Abstract
The utility model discloses a wound-rotor three-phase asynchronous motor used in an oil pumping unit. The wound-rotor three-phase asynchronous motor comprises a housing, a fan, 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 bearing is fixed on the front end cover and the rear end cover through a bearing inner cover and a bearing outer cover. The outside of the front end cover bearing inner cover is provided with a fan cover. The spindle is fixed through the bearing. The fan is sleeved into the inside of the spindle fan cover partially. The rotor is sleeved onto the periphery of the spindle. The stator is sleeved onto the outer portion of the rotor. 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, in the case that a rotor winding is operated when being externally connected with a frequency control device, the original equipment matching type high-power squirrel-cage motor can be replaced with the present project product with a low power, so that the purpose of oil pumping unit system energy conservation can be realized.
Description
Technical field
The utility model relates to the motor technology field, is specifically related to a kind of used for oil extractor wound rotor three-phase asynchronous motor.
Background technology
Use maximum energy consumption equipments as the oil field, the load characteristic of beam pumping unit is cycling alternating load, and load variations is big, and torque amplitude is big.For guaranteeing its breakdown torque, the general service Y that selects for use at present series cage rotor motor equivalent load rate is low excessively, often is in the non-economy running status of " low load with strong power ", causes the significant wastage of the energy.
