But when the speed exceeds 150% of rated speed, servo motor gradually saturated, motor torque will decline rapidly, so the speed stage can not be used as servo motor speed period. Therefore: We recommend the selected maximum motor speed is 140% of rated speed Motor rated speed: V (rpm)=Vmax(rpm)/140% Note: To get better control effect, select the maximum motor speed is 130% of rated speed...
  • Page 79 After the servo motor selection is completed, you can ask motor suppliers for corresponding motor torque constant value Kt (Nm / A). Note: The torque constant value Kt (Nm / A) is related to the servo motor technology, materials and motor rated speed V (rpm).
