1. First define the user parameters: such as the maximum torque, the maximum speed, the moment of inertia of the swing part.

2. According to this, determine the model of the servo motor (three principles: inertia matching, torque matching, speed matching), and then verify whether the maximum torque exceeds the maximum torque of the selected motor. (About whether the servo motor needs to be accelerated or not, if the load you want to bring is less than the rated torque of the motor, you can not add the reducer, but if the load of your motor is greater than the rated torque of the motor, you must increase the reducer. But the servo motor In low-speed mode for a long time, it is a waste of motor power. Generally, acceleration and deceleration are used to decelerate!)

3. At the same time, the design of the rotating shaft is optimized while ensuring the bending strength and torsional strength. After determining the shaft diameter, select the bearing size and fit system. Finally completed the structural design of the shaft.

4. Determine the installation method of the servo motor and reducer,

5. Servo motor control can be controlled by using PC usb to 232 serial port, or using can bus. The host computer can be programmed by platform software such as VB or labview. It is recommended to use a hollow cup motor for the servo motor, which has fast response, high energy utilization rate and stable torque.

Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect speed change device.

The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage, which can convert the received electrical signal. Converted to angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.
