¡¡¡¡Linear motor selection, we have to know the linear motor acceleration, can calculate the thrust of the linear motor size, then the linear motor acceleration how to calculate it, the following with Mao straight line motor to teach you to calculate the linear motor acceleration.
¡¡¡¡Usually we do not know the actual acceleration requirements, but we have the actual requirements of the motor running. Given the travel distance and the required travel time, it is possible to calculate the required acceleration. In general, for short strokes, it is recommended to use the triangular speed mode, that is, no uniform motion, long stroke, the trapezoidal speed mode is more efficient. In the triangular velocity mode, the motor movement is not evenly segmented.
¡¡¡¡Triangle mode acceleration is£ºAcceleration = 4 x Distance / Travel_Time2
¡¡¡¡The trapezoidal mode requires a constant speed value set in advance, whereby the acceleration can be calculated.
¡¡¡¡Acceleration = constant speed / (movement time - displacement / uniform speed)
¡¡¡¡Similarly, the calculation of the deceleration is similar to the calculation of the acceleration, and in special cases there is an unbalanced force (eg gravity) acting on the motor. In general, in order to maintain the uniform process and stagnation stage, friction and external stress should also be taken into account, in order to maintain uniform speed, the motor will be against friction and external stress, the motor will stop when against external stress.
¡¡¡¡Since we know how the acceleration of the linear motor is calculated, what factors can affect the acceleration of the linear motor when we use the linear motor workbench?
¡¡¡¡To increase the feed rate of the feed unit, it is necessary to reduce the mass of the moving part and increase the thrust of the system. The thrust of the system is related to the friction force, the type of linear motor, and the coefficient of friction of the guide rail, and the quality of the moving parts can be reduced by optimizing the design of the table structure.
