Shaft Sinking Winch Motor is an indispensable power provider in people's production and life. In the process of using, many Shaft Sinking Winch Motors have a very hot phenomenon, but many times they don't know how to solve them. I don't know what caused the Shaft Sinking Winch Motor to heat up. This should be the first thing I learned during the use of Shaft Sinking Winch Motor. Let's take a look at the common causes of why the motor is very hot.
1. Shaft Sinking Winch Motor has a small air gap between the stator and the rotor, which easily leads to the collision between the stator and the rotor.
In medium and small Shaft Sinking Winch Motor, the air gap is generally 0.2mm to 1.5mm. When the air gap is large, the excitation current is required to be large, which affects the power factor of the Shaft Sinking Winch Motor; if the air gap is too small, the rotor may be rubbed or collided. Generally, due to the serious bearing tolerance and the wear and deformation of the inner hole of the end cover, the bottom of the base, the end cover and the rotor cause the broom, which makes it easy for the Shaft Sinking Winch Motor to heat up or even burn. If it is found that the bearing wear should be replaced in time, the end cover is replaced or brushed, and the simpler treatment method is to insert the end cover.
2, Shaft Sinking Winch Motor's abnormal vibration or noise is likely to cause the fever of Shaft Sinking Winch Motor
This situation is caused by the vibration caused by Shaft Sinking Winch Motor itself, mostly due to poor rotor dynamic balance, poor bearing, shaft bending, end caps, base, rotor different shafts, loose fasteners or Shaft Sinking Winch Motor installation. If the foundation is not flat and the installation is not in place, it may be transmitted from the mechanical end and should be excluded according to the specific situation.
3, the bearing work is not normal, it must cause Shaft Sinking Winch Motor fever
Whether the bearing works properly can be judged by hearing and temperature experience.
The bearing end can be detected by hand or thermometer to determine whether the temperature is within the normal range; the bearing rod (copper rod) can also be used to contact the bearing box. If the impact sound is heard, it means that there may be one or several balls crushed, if heard The buzz, that is, the bearing's lack of lubricating oil, Shaft Sinking Winch Motor should be used to change the grease for about 3,000 hours to 5,000 hours.
