Abstract
The utility model relates to a multi-speed energy-saving motor, which is formed by connecting an inductive circuit to a motor, wherein an air break switch and the inductive circuit are in series connection on a circuit, a control switch and two contactors are in parallel connection on the inductive circuit, windings of the motor are in phase mixing connection, and the contactors are controlled bythe inductive circuit and are in series connection with the windings of the motor. The multi-speed energy-saving motor is simple in structure, convenient in use and wide in parameter adjusting range,and obviously reduces noise and end loss.
Description
Technical field
The utility model relates to a kind of power set of oil exploration equipment.
Background technology
Present most of oil pumpers in recovery process, face two problems, the one, in order to guarantee high detent torque, the power of motor coupling is excessive, power factor and efficient are on the low side during operation; The 2nd, need often to transfer ginseng, change jig frequency.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art and how fast energy-saving electric machine is provided.
The technical scheme that the utility model adopted is: how fast energy-saving electric machine, mainly connecting inductive circuit on motor finishes, sky switch of series connection on the circuit, series inductance circuit then, be parallel with control switch on the inductive circuit, be parallel with two contactors with inductive circuit, the winding of motor is that mixed phase connects.
Contactor is controlled by inductive circuit, the windings in series of contactor and motor.
Compared with prior art, the utility model has the advantages that: simple in structure, easy to use, noise and circle decrease obviously and reduce, and transfer the ginseng scope wide.
