We know that the speed and acceleration of linear motors are higher than traditional Motors, so how fast is it? What are the ways to increase the speed and acceleration of a linear motor? Let Tongmao Linear Motor introduce the linear motor speed problem for you below.
The effective feed speed achieved by the traditional "rotating motor + ball screw" transmission form is 30m/min, and the acceleration is only 3m/s2.
The linear motor drives the worktable at a speed of 30 times that of the traditional transmission mode, and the acceleration is 10 times that of the traditional transmission mode, which can be as large as 10g.
The workbench driven directly by linear motor has no reverse working dead zone; Due to the small inertia of the motor, the linear servo system can achieve higher frequency response.
The greater acceleration that can be achieved by the linear motor bench is ax = Fmax-FRm.
M is the total mass of the feed moving parts. It includes three parts: the workbench quality, the primary quality of the motor, and the quality of the workpiece.
It can be seen that to increase the speed of addition(subtraction) of the feed unit, it is necessary to reduce the quality of the moving parts and increase the thrust of the system. The thrust of the system is related to friction, the type of linear motor, and the friction coefficient of the guide rail, and the quality of the moving parts can be reduced by optimizing the design of the worktable structure. According to the different installation methods of linear motor, the structure of feed unit can be divided into two basic ways: horizontal layout and vertical layout.
