Factors Affecting Temperature Rise During Manufacturing

base surface treatment

When the heat loss generated inside the motor is conducted to the surface of the base, it is mainly carried away by the air blowing over the surface of the motor by the fan end. Therefore, in order to effectively control the temperature rise of the motor, the heat dissipation level on the surface of the base should be improved as much as possible, so that the iron shell with strong thermal conductivity and the cooling medium air are in "close contact" as much as possible, or the isolation layer is as thin as possible.

Special attention must be paid to this situation, because each motor manufacturer attaches great importance to the appearance quality. In order to look beautiful and high-grade, the putty and spray paint layer are thicker, so that the surface defects of the shell are indeed compensated, but it affects the The actual heat dissipation performance of the base surface.

Motor Fan Compliance

As the main air pressure component of the self-fan cooling motor, the size and shape of the fan are the key factors determining the temperature rise level. If the blades of the mixed-flow fan with strong variability are accidentally collided or heavily pressed to bend or deform during stacking and handling, resulting in the change of the rotation angle and impact angle of the fan, it will inevitably lead to an increase in the temperature of the motor windings.

From the design point of view, the fans of motors with the same center height and different pole numbers have certain differences. If a small fan is misused, its ventilation and heat dissipation effect will be greatly reduced; on the contrary, if a large fan is misused, it will lead to the deviation of the motor efficiency index. .

Motor fan blades with bidirectional rotation or uncertain rotation direction generally have no directionality, but for motors with fixed rotation direction, the direction of the fan blades must meet the requirements.

Punching quality control

The core loss is one of the five major losses of the motor. The quality of the punching sheet must be strictly controlled to ensure the lamination coefficient. It is mainly controlled from the following three aspects: Punching material. For this requirement, on the one hand, the choice of the silicon steel sheet supplier is to ensure that the material properties are met; For example, W600 silicon steel sheets should be used but W800 sheets are misused. Punching burr control. Most iron core manufacturers can control the punching burr within 0.05mm, which can ensure the lamination effect of the iron core; otherwise, the effective iron weight will be insufficient, the iron core eddy current will increase, and the iron loss and temperature rise will increase. .

Laminated iron cores. After the iron core is laminated, try not to file, grind, process or damage the insulating oxide film. This problem exists in many motor manufacturers. Each motor manufacturer should make substantial improvements to this problem, because the grinding of the iron core will directly affect the performance of the motor. No matter how good the material is, if there is no good production Processing technology, motor quality control and improvement will not be very effective.
