Overview
The SteadyWin WK5515 is a high-torque three-phase BLDC robot motor designed for compact robotics applications. With a 24 V nominal voltage, precise torque constants, and a low-profile 60 x 19 mm form factor, it suits humanoid robots, robotic arms, exoskeletons, quadruped robots, and AGV platforms. Engineers comparing compact robot motor and Frameless Motor style solutions can use the following verified specifications for integration and selection.
Key Features
- Robot motor based on a three-phase BLDC architecture for smooth, controllable motion.
- Nominal torque of 0.65 N.m with stall torque up to 1.26 N.m for high-load joints.
- Operates at 24 V with a nominal current of 1.6 A and stall current of 3.2 A.
- Nominal speed of 264 rpm and maximum speed of 558 rpm for a wide operating range.
- Compact motor size of 60 x 19 mm and 196 g weight for space-constrained designs.
- 14 pole pairs and defined rotor inertia of 456 g cm^2 for accurate dynamic modeling.
- Working temperature range from -20 to 80 °C with max demagnetization temperature of 120 °C.
- Suitable for integration into robot joints, including projects that evaluate Frameless Motor configurations and other custom drives.
