定した起動が行われない欠点があつた。 Conventionally, the capacitor run of split-phase starting capacitor motors has been achieved by installing another auxiliary coil and a switch circuit in parallel with the operating capacitor circuit, but this increases the number of terminals and complicates startup operations. It was hot. Additionally, in order to simplify the starting of general capacitor-started motors, there is one in which a capacitor is connected to one auxiliary coil, and a positive characteristic thermistor (hereinafter referred to as a PTC thermistor) is connected in series with the capacitor. However, in this startup the PTC
There was a drawback that stable startup was not possible because the thermistor quickly reached the Kyrie point.

後スイツチ5を切る操作が必要である。 In order to deal with these drawbacks, this invention connects a driving capacitor to the auxiliary coil, a PTC thermistor in parallel with the capacitor, a circuit connected in series with the relay contact, and connects the driving circuit of the relay to the main coil circuit. At the very least, the time required for the PTC thermistor to reach the Curie point was extended by intermittent energization due to relay chatter. As a result, sufficient startup time was obtained and the motor startup was stabilized. In the figure, FIG. 1 shows a conventional split-phase start type motor, where 1 is a main coil, 2 is a first auxiliary coil, 3 is a second auxiliary coil, and the first auxiliary coil 2 has a driving capacitor 4.
However, a switch 5 is connected in series to the second auxiliary coil 3. By turning on the switch 5, a starting current flows through the second auxiliary coil 3, and after starting, the switch 5 is turned off and the motor is rotated by the main coil 1 and the first auxiliary coil 2. but,
This type requires four terminals and requires an operation to turn off the switch 5 after startup.

る。 Fig. 2 shows a capacitor-start type motor, with 1' being the main coil and 2' being the auxiliary coil, with a PTC thermistor 6 and a starting capacitor 4' connected in series to the auxiliary coil 2'. When the motor is started, a large current flows through the auxiliary coil 2' via the starting capacitor 4', and the motor starts. The starting current of the auxiliary coil 2' causes the PTC thermistor 6 to reach the curing point rapidly, which acts as a switch and cuts off the current. This allows the motor to rotate only by the main coil 1'. However, in some cases, it may take at least 10 seconds to start this motor due to the load, but in the above circuit, the PTC thermistor 6 operates rapidly, so sufficient start-up time may not be obtained.

の回路では10秒となる。 This invention solves the above-mentioned drawbacks, and one embodiment is explained in FIG. 3. 1" is a main coil connected in series with the drive coil 9 of the relay 7. 2" is an auxiliary coil and a driving capacitor. The operating capacitor 4'' is connected in series with the PTC thermistor 6' and the normally open relay contact 8 of the relay 7.
The circuits connected in series are connected in parallel. To explain the operation of the above circuit, when the motor is energized, the auxiliary coil 2'', the PTC thermistor 6', and the relay 7
The motor begins to start due to the normally open relay contact 8 circuit. At the same time, the circuit of the main coil 1'' is also energized, so the drive coil 9 of the relay 7 in this circuit is energized. However, because the load on the main coil 1'' is high, the relay 7 does not chatter until the activation is complete. do. During chattering, the normally open relay contact 8 of the relay 7 is also energized intermittently, so during this time, the PTC thermistor 6' is not energized while the contact is open, and is energized only when the contact is closed. becomes. Since the intermittent time until the Curie point of the PTC thermistor 6' is reached is longer than in the case of continuous energization, sufficient start-up time can be obtained even under high loads. In the case of this example, if the required time for startup is 10 seconds, the time for energizing the PTC thermistor by chattering is 0.01 seconds, and if the cycle is set twice every 0.1 seconds, it will take until the PTC thermistor's Curie point is reached. If the total time is 2 seconds, this circuit will take 10 seconds.
(2秒÷0.01秒×0.1秒/2回=10秒)
従つて10秒くらいの起動時間が必要な電動機に
おいてはこの回路は有用である。 (2 seconds ÷ 0.01 seconds x 0.1 seconds/2 times = 10 seconds) Therefore, this circuit is useful for electric motors that require a starting time of about 10 seconds.

て、電動機のコストダウンが計れた。 This invention connects in parallel a circuit in which a relay coil is connected to the main coil and a circuit in which a driving capacitor is connected in series to an auxiliary coil, and a circuit in which a PTC thermistor and a relay contact are connected in series in parallel with the driving capacitor. Since the relay contacts are controlled by the circuit of the main coil, it is possible to extend the time it takes for the PTC thermistor to reach the Curie point using the chatter of the relay, thereby ensuring sufficient start-up time. , we were able to measure the stability of startup. In addition, it was possible to reduce the number of auxiliary coils by one in a split-phase start type capacitor run motor, making the shape smaller and reducing the cost of the motor.
