Description

  The present invention relates to a permanent magnet DC motor, and more particularly to an automatic production line for a motor for preventing corrosion and a motor for preventing corrosion.

  Plastic packing permanent magnet brushless DC motors are widely used and widely used in the field of home electric appliances, and the motor is one of the very important components in the entire apparatus.

  At present, the plastic packing brushless DC motor controls the rotation speed and torque of the motor rotation by a PWM pulse width modulation method with a frequency of 8 to 22 KHz. When the rotation of the motor is controlled by PWM pulse width modulation of 8-22 KHz, which is a high frequency, an induced current is generated between the end cover of the motor, the stator core, the bearing outer ring, the bearing ball, the bearing inner ring, and the rotating shaft, The induced current causes grease in the bearing to be discharged, so that ball races and ball erosion occur in the inner and outer races of the bearing, causing bearing noise due to the bearing and affecting the service life of the motor.

  At present, the following two methods are mainly employed in the structure for preventing corrosion of a DC motor according to the prior art.

  As one method, the objective is to reduce the equivalent capacitance of the motor and reduce the bearing voltage to prevent the electrolytic corrosion of the bearing by connecting the end cover to the stator core by means of pins. For example, it is the same as the Chinese utility model registration application with the application number 2015202008633.6. However, the above-described electrolytic corrosion preventing structure cannot reduce the capacitance of the bearings on both sides to zero, and cannot completely prevent electrolytic corrosion of the bearings.

  In the second method, the front and rear end covers are connected to each other with a conductive tape or a conductive solution so that the end covers and the bearings have the same capacitance. However, the conductive tape or the conductive solution in such a method is liable to lose its effect, so that the purpose of preventing electrolytic corrosion of the bearing cannot be achieved.

  In addition, in the production of conventional permanent magnet DC motors, both the stator and the rotor adopt a circular automatic press method, so the stator volume is large, waste after punching is large, and While the utilization rate is low, when the stator is wound after the frame is injection molded, the winding space is small and the space for the entrance and exit of the winding pins is small, so the number of windings is small, and ultimately the efficiency of the entire motor is reduced. And the motor efficiency is less than 50%.

  Furthermore, in the process of manufacturing the conventional permanent magnet DC motor, each process is independent of each other, and it is necessary to manually transfer and place between the processes, so that the automation level is low and the labor cost is high.

  The present invention has been made in view of the above-mentioned problems in the prior art, and has a high level of automation, can save labor costs, and further has a high efficiency of the entire motor and a high utilization rate of raw materials.
