Bextreme Shell Smart Servo Motor Resistance System

1: This intelligent resistance system adopts high-precision, high-speed FOC servo control mode to provide accurate, stable and smooth resistance output, the maximum resistance output is 110kg , can be steplessly adjusted, the system structure is compact, the motor weight is only 4.8kg, can be easily and quickly applied to aerobic models and anaerobic power equipment.

2: Different from the traditional mechanical iron sheet load, this system can give rich system data, such as pull-out distance, pull-out strength, pull-out speed, retraction strength, training time, etc., relying on accurate and rich data output, it is easy to realize data acquisition and analysis, achieve accurate analysis of exercise effects, facilitate background user data management, and make more scientific training plans and courses for users.

3: Rich training modes, this system has concentric mode (pull-out force is greater than retraction force), eccentric mode (pull-out force is less than retraction force), elastic mode (the farther the pull-out distance, the greater the force), vibration mode (motor high-frequency vibration, can relax the muscles after training), professional mode (can be adjusted arbitrarily according to user habits)

4: The system has a unique patented motion protection mode--- safety centrifugal rope return mode (SSR), this technology can be turned on and off according to user habits, this safety technology can limit the speed of the rope return in large resistance (more than 20kg) mode to achieve the purpose of safety protection beginners.

5: Rich communication interface, UART, USB, CAN ports to adapt to the development needs of different customers, the system's communication protocol compatibility is high, compatible with different national protocol formats (HEX, ASCII, etc.).

6: Rich team industry experience, not only provide technical support for resistance system, but also provide professional machine development assistance, help customers avoid detours, quickly complete the process of complete products.
