Dehydration electric motor with aluminum enamel insulated wire stator winding

Abstract

The invention discloses a dehydration motor which is provided with an aluminum lacquered wire winding. The dehydration motor comprises a rotor, a rotating shaft installed on the rotor, a stator which surrounds the rotor; wherein, the rotor is supported by a front bearing arranged on a front end cover and a rear bearing arranged on a rear end cover; a stator winding of the stator and a wire connecting terminal of the stator winding are surrounded and sealed by insulating materials such as thermoset plastics. As the stator winding and the wire connecting terminal of the stator winding are enveloped by the thermoset plastics to effectively separate the stator winding and the wire connecting terminal of the stator winding from external moisture-laden air, thus solving the problems of corrosion prevention of the aluminum lacquered wire winding and wiped joints and achieving the waterproof purpose at the same time. Besides, the invention utilizes the characteristics that the thermoset plastics is characterized by little deformation, high strength and strong temperature resistance, thus solving the positioning and installing problem of the front and rear end covers on the stator which isenveloped by the plastics and being beneficial to the motor heat radiation and reducing the noise and vibration.

Description

technical field [0001] The invention relates to a motor, in particular to a dehydration motor with an aluminum enameled wire stator winding. Background technique [0002] The application of aluminum enameled wire to the dehydration motor has been studied in our country. However, the traditional motor structure is usually used, that is, the production of the stator winding is usually wound into a coil first, and then the coil is embedded in the stator core slot. Due to the low tensile strength of the aluminum enameled wire, the adhesion of the paint film is worse than that of the copper enameled wire. When inserting wire manually or by machine, the stator winding of the aluminum enameled wire is easily broken or damaged, resulting in many open circuits and short circuits of the stator winding, and the qualified rate is low. Moreover, the aluminum enameled wire is used in the dehydration motor according to the traditional structure, which cannot effectively solve the problem ...
