Description
The utility model relates to electric machines control technology, particularly controller of three-phase AC moment motor.
Three-phase AC moment motor is compared with direct current machine, all has significantly advantage in all many-sides such as using operation, maintenance, mechanical performance.Be widely used in industries such as printing and dyeing, weaving, papermaking, cable, rubber, plastic film at present.But the control of existing three-phase AC moment motor generally is to adopt the three-phase self-coupling to belong to contact to regulate, so troublesome poeration, easily sparking and heating, useful life is short, safeguards inconvenience, and volume is big, floor space is big, is not easy to realize remote control and control automatically.Show that from the characteristic curve of the torque motor that records hardness is very soft, promptly speed regulation is low.When the load torque variation, rotating speed can not adapt to the hardness requirement promptly along with fluctuations, and overload capacity is not enough when low-voltage simultaneously, and the slightly larger motor of the fluctuation of load just blocks, and the shake of coiling tension occurs.
Use upward above shortcomings in order to solve torque motor, a kind of new Moment Motor Controller of industrial active demand is more effectively more to promote the use of torque motor in multiplex's industry field.The purpose of this utility model is exactly the technical scheme that discloses a kind of energy-saving controller of three-phase AC moment motor to society.A kind of new Moment Motor Controller is provided.
The utility model is achieved in that a kind of energy-saving controller of three-phase AC moment motor, by housing, and the housing protecgulum, the housing bonnet, printed wiring board is formed, and it is characterized in that, has switch to show on the housing protecgulum, switch, the output voltage display list, change over switch is regulated turn-knob; The ground connection mouth is arranged, three-phase connection jaws, control power supply wiring mouth on the housing bonnet; Control circuit is arranged, positive current feedback circuit, comparison circuit, amplifier, trigger and voltage negative feedback circuit in the printed board.Form control circuit with three controllable silicons, three controllable silicons are installed in after the torque motor winding, and triangle connects in doing.In control system, also introduce positive current feedback, whole system is constituted a closed-loop system, both improved the characteristic hardness of torque motor, improved torque motor starting performance when low pressure again, improve overload capacity, enlarge the scope of application of torque motor.In the widely different road of control, comparing element, amplifier and three circuit of trigger have been adopted.
Realization of the present utility model, a kind of employing electrical adjustment is provided, contactless wearing and tearing, the Moment Motor Controller of voltage-regulation smooth start superior performance, have that volume is little, in light weight, efficient is high, heating is little, easy to maintenance by adorning, advantages such as long service life are a kind of desirable Moment Motor Controller.
