A permanent magnet transmission device with a forced convection heat dissipation air-cooled cover

Abstract

A permanent magnetic transmission device with a forced convection heat dissipation air cooling mask comprises a motor (1), an axial fan (8), a magnetic conduction disc (6), a permanent magnetic disc (5) and a load device (3) from front to back in sequence. An air gap (12) is formed between the magnetic conduction disc and the permanent magnetic disc, and is controlled by a controller (13), the air cooling mask (2) is arranged between the axial fan and the load device, the axial fan and the magnetic conduction disc are arranged on a driving shaft (9), the permanent magnetic disc and the load device are arranged on a driven shaft (4), and the driving shaft and the driven shaft stretch out of the air cooling mask and are connected with the motor and the load device respectively. The device is reliable in structural design, capable of effectively conducting heat dissipation, simple in structure and free of additionally arranging external devices and power.

Description

technical field [0001] The invention relates to a transmission device, in particular to a permanent magnet transmission device with a forced convection heat dissipation air-cooled cover. Background technique [0002] 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 th...

AI Technical Summary

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.
