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.
Relying on years of experience in the research and development of
brushless DC motor products, after 4 generations of motor design
improvement and update, the final manufacture of a large torque
servo motor suitable for use in the fitness industry.
1.Input voltage: 36-48VDC
2.Max torque:45N.M
3.Rotate speed: 450rpm
4.Diameter of the capstan:80-85mm
5.Max resistance output: 115kg(250Lbs)
6.Diameter of the motor:170mm
7.Width of the motor(include shaft): 155mm
8.Weight: 4.7kg
In order to pursue the ultimate experience in the fitness process
of the end user, the servo controller has undergone 14 software and
hardware debugging upgrades, striving to match the servo motor with
the best degree and achieve the maximum silky smoothness.
High performance servo controller Beedrive V2.4

Recommended motor installation
One fan dissipates heat from both the motor and the controller
The smart Servo motor resistancce system fits well with most
fitness equipment.
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.
