Product Overview
The JY-IHM140-085-48-C is a 5.5-inch integrated servo hub motor that combines the servo drive and hub motor in one compact unit. It is easy to install and reduces both internal vehicle-space requirements and external wiring.
The product uses a Ø140 mm polyurethane wheel and provides 8.5 N·m rated torque, 25.5 N·m maximum torque and 1.54 m/s rated linear speed. It features high torque, strong overload capacity and smooth low-speed operation.
With an IP65 protection rating, RS485 commissioning and CANopen communication, the product is suitable for cleaning, disinfection, inspection, delivery and guidance robots, as well as AGV material-handling equipment and compact medical-device systems.
Key Features
Integrated Drive and Hub Motor
The servo drive and hub motor are integrated into a compact unit, reducing external wiring and simplifying installation.
High Protection Rating
The complete unit is rated IP65 for use in cleaning, inspection, logistics and other mobile-equipment applications.
High Torque and Strong Overload Capacity
Rated torque is 8.5 N·m and maximum torque is 25.5 N·m, meeting the starting, acceleration and variable-load requirements of mobile equipment.
Smooth Low-Speed Operation
A single-turn communication magnetic encoder and servo control support smooth low-speed operation and precise speed control.
Standard Industrial Communication
RS485 commissioning and standard CANopen communication simplify connection to robot controllers and higher-level control systems.
