Ideal electric hoist motor protection

Ideal electric hoist motor protection

Motors,  Wire rope hoist  one of the most important components, the use of decision hoist motor life, so for some of the general motors are equipped with protective devices, because insulation technology continues to evolve, both in the design of the motor requires increased efforts, reduce the volume required to make new electric hoist motor is getting smaller and smaller thermal capacity, the load is increasingly weak, and then due to the production increased automation, requiring the motor frequently run in the frequent starting, braking, reversing and variable load variety of ways, for motor protection devices put forward higher requirements.
Traditional  rope hoist  motor protection devices as "thermal relay," which, but the thermal relay low sensitivity, error, poor stability, protection is not reliable. The motor damage and affect normal production of the phenomenon is still widespread.
Ideal motor protection is not the most versatile, but not so-called art, but should meet the actual needs of the scene, so that the unity of economy and reliability, with high cost. According to the actual situation of the scene selection  lift hoist  motor protection type, taking into account the protection of installation, adjustment, easy to use and so on.
