Key terms: Plug-and-play simplicity, built-in precision, and excellent for prototyping.

Speed Series: When Fast Matters (Ø6mm - Ø22mm)

Best for: High-speed applications and weight-sensitive designs

Our four ultra-compact Speed Series models span Ø6mm to Ø22mm, reaching up to 63,200 rpm. Perfect for dental handpiece motors, laboratory mixer drives, cooling fan applications, handheld power tools, and precision pump systems. These excel in blood analyzer centrifuges, tattoo machine actuators, and model aircraft propulsion.

Need speed? Speed Series coreless motors reach up to 63,200 rpm while maintaining smooth, quiet operation. They're the go-to choice for medical automation, laboratory equipment, and anywhere high-frequency operation is essential.

Popular picks:

• MC0623: Ultra-high speed for medical tools

• YY1331-JS: Balanced performance for general high-speed needs

• GL1025: Compact option for space-constrained applications

Key terms: Incredibly smooth operation, lightweight design, and exceptional speed capabilities.

Quick Selection by Application

Building Robots or Automation Systems?

Start with Planet Series. If you're designing collaborative robots, the flat profile works perfectly as a servo joint for collaborative robot arms. Need an alternative to Maxon BLDC motor? Our Planet Series offers comparable performance with better value and local support.

Pro tip: Pair with our recommended gear reducers for optimal performance. Ask about our precision planetary gear reducer for AGV applications.

Working on Medical or Precision Devices?

Atom Series is your friend. The integrated encoders eliminate external wiring complexity, and the BLDC motor for medical automation applications provides the smooth, quiet operation medical devices demand.

Need High-Speed Performance?

Speed Series delivers. Whether it's surgical tools, laboratory equipment, or any application requiring quiet BLDC motor for home automation, these coreless motors provide unmatched smoothness.

Common Questions Answered

"How do I reduce backlash in my robot joint?" 

Combine our Planet Series motors with precision reducers. We can recommend the perfect low backlash harmonic reducer for industrial robots to match your motor choice.

"Can you customize motors for our specific needs?" 

Absolutely. Cosmotr works closely with Costr to provide custom brushless DC motor manufacturer China solutions, regularly modifying motors for unique applications. Our engineering team collaborates with yours to optimize performance.
