Abstract
The utility model provides a rotor of a direct current motor, which comprises a rotor shaft, a rotor yoke, magnetic steel and a thrust module seat. The rotor yoke is sleeved at the middle of the rotor shaft, the magnetic steel is embedded on the rotor yoke, and a stainless steel protecting jacket is sleeved outside the magnetic steel. Epoxy resin sealing layers are respectively arranged at the front ends and the back ends of the rotor yoke, the magnetic steel and the stainless steel protecting jacket. The epoxy resin sealing layers are respectively connected with the rotor shaft at a corresponding position in a sealing mode. The thrust module seat is sleeved at the rear of the rotor shaft and is connected with the epoxy resin sealing layers at the back ends. The rotor of the direct current motor is simple in structure, convenient to install and maintain, and used for producing the direct current motor in a solar energy water pump system.
Description
Technical field
The utility model relates to electric machine part, relates in particular to a kind of DC motor rotor.
Background technology
The solar energy water pumping system is owing to involve great expense, and the efficient that therefore improves system is to reduce the best method of system cost.Wherein motor is the core component of whole solar energy water pumping system, and the height of electric efficiency has directly determined the height of solar energy water pump system efficiency.General solar energy water pumping system all adopts common alternating current machine, inefficiency.Also there is peer machine to adopt traditional direct current machine, but complex structure, maintenance and repair are inconvenience all.
The utility model content
The purpose of this utility model is exactly for a kind of DC motor rotor that is used for the solar energy water pumping system is provided, with the DC motor structure complexity that overcomes prior art, the defective of inconvenient maintenance.
In order to achieve the above object; the utility model has adopted following technical scheme: a kind of DC motor rotor; comprise armature spindle, rotor yoke, magnet steel and thrust module base; rotor yoke is sleeved on the middle part of armature spindle; magnet steel is inlaid on the rotor yoke; outside magnet steel, be set with the stainless steel protection cover; rear and front end at rotor yoke, magnet steel and stainless steel protection cover is respectively equipped with the epoxy sealing layer; this epoxy sealing layer links to each other with the rotor shaft sealing of relevant position, and the thrust module base is sleeved on the rear portion of armature spindle and links to each other with rear end epoxy sealing layer.
Described armature spindle is interval with two annulus at the position that links to each other with the sealing of front end epoxy sealing layer, forms a circle groove between two annulus; Described front end epoxy sealing layer links to each other with the nested sealing of this groove.
Described armature spindle is respectively equipped with at its two ends and is used for contacting the chromium coating that links to each other with bearing, and the thickness of this chromium coating is not less than 0.3mm.
The utility model direct current (DC) motor rotor structure is simple, convenient for installation and maintenance, is used to make the direct current machine of solar energy water pumping system.
