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 runs smoothly. This is the so-called soft start of the electric motor. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #ac powersoftstarterwithbuilt-inbypass #builtinbypasssoftstarter #singlephasemotorsoftstarter #ZJSHUYI #Chinashuyi
