T/CAEE 046-2026 Axial Flux Motor for Humanoid Robot Joints

Scope

This document specifies the terms and definitions, product classification and naming, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage, as well as quality commitments for axial flux motors used in humanoid robot joints (hereinafter referred to as "joint motors"). This document applies to permanent magnet synchronous axial flux motors used in the rotating joints of various humanoid robots, including core joints responsible for torso and limb movement, as well as micro-joints of dexterous hands. 4. Product Classification and Naming Product Classification This document classifies axial flux motors used in humanoid robot joints according to cooling methods, integrated functions, performance parameters, installation methods, and types of supporting components, with the specific classification rules as follows. 4.1.1 Classification by Cooling Method a) Natural Cooling Type: Relying on the natural heat dissipation of the motor housing without additional cooling devices; b) Forced Air Cooling Type: Equipped with active cooling devices such as fans or blowers; c) Liquid Cooling Type: Realizing heat dissipation through cooling fluid circulation, including water cooling and oil cooling. 4.1.2 Classification by Whether a Brake Is Integrated a) Basic Type (without brake): Only including the core components of the motor body, without a power-off brake function; b) Brake Type (integrated with a power-off brake): Integrating a power-off brake device, which automatically locks the rotor when power is cut off. 4.1.3 Classification by Whether a Driver Is Integrated a) Motor Body: Only including the core components such as the stator, rotor, bearings, and housing, requiring an external driver; b) Mechatronic Module (integrated with a driver): Integrating a driver, controller, and related interfaces, which can be directly connected to the control system. 4.1.4 Classification by Output Torque Grade a
