ZJSHUYI The difference between soft start and hard start of electric mot...

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. The reason why the shaft of the motor is very thick is actually because there was no soft start in the past, and the sudden overload of 5-6 times the starting impact torque of the motor brought by the hard start will break the motor shaft. This is one of the reasons why the motor shaft is designed to be thick. For low-power motors, although the current is large when starting directly, the shock torque at startup is very large for the motor, but the mechanical strength and shock resistance can still be tolerated. For high-power motors, there is a problem. The overload shock caused by the startup, the strength and capacity design of the machine and electricity are all very difficult. And cause a lot of additional costs. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #ac powersoftstarterwithbuilt-inbypass #builtinbypasssoftstarter #singlephasemotorsoftstarter #ZJSHUYI #Chinashuyi
