Direct drive motor

DDL Direct Drive Linear Motor

1. Simple structure

The additional device for converting rotary motion into linear motion is eliminated, and the weight and volume are greatly reduced.

2. High positioning accuracy

Linear motors can achieve direct transmission, eliminating various positioning errors caused by intermediate links, so the positioning accuracy is high.

3. Safe, reliable and long life

Linear motors can achieve contactless transmission of force, and the mechanical friction loss is almost zero, so there are fewer failures and maintenance-free, so the work is safe, reliable and long life.

4. No wear or maintenance-free

Linear motors have fewer parts, and do not require nuts, bearing seats, couplings, motor bases and other ball screw parts, nor do they need to maintain such parts. Therefore, the service life is extremely long, the operation is clean, and there is no need to lubricate or maintain such parts.

5. Unlimited stroke

The stroke of the linear motor can be unlimited by splicing the stator, and multiple independent motion controls in the same axis can also be achieved by configuring multiple movers on the same stator.

DDR Direct Drive Rotary MotorsNo wear or maintenance-free

DDR motor is a torque motor that directly drives the load without any transmission components. DDR motors are compact and rigid. They generate high torque by using high-energy permanent magnets. At the same time, the built-in optical encoder gives the system better positioning accuracy and higher dynamic response. The use of high-rigidity cross roller bearings improves the mechanical characteristics of the system.
