Abstract

The invention relates to a motor, in particular to a direct current permanent magnetic upper wheel motor for use in an oil field pumping unit. The direct current permanent magnetic upper wheel motor has a structure that: a stator silicon steel sheet is fixed on a spindle by a stator inner ring locking plate; coil windings are wound on the stator silicon steel sheet; and a permanent magnet is arranged between the stator silicon steel sheet and an outer rotor ring. The invention has the advantages that: the motor is suitable for the power outputs of various lifting machines and replaces the mechanical transmission parts of the conventional lifting machines; the output power of the motor act directly to improve working conditions; zero friction and zero loss of the machines are realized; as mechanical friction and loss are avoided, electric energy is saved by about 40 to 60 percent; the maintenance period is prolonged; and as the repair and maintenance cost of the machines are avoided, the equipment operation cost is reduced considerably.

Description

technical field [0001] The invention relates to a motor, in particular to a DC permanent magnet sky wheel motor used in an oil well pumping unit. Background technique [0002] The pumping unit currently used in oil wells drives the pumping unit to work through the rotation of the sky wheel, but the sky wheel needs to be driven by a motor, which causes mechanical friction and wear, wastes electric energy, inconvenient maintenance, and high equipment operating costs. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a DC permanent magnet sky wheel motor, the purpose of which is to prolong the maintenance period and reduce the operation cost of the equipment. [0004] In order to achieve the above-mentioned purpose, a DC permanent magnet sky wheel motor of the present invention is composed of the following structure: the stator silicon steel sheet is fixed on the main shaft through the stator inner ring locking s...
