Product Description
This motor offers excellent performance, high speed operation and high torque output to meet the demands of a wide range of harsh operating conditions. It has integrated Hall commutation (optional) and integrated temperature switch (optional) design, which can flexibly adapt to different use scenarios to achieve accurate regulation and safety protection. It is especially suitable for multi-station precision indexing plate control applications to ensure efficient, stable and accurate operation of equipment.


Functional Features
1. Can withstand high load
High rigidity cross roller bearing with high load capacity. In operation, it can withstand load fluctuations (no need for support structure design).
2. Absolute coder type
The built-in absolute encoder provides absolute positioning.
3. Flexible design can be done mechanically
Mechanically speaking, because the DDR has no gear structure, the station of motion can be easily changed through the program. The change of the station of the normal gear structure requires changing the gear ratio.
4. High-performance drives
The drive improves motor control and maneuverability. It has a self-tuning function and can automatically match the moment of inertia and parameters. It can be used to realize the compatibility of field network.

Application
Frameless torque motor as an advanced special motor, the structure only retains the stator and rotor, abandoning the traditional shaft, bearing, housing and other components, with compact, flexible characteristics, become the ideal power source for many industrial equipment machinery. In the semiconductor process, from the photolithography and etching of chip manufacturing to wafer detection, frameless torque motors accurately control equipment movement by relying on the advantages of high torque density, low speed and large torque output to ensure high precision and high yield of chip processing. In the field of liquid crystal manufacturing, whether it is the handling of the glass substrate, the liquid crystal drip, or the module assembly, the frameless torque motor has the characteristics of fast response speed and high positioning accuracy, helping the equipment to achieve high-speed and stable operation and ensuring the high-quality production of the liquid crystal panel.
