IEC IP55 Motor

IEC IP55 Motor

This series iec ip55 YRKK710 motor is winding rotor three-phase asynchronous motor, which can adjust starting torque and starting current through adjust rotor external connected additional resistance. Motor proper adopts box-type steel plate welding structure with light weight and good rigidity. This series of motor has advantages of compact structure, light weight, high efficiency, energy-saving, low noise and vibration, high reliability, long service life and convenient installation and maintenance, etc. The motors can operate when ambient temperature is -15℃~+40℃; the altitude ≤1KM; and monthly average air humidity ≤90% (If temperature is 25℃).

Description

Technical Parameters

Brief Introduction

 

YRKK710 IEC IP55 protection motor is a wound-rotor three-phase asynchronous motor.

Protection class IP55 means: protection against external objects and dust, complete protection against the intrusion of external objects, although not complete protection against the intrusion of dust, but the amount of dust intrusion will not affect the normal operation of the appliance; protection against immersion in sprayed water, anti-low-pressure spraying of water that lasts for at least 3 minutes.

 

IP protection level is composed of two numbers, the first number indicates that the electrical dust, to prevent the intrusion of foreign objects level (here referred to as foreign objects including tools, human fingers, etc. can not be contacted within the electrical part of the electrically charged, to avoid electric shock), the second number indicates that the electrical protection against moisture, water immersed in the degree of confinement, the larger the number indicates that the higher the level of protection.

 

6 dust closed cabinet in the 20 mbar low pressure should not enter the dust. In this level of protection can completely prevent the intrusion of foreign objects, although not completely prevent the intrusion of dust, but the amount of dust intrusion will not affect the normal operation of the appliance, and at the same time can prevent the immersion of spray water, anti-low-pressure water spray that lasts at least 3 minutes. The protection level is often expressed as IEC IP55 followed by two numbers, which are used to specify the level of protection.
