Coiling together, the active force coil turn are less than described auxiliary powered coil the number of turns；
The active force coil and the auxiliary powered coil are connected by switch dividing device with the extraneous power supply；
The switch dividing device includes level-one master switch and second level selection switch, and the level-one master switch is arranged described
Between active force coil first end and the extraneous power supply；
The active force coil second end is connected with the auxiliary powered coil first end, the second level selection switch setting
Between the active force coil second end and the auxiliary powered coil second end.
Further improve is that the switch dividing device is equipped with auxiliary switch, and the auxiliary switch is arranged in institute
It states between active force coil second end and the auxiliary powered coil first end.
Further improve is that the auxiliary switch and the second level select switch to integrate for auxiliary control switch.
Further improve is that the auxiliary control switch is started by delay device.
Further improve is that the level-one master switch and auxiliary control switch are equipped with joint reset unit.
Further improve is that the active force coil turn is equal to auxiliary powered coil the number of turns a quarter.
Further improve is that the active force winding wire diameter is equal to the four of the auxiliary powered coil diameter of wire
Times.

Due to using above technical scheme, the beneficial effect for having it is the utility model：
The second level starting motor of the utility model passes through active force coil when starting by the way that auxiliary powered coil is arranged
The demand to starting current is reduced with the series connection of auxiliary powered coil.To solve electric motor starting electric current mistake in the prior art
Big problem.
Detailed description of the invention
Fig. 1 is that a kind of second level of the utility model starts the structure connection diagram of motor.
Specific embodiment
In order to realize utility model technological means, create feature, reach purpose and effect is easy to understand, below
In conjunction with attached drawing, the utility model is further described.
A kind of second level that the first embodiment of the utility model provides starts motor, as shown in Figure 1, second level starts motor packet
Rotor, stator, magnet exciting coil are included, magnet exciting coil is connected with extraneous power supply 1.Magnet exciting coil includes active force coil 2 and auxiliary dynamic
Line of force circle 3, active force coil 2 and auxiliary powered coil 3 accompany coiling, and 2 the number of turns of active force coil is less than auxiliary 3 the number of turns of powered coil.
In order to facilitate using and coiling, preferable the number of turns is that main 2 the number of turns of powered coil is equal to auxiliary 3 the number of turns a quarter of powered coil, phase
2 diameter of wire of active force coil answered is equal to four times of auxiliary 3 diameter of wire of powered coil.
Active force coil 2 and auxiliary powered coil 3 are connected by switch dividing device with extraneous power supply 1.Switch distribution dress
It sets and selects switch 6 to integrate for auxiliary control switch pass including level-one master switch 4, auxiliary switch 5 and second level.Level-one master switch 4 is set
It sets between 2 first end 21 of active force coil and extraneous power supply 1.2 second end 22 of active force coil and 3 first end of auxiliary powered coil
31 are connected by auxiliary switch 5, and second level selects switch 6 to be arranged in 2 second end 22 of active force coil and auxiliary powered coil 3 second
Between end 32.
In addition, to avoid short circuit when inductive effect, active force coil 2 and 3 both ends of auxiliary powered coil are connected to buffering
Capacitor 7.
Start to automate auxiliary control switch by delay device, i.e., it is auxiliary in the set time after level-one master switch 4 starts
Control switch is automatically starting, and delay device can be realized by electronic counter or mechanical counter.In order to avoid level-one is total
After switch 4 is closed, auxiliary control switch cannot play a role, level-one master switch 4 and auxiliary without restoring reset condition in starting next time
Control switch is equipped with joint reset unit.
In use, being first turned on level-one master switch 4, after motor start-up, auxiliary control switch can manually or automatically start,
Motor enters normal operating conditions in this way.When motor is closed, level-one master switch 4 is closed, since joint reset unit auxiliary control is opened
It closes to reset and waits starting next time.
The utility model passes through active force coil and auxiliary powered coil string when starting by the way that auxiliary powered coil is arranged
Connection is reduced the demand to starting current.To solve the problems, such as that electric motor starting electric current is excessive in the prior art.
The specific embodiment of utility model is described above.It is to be appreciated that utility model is not limited to
