1. Reduce the starting current of the motor, reduce the power distribution capacity, and avoid investment in capacity expansion; 2. Reduce the starting stress and prolong the service life of the motor and related equipment; 3. Smooth start and soft stop avoid the surge problem and water hammer effect of traditional starting equipment; 4. A variety of starting modes and a wide range of current, voltage and other settings can be adapted to a variety of load conditions; 5. Perfect and reliable protection function to more effectively protect the safety of motors and related equipment; 6. It can start/stop the motor smoothly without steps, avoiding mechanical and electrical shocks caused by traditional starting methods such as direct starting, star/delta starting, and auto-decompression starting; 7. It can effectively reduce the starting current and distribution capacity, and avoid investment in capacity expansion. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #ac powersoftstarterwithbuilt-inbypass #builtinbypasssoftstarter #softstartcabinet #ZJSHUYI #Chinashuyi

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...

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 #...
