AI Technical Summary
The bilateral surface-mounted cooling structure of the existing ultra-precision linear motor causes the side temperature to increase, which easily causes heat exchange with the environment, making it difficult to meet the constant temperature requirements for the ambient temperature.
A copper foil thermal conductive ring is installed on the outer surface of the winding and fixed with structural glue to increase the heat conduction path, direct the heat from the side of the winding to the cooling plate, block the heat from being released to the outside through the side of the motor, and achieve thermal shielding.
It effectively suppresses the temperature rise of the winding, increases the thrust density, reduces the heat exchange between the motor and the outside world, ensures the precise position detection conditions of the motor, and does not change the volume of the motor.
