Frameless Brushless DC Motors
Lightweight, frameless motors delivering low inertia, high efficiency and high torque density in compact sizes for applications in the fields of robotics, automation, medical, industrial, semiconductors and more.
Frameless brushless DC motors are unique and versatile in a wide range of applications. Frameless BLDC motors fit more easily into small compact machines that require precision and higher torque density. Additionally, they can replace heavier, less efficient hydraulic components by decreasing operating and maintenance costs. These motors are also more environmentally friendly than others.
- High torque to inertia ratio for quick response and precision control.
- High torque density in a compact package.
- Large rotor inner diameter for easy cable routing.
- Standard 200 mm lead lengths.
- Low cogging torque for a smooth operation.
- Machine wound reliability with bondable magnet wire for a compact and reliant coil.
- Constructed with corrosion-resistant materials.
- Tested for performance and reliability.
- Class F insulation
- UL agency recognition
- RoHS compliant
- Surgical Robots
- Collaborative Robots
