Product Description
The axial magnetic field motor of the legged robot joint is designed for flexible movement. The flat disc structure is compact in axial direction, the volume is halved, and the lightweight adapts to small spaces. The magnetic circuit is optimized, the power density and torque are high, and the stable driving walking, climbing and other actions are achieved. The power transmission is reliable in complex terrain. The low inertia rotor is sensitive to response and the gait switching is smooth. The fully enclosed protection is wear-resistant, durable and maintenance-free. It is widely used in four-legged inspection robots, bipedal bionic robots, etc., providing efficient and stable power for scientific research, logistics, rescue, etc., helping robots achieve agile and dynamic breakthroughs.
Functional Features
High power density: Compact and flat structure, powerful torque output in a limited space, higher power density than traditional motors, easily cope with high load requirements of complex movements of legged robots, and ensure strong and stable power.
High efficiency and energy saving: Axial flux path design shortens magnetic circuit length, reduces energy transmission loss, and with good heat dissipation performance, it can maintain high efficiency and stability for long-term operation and reduce energy consumption.
Quick response: The rotor has light weight and low moment of inertia, can quickly respond to control instructions, and achieve millisecond-level action switching, making the legged robot agile and precise, and easily adapt to changing environments.
Lightweight design: Optimize structure, reduce material use, significantly reduce its own weight, effectively reduce the overall load of the legged robot, and improve flexibility and endurance.
Flexible customization: The size and shape can be flexibly adjusted according to the special needs of different legged robot joints, which is convenient for integration with reducers, sensors and other components, and simplifies the system architecture.
