Abstract
The utility model discloses a kind of novel power saving motor, comprise motor 1 and frequency converter 2, described frequency converter and motor are electrically connected, the output shaft of described motor 1 is provided with grating sensor 3, also comprise controller 4 and adjuster 5, described controller is electrically connected with adjuster and frequency converter respectively, and described adjuster and grating sensor are electrically connected.The beneficial effects of the utility model are, energy savings reduces the wastage.
Description
Technical field
The utility model relates to electric motor energy-saving technique application, particularly a kind of novel power saving motor.
Background technology
In motor drive system, often add that allowance comes design parameter and type selecting with most high capacity amount, and in the operation of reality, the motor of considerable part non-full load, but but work in the less state of full voltage, the load of full gear degree.
For the motor that varying load runs, while normal work, also have very large economize on electricity space.Because the change of load can change along with actual demand, and the input power of motor can not adjust, namely usually said " low load with strong power " thereupon.
Can be known by motor designs and operation characteristic, under common motor control model, motor is most effective when full-load run.When relative light running, motor produces the invalid loss of a large amount of electric energy much larger than actual needs value because of input voltage, frequency; Under frequency transducer control mode, motor input voltage, frequency are relatively greater than actual needs value thus produce the invalid loss of corresponding electric energy.
Utility model content
The purpose of this utility model is to solve the problem, and devises a kind of novel power saving motor.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of novel power saving motor, comprise motor 1 and frequency converter 2, described frequency converter and motor are electrically connected, the output shaft of described motor 1 is provided with grating sensor 3, also comprise controller 4 and adjuster 5, described controller is electrically connected with adjuster and frequency converter respectively, and described adjuster and grating sensor are electrically connected.
Described controller 4 adopts the mode of vector control by the output speed of Frequency Converter Control motor.
Described adjuster 5 is the structures connected and composed successively by the filter 7 be fixed in housing 6, electric signal amplifier 8 and A/D converter 9.
Described filter 7 is electrically connected with grating sensor signal output.
Described A/D converter 9 is electrically connected with the signal input part of controller.
The novel power saving motor utilizing the technical solution of the utility model to make, the mode of load to motor self adaptation vector control is had more by controller, adjust power input to a machine in real time, the voltage making motor obtain load instant with it to adapt most, thus ensure that motor runs all the time under maximum energy-saving state, thus effectively save valuable electric energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel power saving motor described in the utility model;
In figure, 1, Electricmotor car wheel; 2, frequency converter; 3, tachymeter; 4, controller; 5, adjuster; 6, housing; 7, filter; 8, analog signal amplifier; 9, A/D converter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as the structural representation that Fig. 1 is novel power saving motor described in the utility model, as shown in the figure, a kind of novel power saving motor, comprise motor 1 and frequency converter 2, described frequency converter and motor are electrically connected, the output shaft of described motor 1 is provided with grating sensor 3, also comprise controller 4 and adjuster 5, described controller is electrically connected with adjuster and frequency converter respectively, and described adjuster and grating sensor are electrically connected.Wherein, described controller 4 adopts the mode of vector control by the output speed of Frequency Converter Control motor; Described adjuster 5 is the structures connected and composed successively by the filter 7 be fixed in housing 6, electric signal amplifier 8 and A/D converter 9; Described filter 7 is electrically connected with grating sensor signal output; Described A/D converter 9 is electrically connected with the signal input part of controller.
The feature of the technical program arranges grating sensor on the output shaft of motor, the size of motor load is monitored by grating sensor, and the signal real-time monitored is transferred to controller by adjuster, described controller passes through the rotating speed of Frequency Converter Control motor by the mode of vector control, and then adjust power input to a machine in real time, the voltage making motor obtain load instant with it to adapt most, reduce electric energy loss, improve the utilance of electric energy, extend the useful life of motor.
In the technical program, controller detects by grating sensor the size that the motor output shaft elastic deformation that itself produces when rotating judges load on output shaft, thus the frequency and voltage of motor is adjusted in real time according to the size of load, control the rotating speed of motor output shaft.
In the technical program, the machinery being converted into load equipment needing to the electrical power of motor input is exerted oneself and loss two parts of motor self.The loss of motor self is damaged by the machinery of " iron loss " of magnet, " copper loss " of wire and bearing friction, fan again and is formed.Controller detects the change of load-rate of motor by grating sensor, and according to the actual demand of load, the input power of adjustment motor in real time, ensures that motor runs under the power save mode of minimum current and optimum voltage.Motor current and minimizing of voltage just can make the “ Tie Damage of motor self " and " copper loss " reduce to minimum, realize reducing the heating of motor while energy-saving run, and greatly extend the useful life of motor.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection range of the present utility model.
