The current required to start the motor is about six times the rated current. At such currents, the motor will be subjected to greater shock than normal operation. Such an impact will increase the loss of the motor, reduce the life of the motor, and even cause damage to other parts inside the machine when the current is too large.

The current required to start the motor is about six times the rated current. At such currents, the motor will be subjected to greater shock than normal operation. Such an impact will increase the loss of the motor, reduce the life of the motor, and even cause damage to other parts inside the machine when the current is too large.
The research on the soft start of the motor is mainly to control the start of the three-phase asynchronous motor. The soft start of the motor is realized by the use of the three-phase asynchronous motor to protect the start and stop of the motor. Such technology is widely used in the industrial field, and the industry has used this technology to replace the traditional Y/â–³ start-up, and has achieved good results.
The principle of motor soft start is as follows:
1. When the click is started, the voltage inside the thyristor gradually rises, and the motor will slowly accelerate under the action of the voltage;
2. When the running speed reaches the required speed, the thyristor will achieve full conduction. At this time, the clicked voltage is the same as the rated voltage, which can achieve the soft start of the motor and the mechanical performance of the machine. Let the whole process run smoothly.
1. Under such circumstances, the motor operates normally under the protection of the thyristor, so that the motor is subjected to less impact and loss, so that the service life of the motor can be significantly improved, and the motor can be kept in a good working state.
The three-phase parallel thyristor (SCR) is capable of regulating the voltage of the soft starter. It is a voltage regulator for the soft starter. When the three parallel thyristors are connected to the circuit, they act as a connection between the power supply and the motor stator.
The thyristor AC voltage regulation soft start is mainly to change the connection mode of the thyristor, and the traditional connection mode is connected to the three-winding, thus realizing the power supply to the thyristor in parallel.
The thyristor soft starter has strong adjustability, so users can adjust the motor according to their own needs, and make the motor start mode more suitable for their needs through corresponding changes.
The soft start can not only greatly reduce the starting shock of the transmission system itself, but also prolong the service life of key components. At the same time, it can greatly shorten the impact time of the motor starting current, reduce the thermal shock load on the motor and affect the power grid. This saves energy and extends the working life of the motor.
By using the soft start technology, a smaller capacity motor can be selected for the selection of the motor, thereby reducing unnecessary equipment investment.
The start of the star triangle is to change the wiring of the motor winding, thus changing the voltage at the start of the motor. The voltage at the start is reduced, the starting current is reduced, the impact on the busbar is reduced at the start, and the voltage drop of the bus voltage at the start of the motor is reached. Within the allowable range (requires the bus voltage drop not to exceed 10% of the rated voltage), the coupling decompression start is also able to reduce the current when the motor starts, which is obtained when the motor is started by the change of the autotransformer voltage tap. The voltage is reduced, so that the current is reduced, reducing the impact on the bus.
