Each type of servo motor has parameters such as rated torque, maximum torque and motor inertia in the specifications. There must be a correlation between each parameter and load torque and load inertia. The output torque of the selected motor should meet the load mechanism. The requirements of the movement conditions,Servo Motor such as the speed of acceleration, the weight of the mechanism, the movement mode of the mechanism (horizontal, vertical, rotation), etc .;Servo Motor the movement conditions are not directly related to the motor output power, but generally the higher the motor output power, the relative output torque Will be higher.
Therefore, not only the weight of the mechanism will affect the selection of the motor, but the movement conditions will also change the selection of the motor. The greater the inertia, the greater the acceleration and deceleration torque, and the shorter the acceleration and deceleration time, the greater the motor output torque. When selecting the servo motor specification, follow the steps below.
Clarify the movement conditions of the load mechanism, that is, the speed of acceleration / deceleration, the speed of movement, the weight of the mechanism, the movement mode of the mechanism, etc. According to the requirements of operating conditions, a suitable load inertia calculation formula is selected to calculate the load inertia of the mechanism. According to the load inertia and motor inertia, Servo Motor select the appropriate falsely selected motor specifications. Combined with the servo motor inertia and load inertia of the initial selection, the acceleration torque and deceleration torque are calculated. The load torque is calculated according to the load weight, configuration method, friction coefficient, and operating efficiency.
The maximum output torque of the primary motor must be greater than the acceleration torque + load torque; if the conditions are not met, other models must be selected for calculation and verification until they meet the requirements. Based on load torque, acceleration torque, deceleration torque and holding torque, Servo Motor continuous instantaneous torque is calculated. The rated torque of the primary servo motor must be greater than the continuous instantaneous torque. If the conditions are not met, other models must be selected for calculation and verification until they meet the requirements. Complete the selection.
