Background technology
Capacitor start motor generally includes the stator of being made up of main winding and auxiliary winding and running electric capacity.Wherein auxiliary winding also can be worked when motor normally moves except that playing priming, so the auxiliary winding of capacitor start motor generally includes starting circuit and operation circuit.The auxiliary winding of traditional capacitor start motor copper cash commonly used or aluminum steel, and the number of turn of auxiliary winding fixes, thus moment is little when making the starting of motor, and run time behaviour is unstable.
Summary of the invention
The purpose of the utility model provides a kind of starting circuit structure of capacitor start motor of the flexibly changing motor auxiliary winding number of turn.
For realizing above-mentioned purpose; The starting circuit structure of the utility model capacitor start motor; It comprises the stator that is composed in parallel by the main winding and first auxiliary winding, and the output of first auxiliary winding is connected with running electric capacity, also is connected with second auxiliary winding between the said running electric capacity and first auxiliary winding; The input of first auxiliary winding is connected with the contact, and output is connected with switch; The input of second auxiliary winding is connected with switch, and output is connected with the contact; When electric motor starting, the switch of the first auxiliary winding output is connected with the input end switch of second auxiliary winding, first auxiliary winding and the series connection of second auxiliary winding; When motor moves, the switch closure on the contact on the first auxiliary winding input and the second auxiliary winding input, the closing of contact on the switch on the first auxiliary winding output and the second auxiliary winding output, first auxiliary winding forms parallelly connected with second auxiliary winding.
Be provided with fixed contact between said first auxiliary winding and second auxiliary winding, when electric motor starting, the switch on the switch on the first auxiliary winding output and the second auxiliary winding input is closed with fixed contact respectively.
Adopt the starting circuit structure of the utility model capacitor start motor,, can adjust the number of turn of auxiliary winding flexibly according to the demand of different times in the motor operation course; When electric motor starting, first auxiliary winding and the series connection of second auxiliary winding, the auxiliary winding number of turn is many, and starting torque is big, the motor normal starting; When motor moves, the parallel connection of first auxiliary winding and second auxiliary winding, the auxiliary winding number of turn is few, makes the running electric capacity voltage can be not too high, the auxiliary winding operate as normal, motor performance is stable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
The starting circuit structural representation of capacitor start motor when Fig. 1 is the utility model electric motor starting;
The starting circuit structural representation of capacitor start motor when Fig. 2 moves for the utility model motor.
Embodiment
Like Fig. 1 or shown in Figure 2; The starting circuit structure of the utility model capacitor start motor; It comprises the stator that is composed in parallel by the main winding 1 and first auxiliary winding 2, and the output of first auxiliary winding 2 is connected with running electric capacity 3, and said running electric capacity 3 and 2 of first auxiliary winding also are connected with second auxiliary winding 4; The input of first auxiliary winding 2 is connected with contact A, and output is connected with switch 6; The input of second auxiliary winding 4 is connected with switch 5, and output is connected with contact B; When electric motor starting, the switch 6 of first auxiliary winding, 2 outputs is connected with the input end switch 5 of second auxiliary winding 4, first auxiliary winding 2 and 4 series connection of second auxiliary winding; When motor moves; Switch 5 closures on contact A on first auxiliary winding, 2 inputs and second auxiliary winding, 4 inputs; Contact B on switch 6 on first auxiliary winding, 2 outputs and second auxiliary winding, 4 outputs is closed, and first auxiliary winding 2 forms parallelly connected with second auxiliary winding 4.
Said first auxiliary winding 2 and 4 of second auxiliary winding are provided with fixed contact 7, when electric motor starting, the switch 5 on switch 6 on first auxiliary winding, 2 outputs and second auxiliary winding, 4 inputs respectively with fixed contact 7 closures.
Adopt above structure, be provided with second auxiliary winding 4 at first auxiliary winding 2 and 3 of electric capacity of running, when electric motor starting; As shown in Figure 1; First auxiliary winding 2 and 4 series connection of second auxiliary winding, the switch 6 of first auxiliary winding, 2 outputs is connected with the input end switch 5 of second auxiliary winding 4, and the auxiliary winding number of turn is many; Thereby the increase starting torque makes the motor normal starting.
When motor moves, as shown in Figure 2, first auxiliary winding 2 and 4 parallel connections of second auxiliary winding; Promptly the contact A of first auxiliary winding, 2 inputs is connected with the switch 5 of second auxiliary winding, 4 inputs, and the switch 6 of first auxiliary winding, 2 outputs is connected with the contact B of second auxiliary winding, 4 outputs, thereby reduces the number of turn of auxiliary winding; If because in the operation process, the auxiliary winding number of turn is crossed and is made running electric capacity 3 voltage too high at most, and the auxiliary winding current density is excessive; Auxiliary winding is prone to burn, and influences machine operation; So in the motor operation course, the contact parallel connection at first auxiliary winding 2 and second auxiliary winding, 4 two ends can make motor performance stable.
