Whether our mechanical equipment can work normally, a very important part is whether the motor can run normally. Therefore, motor maintenance is also very important. Many people do not pay attention to maintenance or do not know how to maintain it. W...
The inspection of the motor protection system mainly includes the overcurrent setting of various overcurrent protection devices; the correct action of fast fuses and fast switches various overvoltage protection facilities (such as lightning arresters...
The search for the coupling of the motor is one of the important tasks of the motor installation. The purpose of the alignment is to make the center lines of the two axes of the driving shaft and the driven shaft on the same straight line when the mo...
Single-phase motor failure phenomenon: no rotation after power-on check: The motor winding has three taps. Use a multimeter to measure the resistance between any two. It is found that one of them (red) is disconnected from the other two. Cause...
The performance of the motor should meet the requirements of the working environment around the liming motor. The location, size and quality of the foundation of the liming motor, anchor bolt holes, channels, holes, embedded parts and cable du...
The items that the motor wiring should be checked and the requirements reached by the wiring are as follows: (that is, the precautions to be taken when two motor wiring events occur) 1. Mark clearly and easily distinguish when removing the wir...
Motor rotor assembly inspection items: 1 Appearance quality The surface of the sample is smooth without scratches, rust, burrs, or burrs. The surface of the rotor wheel should be coated with anti-rust paint. The lines of magnetic force are cle...
The main performance of the motor is divided into: one is the starting performance; the other is the running performance: Starting performance: starting torque, starting current. Generally, the greater the starting torque, the better, and the ...
