Problems solved by technology
The winding of the water-type motor is held firmly by rubber sleeves. The motor runs for a long time, the motor heats up, and the rubber sleeves are easy to soften. After long-term use, the rubber sleeves age quickly, causing the motor to leak electricity; when the shielded motor is running, it is easy to generate a lot of heat, so that the shielding sleeve is easy to expand and contract. In the process of thermal expansion and contraction of the shielding sleeve, water vapor is easily sucked into the shielding sleeve, which will cause the winding in the stator to contact water vapor and cause the motor to leak electricity, and the shielding motor will run for a long time, and the shielding sleeve will also bulge due to thermal expansion. The starting part and the motor rotor will be stuck, and the motor will be burned out; the main reason for the above problems is that the existing water motor and shielded motor are not tight enough to seal the windings, and the existing shielded motor is equipped with a shield set

The invention relates to a direct-shielding motor. The direct-shielding motor is based on an existing structure. A winding (120) in a stator (101) in the existing structure is designed to be composedof a copper wire (121) and waterproof paint (122), a high-temperature film (123) and a rubber sleeve (124) which are sequentially fixed to the outer side of the copper wire (121). The winding (120) isarranged in a winding slot (119) arranged in the stator (101); heat sealing is performed by using epoxy resin (126); due to the design, the motor can be placed in water to work without electric leakage without a shielding sleeve, so that the blocking fault of the shielding sleeve and the rotor (102) is avoided, the electric leakage of the copper wire (121) of the winding (120) is not easily caused through the multi-layer protection design, the service life of the motor is prolonged, and the safety coefficient of an operator is improved.
Description
technical field [0001] The invention belongs to the technical field of motors. Background technique [0002] At present, the motors on the market are basically divided into water motors and shielded motors. The winding of the water-type motor is held firmly by rubber sleeves. The motor runs for a long time, the motor heats up, and the rubber sleeves are easy to soften. The rubber sleeves age quickly after long-term use, causing the motor to leak electricity. When the shielded motor is running, it is easy to generate a lot of heat, so that the shielding sleeve is easy to expand and contract. In the process of thermal expansion and contraction of the shielding sleeve, water vapor is easily sucked into the shielding sleeve, which will cause the winding in the stator to contact water vapor and cause the motor to leak electricity, and the shielding motor will run for a long time, and the shielding sleeve will also bulge due to thermal expansion. The starting part and the motor r...
