Customization and Sourcing Notes
OEM/ODM customization is available for voltage, speed, torque, shaft design (dual shafts, knurled shaft), cable or connector options, gearbox integration, control options, wiring (pre-soldered leads or terminal connectors) and EMC/EMI suppression (varistors, capacitors). Shaft diameter and motor length can be adapted; example shaft diameter: 2.3 mm, example motor length: 32.6 mm.

Target Applications & Solutions
Designed for high-speed and sustained operation, the ST series features an optimized magnetic circuit and winding design with ventilated cooling suitable for continuous duty. Typical use cases:

• Automotive washer pumps & outdoor equipment: Suitable for washer pumps, inflators and electric mobility products. Stable operation at 36V–48V with starting torque up to 500 g·cm for pump and drive mechanisms.
• High-speed hair dryers & vacuum cleaners: Used in household hair dryers, handheld vacuum cleaners and robotic vacuum cleaners. Speeds up to 25,000 rpm deliver high airflow while vented housings reduce heat buildup during high-speed operation.
