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...

AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process. Contactors with a capacity of more than 10A have arc extinguishing devices. AC contactors also have auxiliary components such as reaction springs, buffer springs, contact pressure springs, transmission mechanisms, bases and terminals. The working principle of the AC contactor is to use the electromagnetic force to cooperate with the spring force to realize the connection and disconnection of the contacts. The AC contactor has two working states: de-energized state (release state) and electrified state (action state). When the attraction coil is energized, the static iron core generates electromagnetic attraction, the armature is pulled in, and the connecting rod connected to the armature drives the contact to mov...

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
