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...

The so-called #softstart means that the voltage we add to him at the beginning of the start is lower than the rated voltage. Common #softstart are: soft starter start, autotransformer step-down start. Autotransformer step-down start-up In the early stage of starting the motor, first add a voltage of 60% to 80% of the rated voltage to it, let it move first, and then switch it to work under the rated voltage after it starts to rotate. It is a simple #softstart process. The soft starter is more advanced than the autotransformer step-down start. The principle is the same. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #bestacfrequencyinverter #generaltypefrequencydrive #3phasefrequencyinverter #variablespeeddrivefrequencyinverter #frequencyinvertervfddrive #frequencyinverterforsale #minifrequencyconverter #highefficiencyfrequencyinverter

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...
