Manhart How to determine the rated power of the motor for a servo bending machine?

When determining the rated power of the servo bending machine motor, multiple factors need to be comprehensively considered to ensure that the motor can meet the working requirements of the equipment and operate stably. The following are the steps and key points on how to determine the rated power of the servo bending machine motor:
1、 Consider the power and working mode of mechanical loads
1. * * Load type and working mode * *: Different types and working modes of loads have a significant impact on the rated power of servo motors. Generally speaking, the greater the inertia of the load, the greater the rated power.
2. * * Calculate required power * *: According to the power and working mode of the mechanical load, use the formula (such as P=F * V/1000, where P is the calculated power KW, F is the required pulling force N, V is the working machine linear speed M/S) or analogy method to calculate the required rated power.
2、 Considering the actual working time ratio and environmental factors
1. * * Adjust required power * *: Adjust the calculated rated power based on the actual working time ratio.
2. * * Consider environmental factors * *, such as ambient temperature and altitude, which may affect the rated power of the motor, and therefore require appropriate correction.
3、 Choose the appropriate motor rated power
1. * * Reserve margin * *: To ensure stable operation of the motor under various working conditions, a servo motor with a rated power slightly higher than the calculated rated power should be selected, and a certain margin should be left.
2. * * Reference Motor Data Manual * *: Obtain key parameters such as rated current, rated speed, and rated torque of the motor from the servo motor data manual or model parameters.
4、 Using specific formulas for calculation
1. * * Formula based on motor parameters: Rated power=rated current x rated torque x 2 π x rated speed/60. Through this formula, the rated power of the motor can be calculated based on its specific parameters.
For example, assuming a servo motor has a rated current of 10A, a rated speed of 4000rpm, and a rated torque of 40%, the formula can be used to calculate the rated power of the servo motor to be approximately 83.8W.
5、 Comprehensive verification and debugging
1. * * Verify calculation results * *: After preliminarily determining the rated power of the motor, actual testing or analogy should be used to verify whether the selected motor’s power is appropriate.
2. * * Debugging and Optimization * *: Fine tune the parameters of the motor based on the test results to achieve the best operating effect.
In summary, determining the rated power of the servo bending machine motor is a process that comprehensively considers multiple factors. By carefully calculating and selecting appropriate motor parameters, it can be ensured that the motor can meet the working requirements of the equipment and operate stably.
