Description

Technical field

The present disclosure belongs to the technical field of motor manufacturing, and particularly relates to a mover assembly and a linear motor.

Background technique

Linear motors have the characteristics of high accuracy, high acceleration, high responsiveness, and high thrust. They are widely used in industrial fields, especially high precision machining. When the linear motor is working, the winding generates a lot of heat in a short time, and at the same time, the core and iron consumption will also generate a certain amount of heat, which will cause the temperature of the entire motor to be too high. On the one hand, excessive temperature rise may cause the wire such as the coil to exceed its temperature resistance limit. As a result, its insulation layer is damaged; on the other hand, heat will be transmitted to the work platform along with the installation plane, which will cause thermal stress and reduce the repeated positioning accuracy of the motor. At the same time, linear motor applications generally have high requirements on the external temperature of the motor. Excessive temperature may even affect the performance of adjacent mechanisms; in addition, excessive temperature rise of the iron core teeth of the motor will also radiate to the motor mover, and the temperature of the magnetic steel will increase, which will cause the performance of the magnetic steel to decrease, which will affect the working efficiency of the motor. Therefore, it is necessary to perform necessary cooling on the linear motor rotor core.

There are two main types of linear motor cooling. One is to cool the contact part of the linear motor and the working platform.

The independent first cooling pipe 2 has high assembly flexibility Of course, the first cooling pipe 2 is preferably an integrated molding structure, which can effectively prevent the hidden danger of leakage of cooling water that may be caused by the use of the assembled structure.

Further, the mover core 1 further includes a yoke portion 13, and the first cooling pipe 2 further includes a first yoke portion tube section 22, and the first yoke portion tube section 22 can cool the yoke portion 13. Thereby, the first cooling duct 2 can simultaneously cool the tooth portion and the yoke portion of the mover core 1, and the temperature rise control effect is better. Of course, the first yoke section 22 can be embedded in the groove of the yoke section 13 of the mover core 1, but this method will undoubtedly increase the difficulty of processing and manufacturing the mover core 1. Therefore, optionally, the first A yoke section 22 is in contact with the yoke section 13 away from the first tooth section 11. The contact here specifically means that the outer peripheral wall of the first yoke section 22 is at least partially placed on the outer surface of the yoke section 13. It can be understood that It is because the yoke section 13 is close to the load mounting platform when the linear motor is assembled and applied, so the yoke section 22 can also maximize the timely cooling of the load mounting platform.

Optionally, the number of the first toothed pipe section 21 is multiple, and the specific number may be matched with the number of the first toothed pipe 11, and may include A toothed pipe section 211, B toothed pipe section 212, and A toothed pipe section 211.

The specific position arrangement between the second cooling pipe 5 and the first cooling pipe 2 may be various. Optionally, the pipe direction of the second toothed pipe section 51 is parallel to the pipe direction of the first toothed pipe section 21, The first toothed pipe section 21 and the second toothed pipe section 51 are arranged in order along the depth extension direction of the receiving groove 12, that is, a double toothed pipe section 21 and a second toothed pipe section 51 are formed in the depth direction of the receiving groove 12. The layers are arranged in layers to make the area where the first toothed pipe section 21 and the second toothed pipe section 51 contact the groove wall of the receiving groove 12 larger, which is beneficial to further improving the heat exchange and cooling effect.
