Abstract
The utility model relates to an alternating current energy-saving motor. The utility model is characterized in that the winding of a stator is provided with a main winding and an auxiliary winding with same phase and same polarity; the wire inlet end of the three phase power supply of the main winding is respectively connected with current transformers C and T; the current transformers C and T are connected with the auxiliary winding of each phase in series; the current transformer obtains the induced secondary current to supply for the auxiliary winding to enhance the magnetic field of the iron core. As the magnetic fields of the two windings actuate the rotor to normally operate under the rated power, the super saturated magnetic fields force the current of the main winding to reduce, and then the goal of power saving is achieved. The utility model has large energy saving effect.
Description
The utility model relates to the improvement of alternating current motor, and a kind of AC energy saving electric motor that can produce huge energy-saving effect is provided.
Though the world is big, goods and materials are limited, though the energy is many, exhaust sometimes, and are human as if the energy reasonable energy utilization, and energy savings for the mankind create more wealth, will be one of the science and technology much progress.Electric energy is to use the most a kind ofly in the world today, and motor then is the maximum consumption person of electric energy, if motor is improved, reduces power consumption, will be a great conservation measures.The most use such as present each factory exchanges three-phases, single-phase various motor, and wherein extensive with the three-phase squirrel cage motor use, power consumption is big.
The purpose of this utility model is to reduce alternating current motor power consumption, and a kind of AC energy saving electric motor that can save electric energy is provided.
The technical solution of the utility model is that the stator winding at the alternating current motor of being made up of stator, rotor is provided with corresponding, the main winding of same polarity, two winding main windings of auxiliary winding three phase mains end of incoming cables and is serially connected with current transformer C, T respectively, transformer secondary circuit is connected in series with each auxiliary winding mutually respectively, supplies with auxiliary winding in order to strengthen core field by the secondary current that current transformer obtains responding to.
The utility model embodiment is described further in conjunction with the accompanying drawings.
Fig. 1 is an AC energy saving electric motor winding schematic circuit.
By shown in Figure 1, having decided winding is provided with corresponding, the main winding 1 of same polarity, 2 two windings of auxiliary winding, the A of main winding, B, C three phase mains end of incoming cables are connected to current transformer C, a T respectively, transformer secondary circuit respectively with each mutually auxiliary winding 2 current transformer that is connected be by the motor power (output) size, its output current size is according to power supply size and fixed, and the current transformer secondary current that obtains responding to is supplied with auxiliary winding in order to strengthen core field thus.Its basic principle is such, when motor in the running in the circuit voltage constant substantially, current drain changes with the size variation of load, if give the load that a secondary current can be shared the part source current in addition, reduce power consumption, so the motor stator design of Windings is become two windings of major-minor of same-phase, same polarity, and supply with auxiliary winding in order to strengthen core field by being serially connected in the induction secondary current that main winding power inleting terminal current transformer obtains.When two winding magnetic fields are enough to order about rotor under rated power during normal moving the commentaries on classics, the over-saturation magnetic field that is produced promptly can force main winding current to reduce, because voltage is constant, and like this along with electric current reduces, power that is reduce, thus reach the purpose of saves energy.
To the different capacity motor, made test of many times with the scheme that present patent application proposes, under the situation that does not change the original performance of motor, the comparable present use of power consumption saves 38% with the general motor of constant power.This technology implementation is promoted, and will produce huge energy-saving effect, for the mankind create more wealth.
