Abstract

The utility model discloses a wound-rotor three-phase asynchronous motor used in a water injection pump. The wound-rotor three-phase asynchronous motor comprises a housing, a stator, a rotor, a spindle and a bearing. The front portion of the housing is connected with a front end cover, and the rear portion of the housing is connected with a rear end cover. The spindle is arranged at central portions of the front end cover and the rear end cover in a run-through manner. The spindle is fixed on the front end cover and the rear end cover through a bearing inner cover and a bearing outer cover. The spindle is fixed through the bearing. The rotor is sleeved onto the periphery of the spindle. The stator is sleeved onto the outer portion of the rotor. The wound-rotor three-phase asynchronous motor is characterized in that the rear end cover is connected with a collecting ring device directly, and the rotor and the stator are provided with an independent wire connection box respectively. The wound-rotor three-phase asynchronous motor of the utility model has advantages of good overload capacity, low noise, low vibration, reliable structure and beautiful appearance.

Description

A kind of water injection pump wound rotor three-phase asynchronous motor

Technical field

The utility model relates to the motor technology field, is specifically related to a kind of water injection pump wound rotor three-phase asynchronous motor.

Background technology

The water injection pump motor special of the special development in oil field, existing ultralow Tibetan, mostly do not have the Frequency Converter Control of passing through, to obtain bigger starting torque and less starting current, and the function of stepless speed control, and can be according to the requirement of load, reach intelligent control, economical operation and purpose of energy saving, the overload capacity of motor is on the weak side, efficient is low, speed governing not steadily, shortcoming such as operational reliability is low.

The utility model content

Technical problem to be solved in the utility model be to overcome the deficiencies in the prior art and a kind of efficient height is provided, overload capacity is strong, noise is low, the water injection pump wound rotor three-phase asynchronous motor of little, the reliable in structure of vibration.

For reaching above purpose, the utility model adopts following technical scheme: a kind of water injection pump wound rotor three-phase asynchronous motor, comprise housing, stator, rotor, rotating shaft, bearing, the anterior front end housing that connects of housing, the rear portion connects rear end cap, the center of front end housing and rear end cap is run through and is provided with a rotating shaft, bearing is fixed on front end housing and the rear end cap by internal bearing cover and bearing end cover, bearing fixing is passed through in rotating shaft, the rotating shaft outer race is provided with rotor, the outer cover of rotor is provided with stator, and described rear end cap directly connects collector machine, and described rotor and stator are respectively equipped with independently terminal box.

As preferably, collector machine is copper collector machine.

As preferably, described stator leading-out terminal is installed temperature detect switch (TDS).

As preferably, described rotor is by the outer connected control system of rotor junction box.

The beneficial effects of the utility model are: the efficient height, overload capacity is strong, noise is low, little, the reliable in structure of vibration, appearance looks elegant.
