How to solve the motor burnt problem?


A new client from Indonesia inquiry a vibratory sifter diameter 1500mm, single layer, 16 mesh,

Material: salt, about 90 degree,
Location: Gresik, Indonesia
His existing vibrator of vibration sifter always burn every 1 month, if blower added, it will burn every 2 month, maximum 3 months.

Regarding the motor burnt, there are mainly 2 reasons:
1. Out of lubricating oil, the bearing lock.
2. High temperature operation condition, the wire burnt.

After discussion with client about how to handle the burnt motor, he said, replace the wire coil, if need replace the bearing also. we find the wire coil broken is the main season.
To extend the vibrator/engine service life, we propose the client
1. The motor installed outside, not inside the base.The motor drives the excitor to generate exciting force.
2.Meanwhile we adopt insulation class F instead of regular B, to improve the heat-resistant temperature of the motor, and use heat-resistant lubricating oil.
3. If possible, try to reduce the operation temperature.

Reducing downtime for maintenance can not only reduce production costs but also improve production efficiency.
