Embodiment Construction
[0008] The invention provides a collector ring device for a wound rotor motor. The heat dissipation and carbon dust prevention device for the collector ring assembly of the wound rotor motor according to the invention increases the number of brushes and improves the ventilation structure on the basis of the original collector ring assembly. The sealing structure of the terminal is added to solve the short circuit problem caused by the heat of the collector ring and the carbon powder.
[0009] The collector ring heat dissipation and carbon dust prevention device of the wound rotor motor of the present invention consists of a junction box 1, a collector ring assembly support 2, a brush 3, a conductive ring 4, a lead wire 6, an insulating sleeve 14, a brush rod 8, and a collector ring 9. Fan 10, insulating pipe 11, conductive rod 12, wind cover 13, sleeve 15, and shaft 16; three identical collector rings 9 are tightly sleeved on sleeve 15 through insulating sleeve 14, and are insu...

Abstract
The invention relates to a radiating and anti-carbon powder device of a collector ring component of a motor of a wound rotor, which belongs to the technical field of manufacture of motors. The device comprises a terminal box, a support of the collector ring component, electric brushes, conductive rings, a leading wire, an insulating sleeve, a brush rod, collector rings, a fan, an insulating pipe,conductive rods, a fan cover, a sleeve and a shaft, wherein, the collector rings are sheathed on the sleeve and mutually insulated with the sleeve, each collector ring is provided with the conductiverod and linked with the leading wire of the rotor, the fan is arranged on the flange part of the sleeve, the whole sleeve is sheathed on the shaft, three electric brushes are arranged on three conductive rings, the conductive rings are arranged on the brush rod, the brush rod is arranged on the support, the support is arranged on an end cover of the motor, an air inlet is formed at the upper part, the fan cover is arranged on the outer side of the end part, and an air outlet is formed at the lower part. The device solves the short circuit problem caused by heating of the collector rings and carbon powder, improves the conductive performance of the collector rings of the motor, prolongs the service life of the collector rings of the motor, reduces the using cost of the motor and improves the reliability of operation of the motor.
Description
technical field [0001] The invention belongs to the technical field of motor manufacturing, in particular to a collector ring device of a wound rotor motor. Background technique [0002] The collector ring assembly is a device for drawing out the rotor voltage and current of the wound rotor motor. As the power of the motor increases, the current drawn from the rotor increases, the number of brushes increases, and the frictional resistance and contact resistance between the collector ring and the brushes increase, which makes the collector ring components heat up, the temperature rises, and the worn carbon The powder also increases, which is easy to cause short circuit and combustion, shorten the service life of the slip ring assembly, and reduce the working reliability of the motor. The existing collector ring assembly device cannot meet the needs of motor development. Contents of the invention [0003] The heat dissipation and carbon dust prevention device of the collec...
