor with the ease of installation of a full frame motor, so Cartridge DDRTM motor technology can significantly reduce installation compared to conventional direct drive technology. Cost and operating costs.
in conclusion
The Cartridge DDRTM system represents a new direction for direct drive rotary motors, concentrating all the advantages of closed motors in a unique, bearingless design that combines the benefits of modular technology with competitive prepaid price points. And a combination of significantly reducing life cycle costs. The new machine design combined with direct drive technology has great potential for growth in the steelmaking, packaging, printing, semiconductor and factory automation industries.
