Bextreme Shell Servo Motor And Controller For Fitness Equipment ,Torque 45NM

Smart Servo Motor Resistance System Presentation

 

• The benefits of the Technolog

1: This intelligent resistance system adopts high-precision, high-speed FOC servo control mode to provide accurate, stable and smooth resistance output, the maximum can reach 115kg output, can be steplessly adjusted, the system structure is compact, the motor weight is only 4.7kg, 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.

Our finished product

 

• Interaction and control

1.We have developed our own knob screen to set the system resistance strength on the knob screen

 

2.No need for cumbersome operation, can quickly set parameters for exercise, can also built-in Bluetooth module, easy to connect with APP.

 

3.In the future, we will develop more screen sizes to meet the needs of different models

 

4.The development of serial port screen is relatively easy, and the hardware cost is low, which is more suitable for the transformation and upgrading of large-scale equipment

 

 

 

 

 

• App development planning

1.At present, we have an APP on the Window side, which currently implements function settings and some data display.

 

2. In addition, we have cooperated with some well-known apps, such as Fitshow and Jianyan Sports, and our communication protocol has been opened with them.

 

3.In the future, we plan to build a fitness equipment development platform APP with our resistance system as the underlying actuator, so that customers can get their own brand APP at a small cost.
