The specifications of each type of servo motor have parameters such as rated torque, maximum torque and motor inertia. There is a correlation between each parameter and load torque and load inertia. The output torque of the selected motor should meet the motion conditions of the load mechanism. Claim.
The weight of the mechanism will affect the selection of the motor, and the motion conditions will also change the choice of the motor. When the inertia is larger, the larger the acceleration and deceleration torque are required, and the shorter the acceleration and deceleration time, the larger the motor output torque is required. When selecting the servo motor specifications, follow the steps below.
(1) Defining the requirements of the motion conditions of the load mechanism, that is, the speed of movement, the weight of the mechanism, and the manner of movement of the mechanism.
(2) Calculate the load inertia of the mechanism by calculating the appropriate load inertia according to the operating conditions.
(3) Select the appropriate selected motor specifications based on load inertia and motor inertia.
(4) Calculate the acceleration torque and the deceleration torque in combination with the servo motor inertia and load inertia of the primary selection.
(5) Calculate the load torque according to the load weight, configuration, friction coefficient, and operating efficiency.
(6) The maximum output torque of the primary motor must be greater than the acceleration torque and load torque.
(7) Calculate the continuous instantaneous torque based on the load torque, the acceleration torque, the deceleration torque, and the holding torque.
(8) The rated torque of the primary servo motor should be greater than the continuous instantaneous torque.
