Problems solved by technology
[0002] When the shielded electric pump in the prior art transports low-temperature medium, the medium enters the motor cavity, causing the motor temperature to be low, forming a large temperature difference with the surrounding environment, and condensation occurs, resulting in icing of the motor shell and condensation outside the junction box; the motor shell Repeated freezing and melting will cause damage to the motor casing, and dew condensation in the junction box will lead to a decrease in insulation, and even a short circuit caused by leakage; Technical solution, this solution not only increases the production cost, but also increases the difficulty of installation, but still does not solve the fundamental problem

The invention discloses a motor for shielding an electric pump. The motor comprises a casing, wherein a center shaft is arranged in the casing and is sequentially sleeved with a stator assembly and a rotor assembly; a stator shielding sleeve is arranged on the inner surface of the stator assembly; a rotor shielding sleeve is arranged on the outer surface of the rotor assembly; a connecting box is arranged on a side wall of one side of the casing; and the axis of the connecting box is arranged in the radial direction of the casing. By the technical scheme disclosed by the invention, when the shielded electric pump transports a low-temperature medium, the low-temperature medium enters a motor chamber and carries out heat exchange with the heat generated by heating of the motor stator assembly, so that a temperature difference is also reduced while an over-high temperature of the motor stator assembly is reduced, and icing outside the motor casing caused by condensation is avoided.
Description
technical field [0001] The invention belongs to the field of air conditioner manufacturing, and more specifically, the invention relates to a motor used for shielding electric pumps. Background technique [0002] When the shielded electric pump in the prior art transports low-temperature medium, the medium enters the motor cavity, causing the motor temperature to be low, forming a large temperature difference with the surrounding environment, and condensation occurs, resulting in icing of the motor shell and condensation outside the junction box; the motor shell Repeated freezing and melting will cause damage to the motor casing, and dew condensation in the junction box will lead to a decrease in insulation, and even a short circuit caused by leakage; Technical solution, this solution not only increases the production cost, increases the difficulty of installation, but still does not solve the fundamental problem.
