DC wheel motor PX series

48 Vretrofittingfor humanoid robot

Introduction
This product is an advanced omnidirectional steering wheel motor designed for intelligent mobile robots. It overcomes the steering-angle limits of conventional steer wheels, enabling continuous 360° rotation and true multi-directional movement. With a fixed wiring harness design, it eliminates cable wear and entanglement risks, extending the service life of critical electrical components by more than 10×. Suited for AGVs, AMRs, humanoid robot chassis and other mobile robotic platforms, it is proven reliable in demanding environments such as cold-chain logistics, factories and warehouses.

Features
Omnidirectional mobility without steering limitations

• Supports unlimited 360° continuous rotation, removing the traditional ±135° steering constraint.
• Enables lateral translation, zero‑radius turns and smooth navigation through narrow aisles and complex paths.
• Significantly improves maneuverability in dense, confined and dynamic operating environments.

Optimized wiring harness design for superior durability

• Fixed wiring harness architecture prevents repetitive bending, twisting and friction during steering motions.
• Eliminates cable wear and breakage risks at the root.
• Extends the service life of critical electrical connection components by more than 10×, reducing maintenance and operating costs.

High installation flexibility and simplified vehicle integration

• Compatible with a wide range of vehicle platforms and chassis configurations.
• Simplifies installation and integration, lowering engineering complexity.
• Helps shorten AGV development and retrofit cycles to improve deployment efficiency.

Excellent adaptability to diverse operating conditions

• Deployed successfully on humanoid robot chassis, e‑commerce sorting centers, 3C electronics manufacturing, pharmaceutical warehousing and similar applications.
• Capable of carrying loads above 300 kg while maintaining smooth, precise motion in fresh‑food cold‑chain environments down to −18°C.

Redefining mobile platform performance

• Provides system‑level optimization in motion freedom, electrical reliability and overall vehicle maneuverability.
• Designed for intelligent factories, automated warehouses and next‑generation robotic platforms requiring maximum mobility and flexibility.
• Enables AGVs and mobile robots to achieve greater versatility, efficiency and operational performance.
