Embodiment Construction

[0010] Below in conjunction with accompanying drawing this patent is further described

[0011] A high-current lead wire structure of a wound rotor motor, including several layers of soft-state copper skin 1, imide film 2, silicone rubber self-adhesive tape 3, polyester glass tape 4, the soft-state copper skin 1 is selected according to the maximum current-carrying requirements of the rotor The number of layers, the outer cross half of the soft state copper skin 1 is covered with imide film 2 and silicone rubber self-adhesive tape 3, the number of coating layers is selected according to the ground pressure requirements; After ground insulation, a layer of epoxy self-drying paint 5 is coated on the outside; the end of the lead wire structure is plated with a tin-plated layer 6, and an inner hole 7 is provided for connection. The invention effectively improves the reliability of the motor, reduces the cost of materials, and has good process operability.

Abstract

A large current pin structure of a coil wound rotor motor comprises a plurality of layers of red copper sheets which are in a flexible state, a imine film, a silicon rubber self-adhesive tape and a fiber glass tape, half block of crossed flexible red copper sheets wrap the imine film and the silicon rubber self-adhesive tape, and the fiber glass tape is wrapped in an upper block of the flexible red copper sheets, and a layer of epoxy self- dried lacquer is coated on the fiber glass tape. The large current pin structure of the coil wound rotor motor replaces utilization of the prior copper core rubber insulating leading and connecting wires in a parallel connection mode, and the problems that the current-carrying is big, and insulating rubber of the wire is prone to aging and short in insulating service life are effectively solved. The large current pin structure of the coil wound rotor motor has the advantages of being low in cost, high in reliability, convenient to operate and the like.

Description

technical field [0001] The invention relates to the field of motors, in particular to a large current lead wire structure of a wound rotor motor. Background technique [0002] The winding rotor of the motor has a large current when it is started, fully loaded and overloaded, especially the design power and torque of the wound rotor motor are large, which requires that the conductor connected to the slip ring of the motor rotor can carry large currents. Most of them use copper core rubber insulated lead wires, whose effective cross-section is affected by the outer diameter and uses multiple parallel connections, and is limited by the through-hole cross-section of the lead shaft diameter. Contents of the invention [0003] The purpose of the present invention is to provide a large current carrying structure, small cross-sectional area, high insulation withstand voltage, and good heat dissipation effect of a wound rotor motor with a large current lead wire structure, so that ...
