Problems solved by technology
Water-cooled and oil-cooled devices have disadvantages such as high cost, difficult sealing, easy corrosion, and complex structure. However, the current air-cooled heat dissipation mainly relies on its own rotating centrifugal heat dissipation and heat dissipation of heat sinks, and its heat dissipation capacity is poor.

Description
[0001] technical field [0002] The invention relates to a transmission device, in particular to a permanent magnet transmission device with forced convection heat dissipation. Background technique [0003] As a new type of actuator, the permanent magnet actuator is widely used in electric power, petrochemical, steel, pharmaceutical, metallurgy and other industries. The permanent magnet drive is a transmission device that transmits torque through the air gap. There is no mechanical connection between the motor and the load equipment shaft. It is generally composed of a magnet connected to the motor, a permanent magnet connected to the load, and a control box. There is a certain air gap between the magnetic conductor and the permanent magnet. According to the different structures of the magnetic conductor and the permanent magnet, it can be divided into disc type, cylinder type, hybrid type, etc. Taking the disk type permanent magnet actuator as an example, when the motor ro...
