UNITED MOTION INC. is highlighting an integrated hub motor solution designed to support the mobility and drive requirements of robotic lawn mowers. Combining a compact hub structure with an integrated reduction mechanism, the motor is designed to simplify drive system integration while addressing the challenges of outdoor operation, limited installation space, and variable working loads.
Compact Design for Simplified Drive Integration
The Greensky 80 Series hub motor integrates the reduction mechanism into the wheel-end drive unit, helping OEM manufacturers optimize chassis layouts and reduce the need for additional transmission components.
With an approximate outer diameter of 85 mm and a main body axial dimension of 66.1 mm, the motor offers a compact configuration for robotic lawn mower platforms where installation space is limited. Its integrated design can help manufacturers streamline mechanical integration and reserve more space for other essential components.
Low-Speed Torque for Robotic Mobility
Designed for robotic lawn mower traction applications, the motor features a rated voltage of 18 V DC, a rated output torque of 2.8 N·m, and a rated speed of 100 rpm.
These specifications provide a basis for matching the motor to wheel-end drive requirements, including low-speed movement and changing ground resistance. Actual climbing capability and traction performance depend on the complete machine design, including vehicle weight, wheel diameter, tire grip, chassis configuration, and motor control strategy.
Feedback and Protection for Outdoor Applications
Outdoor robotic equipment requires careful consideration of moisture, dust, and changing operating loads. The motor drawing specifies an IP67 protection rating and incorporates Hall A/B/C position feedback and a B3950 10K NTC temperature sensor.
Hall feedback provides rotor position information to support motor commutation, starting, speed regulation, and reversing when properly matched with the controller. Temperature feedback can also support protective strategies such as current limiting, power derating, or shutdown when operating temperatures rise.
These features provide a foundation for developing reliable drive systems for outdoor robotic equipment. Final protection performance and thermal management should be confirmed through appropriate testing under the intended operating conditions.
Supporting OEM Customization and System Integration
For robotic lawn mower manufacturers, motor selection involves more than rated torque and speed. Mechanical installation, controller compatibility, thermal behavior, wheel traction, and environmental protection all influence overall system performance.
UNITED MOTION INC. supports OEM customers in evaluating motor solutions against their specific application requirements. By considering the motor, controller, wheel, and chassis as an integrated system, manufacturers can make more informed decisions during product development and drive system selection.
The Greensky 80 Series hub motor provides a compact drive option for robotic lawn mower applications, with integrated reduction, Hall feedback, and temperature sensing to support system integration and control design.
