SteadyWin WK8115 Frameless Robot Motor 24V/36V, High-Torque 90x19 mm Hollow Core Frameless Motor for Robotics

Overview

The SteadyWin WK8115 is a compact frameless robot motor designed for high-performance robotic joints and automation systems. As a frameless motor with a 90 mm outer diameter and 58.5 mm stator inner diameter, it offers high power density and precise control for humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, ARU robots, and advanced consumer devices.

Key Features

• High power density – Delivers substantial output in a slim 90 x 19 mm package, ideal where installation space is limited.
• Ultra-low rotational inertia – Supports very fast acceleration and deceleration for responsive motion in pick-and-place and interactive systems.
• Enhanced thermal behavior – Construction supports effective heat dissipation, helping maintain stable performance under extended operation.
• Precision control – Motor constants and low cogging enable accurate, smooth movement for high-precision robotics and automation.
• Versatile integration – Frameless design with a 58.5 mm inner stator diameter simplifies integration into custom joint modules and compact electromechanical assemblies.
• Dual variants – Available as WK8115_1 (24 V) and WK8115_4 (36 V) to match different drive and system voltage requirements.
