Abstract
The utility model relates to a starting switch of unidirectional asynchronous motor, which is characterized in that a bidirectional thyristor (1) is connected in series with a main winding and a subsidiary winding of the motor respectively and is connected in parallel with a power supply (7); a Hall velometer (2) is connected in series with a signal processor (3) while the signal processor (3) is connected in series with an amplifying trigger (4); the amplifying trigger (4) is connected in series with the bidirectional controlled silicon (1). When the motor speed tested by the Hall velometer (2) is larger than the set value, the bidirectional thyristor (1) connected with the subsidiary winding starts, and then the subsidiary winding (6) is cut off with the power supply (7), therefore the motor starts and operates. The utility model has the advantages of none contact, high reliability, long service life and simple manufacture.
Description
The utility model relates to a kind of starting switch of monopole asynchronous motor.
Single-phase resistance starting, capacitor start and two-capacitance capacitive monopole asynchronous motor all must add a starting switch, the starting switch contact is serially connected in the auxiliary winding circuit, with main winding and be attached to power supply, when rotor speed rises to certain value, starting switch is with the auxiliary winding dump, but two value capacitor motor has only been cut off starting capacitance, and running electric capacity still carries out work.Traditional starting switch all is centrifugal, and when electrical motors arrived rated speed 70-80%, centrifugal was left the contact, the auxiliary winding dump.This switch is owing to be spring structure, and its contact and spring all have service limits, and useful life is limited, is generally 5-10 ten thousand times; Fitted position requires also very high, and assembling is difficult, because of switch fault repair rate height, has influenced the motor mass and the scope of application.
The purpose of this utility model provide a kind of contactless, reliability is high, the life-span is long, make the Hall starting switch of simple single-phase motor.
The technical solution of the utility model: monopole asynchronous motor Hall gate-controlled switch, it is by bidirectional triode thyristor, Hall speedometer, signal processor, amplifying trigger forms, bidirectional triode thyristor respectively with the unidirectional motor master, the auxiliary winding serial connection, sequential circuit is also received on the power supply, the output of Hall speedometer inserts signal processing circuit, the output of signal processing circuit is connected to the amplification trigger, the output of amplifying trigger is connected to bidirectional triode thyristor, and the speed that records when Hall speedometer is during greater than the rotating speed set, the bidirectional triode thyristor action of joining with auxiliary winding, auxiliary winding and dump, main winding works on, and asynchronous motor is finished starting, runs well.
In the utility model, being connected in series the setting speed that moves to the bidirectional triode thyristor of auxiliary winding is the 70-80% of motor rated speed.
Hall element and controllable silicon and motor starting switch phase configuration make the starting method of motor produce new leap; The Hall gate-controlled switch combines by Small Scale Integration, and production technology level is less demanding; Contactless and spring, dependable performance, long service life; Adopt integrated circuit simultaneously, make the construction of switch compactness, easily install, easily adjust, be suitable for batch production and produce in batches.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Fig. 1 is a structure chart of the present utility model
Embodiment: by shown in Figure 1, two bidirectional triode thyristors 1 are in series with the main winding 5 and the auxiliary winding 6 of single-phase motor respectively, again with this two series circuit and receive on the power supply 7.The output of Hall speedometer 2 is connected with the input of signal processor 3, and the output of signal processor 3 is connected with the input of amplifying trigger 4, and the output of amplifying trigger 4 is connected with the control input end of bidirectional triode thyristor 1.Being connected in series the setting speed that moves to the bidirectional triode thyristor 1 of auxiliary winding 6 is the 70-80% of motor rated speed.Begin to rotate after the motor energising, after Hall element is passed to signal processor 3 processing with the rate signal that records, again through amplifying trigger 4 relatively, when if rotating speed reaches the rotating speed (rated speed 70-80%) of setting, the bidirectional triode thyristor 1 that is connected to auxiliary winding 6 disconnects, auxiliary winding 6 quits work, and main winding 5 operate as normal all the time.Circuit design wiring board according to this, Hall element and the welding of other element in the circuit board, it is inboard and be connected on the motor main winding and auxiliary winding that this wiring board is installed in End cover for motor.
