How an AC Motor Changes Steering?
Three phase AC motor is one of the common motors in industrial production, and it usually needs to change the direction of rotation during use. This article will detail how an AC motor changes direction and what to look out for. 1. The principle of changing the steering direction of the AC motor ...Read More -
What is Vibration 3 phase motor?
1. Vibration motor structure The vibration 3 phase motor is composed of a special motor and an excitation weight. When the motor is energized and rotated, the excitation block generates an excitation force, and the vertical and horizontal vibration machinery is transmitted through the motor foot ...Read More -
Is it more cost-effective to replace the motor or to re-manufacture it?
Re-manufacturing is a new measure proposed for the elimination of high energy consumption equipment, 3 phase motor re-manufacturing has once become a popular business for many motor producers and repair units, and some units have specially carried out motor re-manufacturing work. With the country...Read More -
Why does the 3 phase motor jitter when it is started or powered off?
In the process of 3 phase motor test, if the voltage regulation or frequency regulation mode is used to start the motor, the starting process of the motor is relatively balanced, on the contrary, when the motor is started according to the normal operating voltage, the motor has a more obvious jit...Read More -
What’s the necessity of moisture-proof heating of motor winding?
Different environmental conditions for the three phase motor protection level requirements are different, suitable for the operation of the motor in water or other liquids, the motor must have effective protective measures for winding, bearings and other parts, general environment operation of th...Read More -
How to control the radial clearance and positioning of bearings, which is more conducive to the guarantee of motor performance?
Three phase motor‘s bearing internal clearance refers to the total distance that one bearing ring can move in radial or axial direction relative to another bearing ring. For the bearing’s clearance, it is necessary to distinguish between the initial clearance before installation and t...Read More -
What’s he relationship between triangle and star connection and its advantages and disadvantages?
The same three-phase motor can be connected by triangle connection, corresponding to low voltage; It can also be connected according to the star connection method, corresponding to high voltage; The high voltage is 3 times the square root of the low voltage. For example, a 380V motor with a trian...Read More -
What measures can effectively reduce motor noise?
3 phase electric ac motor noise includes electromagnetic noise, mechanical noise and ventilation noise, the noise of a motor is basically a combination of a variety of noise, to achieve the low noise requirements of the motor, should be a comprehensive analysis of the factors affecting the noise ...Read More -
High voltage machines have corona generation, why do variable frequency motors?
Corona, because the non-smooth conductor produces an uneven electric field, around the uneven electric field, near the electrode with a small radius of curvature, when the voltage rises to a certain degree, due to air ionization will occur discharge, the formation of corona. From the conditions o...Read More -
Cycle and continuous operation of the motor which is more prone to heat?
Different working conditions on the 3 phase motor requirements are not the same, simply from the work system, some working conditions need the motor to work continuously, and some motors can only be carried out in the alternating state of operation and shutdown, and different working conditions o...Read More -
Rotor problems in permanent magnet motor applications
Different 3 Phase Induction Motor products have different advantages and applicability. Due to different working conditions, the requirements for motor parts are also different. For example, for heavy-duty working conditions, there are special requirements for motor bearings and shafts, and for d...Read More
