There are a great variety of robot products on the market currently. Many merchants use robots to perform various shows, such as dancing and wrestling, to attract customers. However, currently, robots can only perform some simple actions. Don't underestimate these actions, as they cause significant wear and tear on the servo motors inside the robots, especially in humanoid robots, resulting in a very high repair rate in the robot industry.

Servo motors are very important components in robot products. They are composed of mini - micro servo motors, gear sets, sensors, and other components. In robot applications, mini - micro servo motors act as connectors that link various mechanisms, just like the joints in our human body. Through the drive of mini - micro servo motors, various actions can be achieved. Servo motors determine the smoothness and accuracy of the actions of robot products. Therefore, in terms of both the structure of servo motors and the performance of micro - motors, enterprises are trying various ways to improve.

Take the force of mini - micro servo motors as an example. The force of mini - micro servo motors on the market is already designed during the R & D phase. If you want to increase the force of mini - micro servo motors, it can only be achieved by increasing the voltage and current. However, this will cause certain damage to the motors of mini - micro servo motors. So, the requirements for mini - micro servo motors are relatively high. Tianfu N20 motors are widely used in servo motors, and the force is increased through the gear sets inside the mini - micro servo motors.

Operation Methods of Robot Servo Motors

Although there are many types of servo motors available for robot enterprises to choose from in the market, the operation methods of different servo motors vary. The differences mainly lie in the structure and PID operation. Different types of servo motors are applied in different places (for example, 9g servo motors are often used at the joints of robots), which will lead to differences in PID operation, output torque, etc. Simply put, different PID operations of servo motors will directly affect the torque required for the servo motor to reach the target angle in a certain time. Even servo motors with the same appearance will produce completely different effects at the same position if there are differences in PID operations.

Therefore, when choosing a servo motor, it is necessary to select and match it according to a specific part. The hand joints of robots require precise control, so the stability and accuracy of the servo motor need to be considered. For the legs of robots, which need to support the balance of the robot's body, the torque of the servo motor needs to be considered.

For servo - motor motors, brushless motors are undoubtedly a better choice, but the cost is too high. In addition, as robot products perform various actions for a long time, an increase in the repair rate will undoubtedly increase the cost. Therefore, most enterprises still choose brushed DC motors, or use brushless motors for the servo motors in some parts.

If you want to ensure the stability and service life of servo motors, you can only minimize the running time of servo motors and reduce the wear and tear of micro - motors and gears to effectively increase the lifespan and stability of servo motors. However, this seems not to be in line with the current usage characteristics of robot products. Therefore, reducing the repair rate of servo motors is currently a major challenge.

Tianfu Motor mainly focuses on the R & D and production of micro - motors and has always been well - received by users in robot servo motors. As the requirements of robots for servo motors are getting higher and higher, our company has never stopped the R & D of servo - motor motors, aiming to produce micro - motors suitable for various servo motors.
