Position and speed of electric motors

Electric motors used in automation systems usually require some control. Note a robot that pulls a machined part from a CNC lathe and places it on the tray of a transport vehicle. Their movements would be: coming out of a known position, starting and accelerating; when approaching a favorable position of attack to the piece, to decelerate until stop; approach the part at low speed; stop and grab the piece; start back and accelerate; decelerate to a favorable position to release the part in the vehicle; release the part.

The electric motors find here vm3538 involved in this movement must have acceleration and deceleration and positioning. They are critical controls because if the robot approaches the part in a wrong trajectory, depending on the approaching speed, it may collide with some accessory or break the part. The same could happen at the time of releasing the piece. In other situations, these controls are decisive for the quality and reliability of the work produced by the machines. For milling a part in a CNC machine, we usually use three electric motors, one for horizontal movements, another for vertical movements and a third for deep movements.
