Abstract

The invention discloses a built-in oil pump motor. The built-in oil pump motor comprises a stator iron core and a rotor and is directly arranged in an oil pump, wherein windings and a connection line are arranged on the stator iron core, the stator iron core is formed by welding and laminating a group of stator punching sheets with stator grooves, the rotor is formed by aluminum-casting and lamination of a group of rotor punching sheets with rotor grooves, rotor end rings are respectively arranged at two ends of the rotor, a temperature sensor is arranged between the windings, and coils of the windings are formed by winding composite enameled wires. The oil pump motor is not provided with an enclosure and is directly arranged in the oil pump, thus, the whole structure of the oil pump is compact, and the volume of the oil pump is reduced; and the temperature is pre-buried between the windings, the temperatures of the windings are conveniently monitored and controlled during running of the oil pump motor, so that the safe running of the motor is ensured.

Description

Technical field [0001] The present invention relates to the technical field of motors, in particular to a built-in oil pump motor. Background technique [0002] In large-scale refrigeration systems (central air-conditioning, large-scale cold storage, etc.), refrigerating oil is indispensable during normal operation. For this, cycloid rotor oil pump is a better choice. At present, most cycloid rotor oil pumps rely on external motors. Drive, the cycloidal rotor oil pump and the motor are independent of each other. The connection and power transmission are realized through couplings or other connection methods, which makes the overall structure of the oil pump loose and takes up a large space, which is not conducive to the design of the overall mechanical equipment; the oil pump and the motor have an intermediate The connection affects the coaxial accuracy and transmission efficiency between the two, and is prone to noise. [0003] Chinese patent CN2013203252503 discloses an internal...
