How can I prevent broken shaft problems in my electric motor?
For the analysis of the cause of the broken shaft problem, it should be the principle of preventing the occurrence of the broken shaft problem to reduce and eliminate the stress point and exclude the external factors. From the analysis of the construction characteristics of the shaft, from the de...Read More -
What are the characteristics of winding fault when three-phase motor lacks phase?
Under normal circumstances, the power supply and winding of the three-phase motor are symmetrical, when the power supply is out of phase or the motor is improperly connected, resulting in the motor input voltage is out of phase, it will cause the motor winding to appear regular burn phenomenon, o...Read More -
Why are motors of the same power so different in size？
For motors for different purposes, in addition to the necessary parameters such as power, rated voltage, torque and speed, the matching relationship between the volume of the motor and the supporting equipment space is particularly important, especially for the space to accommodate the motor is p...Read More -
Can the grounding wire of the motor be soaked in water
The ground wire is a safety component of the motor product, and its main role is to connect the motor shell with the ground to protect personal safety and prevent the motor from failure caused by static electricity. GB/T 755 and GB/T 14711 have special provisions for the grounding of the motor, e...Read More -
Why motor rotors are slanted
In order to improve the quality of the motor, in recent years, the motor noise has been included in one of the quality assessment indicators, especially for the motor operating environment and human contact close to the situation, the noise of the motor has become a very important assessment requ...Read More -
Difference between IC611 and IC616 in high voltage motor cooling method
Cooling methods 611 and 616 are two of the more common methods in air-to-air cooled high voltage motors, but what is the difference between the two cooling methods? How to correctly select the cooling method of the motor? This kind of problem makes a lot of motor customers are very confused, moto...Read More -
Advantages and disadvantages of high voltage motor compared with low voltage motor
High-voltage motor It is generally believed that the motor with a supply voltage of 3KV~10KV is called a high-voltage motor. 6300V and 10000V motors are commonly used. Motor power is proportional to the product of voltage and current, so the power of the low-voltage motor increases to a certain e...Read More -
Three speed regulation methods of DC motor
Dc motor is a kind of motor that uses DC power supply, and its working principle is based on the magnetic effect of current and the effect of magnetic field on current. When the DC power supply provides electrical energy to the motor through the brush and commutator, a constant magnetic field is...Read More -
Rationality of motor bearing clearance selection
Motor products with bearings, by the role of the associated components, both in the radial and axial direction are subject to positioning constraints, the end result of which will have an impact on the clearance of the bearing, which is manifested in the initial clearance of the bearing and the d...Read More -
High voltage motor coil insulation
The coil insulation of high voltage motor has a great impact on the service life and economic effect of the motor, which is a problem that every designer and technician must carefully consider. The high-voltage coil can be called the heart of the motor to some extent, which directly determines th...Read More -
The difference between gas explosion protection and dust explosion protection
Explosion-proof motor is a kind of motor that can be used in flammable and explosive places, and does not produce electrical sparks during operation. According to the explosion-proof principle, the motor can be divided into flameproof motor, increased safety motor, positive pressure motor, non-sp...Read More -
Motor cooling mode
Due to the existence of loss during the use of the motor, the temperature continues to rise, if it is not well cooled, it will affect the service life of the motor. The power of the high-voltage motor is generally large, and the value of its loss power is also large, and cooling is especially imp...Read More
