Overview
The SteadyWin WK10025 is a frameless outrunner Robot Motor designed as a high-torque Frameless Motor solution for compact robotic joints and direct-drive actuators. With a nominal torque of 4 N m at 36 V and high power density, it supports precise, zero backlash motion control in advanced humanoid, mobile and industrial robotic systems.
Key Features
- Frameless outrunner Robot Motor for direct integration into robotic joints and mechanisms
- 36 V nominal voltage with 3.8 A nominal current for efficient operation
- High torque capability: 4 N m nominal torque and 8.5 N m stall torque
- Nominal speed of 168 rpm with up to 330 rpm maximum speed
- High pole count (21 pole pairs) for smooth low-speed control
- Stator inner diameter of 78 mm and outer diameter of 109 mm for compact, high power density designs
- Wide working temperature range from -20 to 80 °C with 120 °C maximum demagnetization temperature
- Lightweight 576 g construction for weight-sensitive robotic applications
- Available 2D installation drawings and 3D STEP models to simplify mechanical and system integration
