In high-speed semiconductor sorting and packaging equipment, turret indexing must achieve two goals at the same time: short cycle time and repeatable positioning accuracy. Many engineers initially assume that the key to faster turret indexing is simply using a higher-power motor. In practice, however, the performance of the complete transmission system is often more important than motor power alone. A conventional turret drive may use a servo motor combined with a gearbox, coupling, belt or other mechanical transmission components. These components can introduce backlash, elastic deformation, friction, transmission error and additional inertia. A Direct Drive Motor takes a different approach. By directly connecting the motor to the turret, the system can eliminate the need for a conventional reduction gearbox and reduce the number of mechanical transmission components between the motor and the rotating load.

The TDB-080-050-NH-RD-T DD motor features a compact direct-drive structure with an outer diameter of 80 mm and a height of 50 mm, making it suitable for applications requiring high-precision rotary positioning and stable torque output. This model provides a continuous torque of 0.6 N·m, a peak torque of 2 N·m, and a maximum speed of 450 rpm. Equipped with an RD encoder and a sensorless design without Hall sensors, it offers fast response, minimal backlash, smooth operation, and high positioning accuracy. It is well suited for applications such as automated rotary tables, precision inspection systems, semiconductor equipment, and high-end medical devices.
