Compact High-Speed Screw Dispenser
This case shows a compact mechanical dispenser that uses a μDD motor. It keeps dispensing stable and repeatable while helping reduce the overall size of automation equipment.
Keeps dispensing accuracy and stability, while helping miniaturize automation equipment.
To solve the size constraint that many automated systems face, this mechanical dispenser integrates a latest μDD motor in a compact layout.
1) What is a screw dispenser
A screw dispenser (mechanical dispenser) delivers material with high repeatability. It is widely used in automation lines where stable dispensing matters for yield and rework control.
Ether Corporation Japan’s “AMD Series” supports precise material dispensing and efficient supply in semiconductor production and precision equipment assembly.
(2) uDD motor models used in AMD series (AMD3, AMD7, AMD8)
Wide fluid range
• Supports low to high viscosity materials with controlled dispensing
• Handles small-volume dispensing for materials such as anaerobic adhesives
• Built for continuous operation
Durability for long runs
• Stable dispensing performance during continuous operation, including high temperature and high viscosity conditions
Lower maintenance and operating cost
• Gearless structure reduces wear parts and maintenance work
• Uses durable zirconia ceramic screw for longer life
• Uses carbide or ceramic cylinder to reduce wear and keep operation stable

(3) μDD motor role
Dispensing quality depends on stable rotation and repeatable control. A compact direct drive motor helps keep the mechanism small while maintaining steady screw motion. A gearless drive also reduces parts that wear over time.
