soft starter mass production



A soft starter continuously controls the motor's voltage supply during the start-up phase. This way, the motor is adjusted to the machine's load behavior. Mechanical operating equipment is accelerated smoothly. This lengthens service life, improves operating behavior, and smooths work flows.

The difference between soft start and hard start of electric motor. www....

Direct start is hard start. The starting current of hard start (direct start) is 3-7 times of the rated current of the motor. In the case of direct start (hard start), the situation of exceeding the rated current of the motor brings many restricted problems to the manufacturing process and structure of the motor itself. Because of this, people started brainstorming to solve this problem and invented soft start. Soft start, as the name suggests, is not to start directly, but to start slowly and little by little. For example, at the input end of the motor, the voltage is gradually increased from 0 to the rated voltage, and the frequency is gradually changed from 0 to the rated frequency, so that the starting current of the motor during the starting process is changed from the uncontrollable overload impulse current in the past. It becomes a controllable starting current that can be adjusted as needed. There is no impact torque in the whole process of starting the motor, but it starts and...

During the starting process of the soft starter motor, the conduction angle of the thyristor gradually increases, the output voltage of the thyristor also gradually increases, and the motor accelerates from zero until the thyristor is fully turned on and the start is completed, thereby realizing the stepless smooth start of the motor. The maximum starting torque and starting current of the soft starter motor can be set according to the load. The main composition of the soft starter is a three-phase parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. Different methods can be used to control the conduction angle of the three-phase parallel thyristor, so that the input voltage of the controlled motor changes according to different requirements, and different functions can be realized. Soft starters and frequency converters are two completely different products. The frequency converter is used where speed regulation i...

ZJSHUYI The reason why the soft start of the motor cannot protect. www.s...

If the soft start of the motor cannot protect, it means that your parameter setting is unreasonable, or even the function setting is wrong. 1. Soft start is used to start the motor to prevent too much starting current from impacting the power grid when starting. The soft-start device is only active during the start-up process. 2. Motor burning prevention is the responsibility of the motor's overload protection device. The simplest fuse is generally a thermal resistance. But the general soft starter can be achieved. 3. The motor still burns, indicating that your circuit design is unreasonable. The configuration of the device is not reasonable. Or not consider overload protection at all. I thought that as long as it was installed, it would provide overload protection. In fact, it needs to be debugged first. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #...
