Selection of commonly used lubricating grease for motors
The purpose of lubrication is to reduce friction and wear; Lubricating oil can also take away the heat generated by friction, thereby reducing the temperature of the friction surface and playing a ...
The five most common ways of starting motors
1. Full pressure direct start When both the grid capacity and load allow for full voltage direct start, full voltage direct start can be considered. The advantages are convenient operation and con...
What will happen if the motor loses phase current?
When a three-phase motor lacks one phase of electricity, an effective magnetic field cannot be formed inside the motor, which can quickly burn out the motor. What is the specific reason for the lac...
What is the difference between a variable frequency motor and a regular motor?
Variable frequency motor, also known as variable frequency speed control motor, controls the motor through a frequency converter. In fact, besides being a variable frequency motor itself, three-pha...
Reasons for motor overheating
1. The power supply voltage is too high or too low, and excessive current causes the winding to heat up 2. Improper use of hot dismantling method during repair and dismantling of windings can burn...
Reasons and solutions for overheating of motor bearings
1. Incorrect installation of rolling bearings, tight or loose fit tolerances 2. Heating problem caused by unsuitable lubrication system 3. The axial clearance between the outer bearing cover of the...
