Abstract
The utility model discloses a single-phase motor adjuster, comprising an automatic follow controller, a pulse trigger, and a voltage and power regulator. The automatic follow controller is a positive feedback inverse-phase automatic follow controller which is constructed of current signal detection, electric level exchange, synchronous rectification, synchronous integral and synchronous amplification. The utility model can keep operating at the lowest power consumption so as to inhibit the additional loss effectively.
Description
[technical field]
The utility model is about a kind of regulex, especially relates to a kind of motor that can keep at the optimum operation regulex.
[background technology]
Present Do type, Bo type, Co type complete series single phase alternating current (A.C.) asynchronous motor all are not provided with the adjuster of automatic Regulation, and electric drilling match power is excessive, ordinary circumstance empty load of motor rate height, and motor still turns round with rated voltage when unloaded, make the capacity of idle power exorbitant expenditure, the also corresponding increase of the failure rate that supplementary load loss and temperature rise cause.
Therefore, prior art is improved, provided a kind of motor that makes to remain on minimum power consumption operation, the monophase machine adjuster that can efficiently suppress supplementary load loss is real in necessary.
[utility model content]
The purpose of this utility model be design a kind of make motor 100% and following arbitrary load rate district be the minimum power consumption in district and move, power input to a machine equals the power of output shaft acting substantially, the monophase machine adjuster that can efficiently suppress supplementary load loss, and motor is constant in any load factor district and former district power factor, and rotating speed is a rated speed.
To achieve these goals, the utility model adopts following technical scheme:
A kind of monophase machine adjuster is provided, it comprises automatic following controller, pulse trigger, pressure regulation power regulating eqiupment, and this automatic following controller is the anti-phase automatic following controller of positive feedback that is made of current signal detection, level translation, default given, synchronous shaping, synchronous integration, amplification synchronously.
This monophase machine adjuster has also been set up the motor overload protection, fault shows and harmonic wave suppresses circuit.
Motor load changes, electric current changes, by current transformer detect the current level signal, through being transformed to voltage signal level, through default given comparison, shaping synchronously, through integration, anode and master control power positive end are synchronous synchronously, negative terminal send synchronizing amplifier to make synchronous amplification signal, amplify the control impuls trigger synchronously a series of start pulse signals take place, control thyristor operating angle size, thereby auto-control power input to a machine.
Compared with prior art, the utility model has following beneficial effect:
The utility model monophase machine adjuster is followed the regulation and control motor automatically and is in the operation of the highest mixed economy Operational Zone forever, and arbitrary load rate district all is district's lowest limit operation power consumption.When load-rate of motor mc is 20%, can save meritorious and capacity of idle power each 80%; When load factor mc is 80%, can save meritorious and capacity of idle power 17～27%; Improve the starting characteristic and the operation characteristic of motor, reduced electric machine temperature rise greatly.

[embodiment]
See also Fig. 1; the utility model monophase machine adjuster theory diagram; it comprises current level detection, level translation, default given, synchronous shaping, integration, amplifies synchronously; pulse trigger pressure regulation power regulating eqiupment; and overload protection, fault show, harmonic wave suppresses circuit etc., and whole device is series in the electric motor loop.
See also Fig. 2, the utility model monophase machine adjuster schematic circuit is by rectifier diode D
