First of all, choose which power control speed control, torque control or position control according to your actual situation; The speed and torque of the actual working condition should be less than or equal to the rated parameters of the selected servo motor, due to the consideration of cost as close as possible and the brand with high cost performance.
In general, the selection of servo motor must meet the following conditions:
● Maximum motor speed> maximum moving speed required by the system;
● The rotor inertia of the motor matches the load inertia;
● Continuous load working torque ≦ the rated torque of the motor;
● Maximum output torque of the motor> the maximum torque required by the system (torque during acceleration).
Servo Motor Selection Calculation:
● The correct formula T = 9550P/ n can only be calculated by this formula under rated conditions;
● Inertia Matching Calculation (JL/JM);
● Rotation speed calculation (load end speed, motor end speed);
● Load torque calculation (continuous load working torque, torque during acceleration).
Servo motor is expensive, especially Japanese servo. It pays attention to cost budget. It is best to match the machine just right. If the torque is too large or too small, it will vibrate.
