Definitions
- Achievements 5 The invention is subject to diagnostics of units, mechanisms and systems, in which case an electric motor is used.
- SIGNIFICANT FOX (DR. 26) 2 and comparing with the values of the previous measurements, we appreciate the possibility of further operation of the installation. All of the listed diagnostic methods for using the electric motor do not allow judging by the power of the unit or 5 hours of power or a malfunction.
- the closest to the claimed invention is the method of patent No. 2213270 "A method of sharing a power source for electrical installations". In this case, the signal is removed from the variable component of the total power supply of the motor by installing the installed voltage-sensitive sensor. The analysis of the frequency and amplitude of the received signal is compared with previously performed measurements. ⁇ vic The descriptions are subject to change due to change.
- the inventive method for diagnosing mechanisms and systems with an electric motor solves the technical problem of detecting a defective node (unit) of a mechanism or system, and also of a power supply S ⁇ s ⁇ b diagn ⁇ s ⁇ i ⁇ i me ⁇ anizm ⁇ v and sis ⁇ em with ele ⁇ iches ⁇ im dviga ⁇ elem s ⁇ s ⁇ i ⁇ in ⁇ m, ch ⁇ izme ⁇ yayu ⁇ chas ⁇ y am ⁇ li ⁇ udn ⁇ y m ⁇ dulyatsii ⁇ eblyaem ⁇ g ⁇ 25 ele ⁇ iches ⁇ im dviga ⁇ elem ele ⁇ iches ⁇ g ⁇ ⁇ a and ⁇ azhd ⁇ y chas ⁇ y m ⁇ dulyatsii izme ⁇ yayu ⁇ depth am ⁇ li ⁇ udn ⁇ y m ⁇ dulyatsii.

- the method allows you to install a defective machine or system independent of any type of electric motor, which is This method also makes it possible to divide defects not only on aggregates, but also on their components. To speed up the diagnostics of the mechanism or the system in this way, it is possible to pre-arrange the volume of the room or the room or the room
- a safety circuit is available for a faulty electric pump.
- ⁇ a ⁇ ig. 3 shows the concept of safe operation of the faultless, and in fig. 4 - a defective conveyor that is subject to movement by a synchronous motor with a resistant, lowering drive and an asterisk in the last stage.
- the modulation frequency is characterized by a defective unit 5 of the mechanism or system, since each unit of the mechanism or system has a separate property of the enclosure of the property or the unit. These units or systems were detected in the process of executing the diagnostic method.
- the power supply is removable for the power supply of the same model as the power supply of the same model.
- the spare parts of the wheels began to be affected by the stationary parts of the appliance.
- the high frequency component of the expansion is the rate of rotation of the unit / s , which is about 40% of the frequency of rotation
- there were signs of amplitude modulation of the seventh frequency of rotation that is, components of the frequency with frequencies - / l
- the phase of the synchronous motor turns out to be modulated by the amplitude and frequency 20 / ⁇ , and frequency /.
- the degree of wear of the circuit is determined by the reduction of the amplitudes of the components at the side of the frequency / ⁇ / ⁇ to the amplitude of the main component /.
- the degree of wear of the asterisk is similar to that of the components of the current, but on the outside parts + / ⁇ ⁇ ⁇ the main component on the frequency /. Other identified defects are hereby acknowledged.
- the 25th engine speed circuit shows that there is also a defect of teeth on the second axle in the consumer, a short-circuit of the primary amperage of the
- Fig. 5 shows the design of the variable-speed component of the engine at a faultless supply of the mains supply.
- the engine is powered by an electrical appliance and, as a result, it does not have to be variable.
- ⁇ dnim of ⁇ asny ⁇ de ⁇ e ⁇ v ⁇ le ⁇ ey yavlyae ⁇ sya ⁇ e ⁇ e ⁇ s shes ⁇ e ⁇ en arising, for example, due to the faster wear of the extenders from the one-sided staple.
- the quick part and the other part of this defect is the second part of the shaft rotation frequency, one of six gears (6).
- a part of variable components of the engine is supplied with a spare part and such a defect.
- ⁇ In the process, a number of the frequency of rotation of the defective shaft is shown, with the largest amplitude being the second.
- the inventive method makes it possible to identify defective nodes and units of a mechanism or system, and also to determine the value of this defect. The reliability of the method is verified by testing.
