The linear motor is simpler than other motor structures, but the simplicity of the linear motor does not represent its weakness. The following is a brief introduction to the advantages of the simple structure of the linear motor.
The linear motor can move without mechanical contact, so that the transmission parts do not wear, thus greatly reducing the mechanical loss. The full closed-loop control adopted by the linear motor refers to the fact that the motor body is equipped with a grid ruler and the position of the mover is feedback at all times. Because the position accuracy of the grid ruler is very high, the load driven by the linear motor can improve the control accuracy. The linear motion of the general rotary motor, its mechanical structure in operation, noise is inevitable; The linear motor is operated by an electromagnetic thrust drive device, so the noise of the entire device is small or no noise, and the operating environment is good.
The linear motor is exposed to the air due to the primary iron core and winding ends. The secondary is very long, has a large heat dissipation surface, and the heat is easily emitted. Therefore, the thermal load of the linear motor can be achieved at a high level and does not require additional cooling. Device.
The primary iron center of a linear motor can be sealed as a whole with epoxy resin after being inlaid, so it can be used in some special occasions. For example, it can be used in wet or even water and can be used in corrosive gases or toxic and harmful gases, even at high or low temperatures.
The dynamic response speed of linear motor is not comparable to that of normal servo drive mode. Drive by linear motor can greatly improve the machining efficiency of equipment.
