What are the diagnostic methods for broken rotor bars in motors
06-12-2019
The fault diagnosis method of the broken rotor bar of the motor is as follows: An analysis method based on the residual voltage of the stator of the motor when it is out of power: The outstanding advantage of this method...
How to determine the power when the nameplate of the motor is lost
29-11-2019
When the motor nameplate comes off, there is no way to know the power of Taichuang Motor through the nameplate. At this time, you need to calculate it by measuring the resistance. If it is an ordinary standard motor, you...
What is the difference between the rated power of the motor and the actual power
23-11-2019
The difference between the rated power of the motor and the actual power is that the motor is in the best working condition under this data. The rated voltage is fixed with a tolerance of 10%. The actual power and actual...
How to choose a variety of motor models
15-11-2019
There are many different types of motors that can be purchased in different machining industries, but many manufacturing industries use geared motors. Whether the geared motors are mechanically matched or can achieve a h...
What is the relationship between the number of motor poles and the speed
09-11-2019
The pole number refers to the magnetic pole formed by the rotor after the rotor coil has passed the excitation current. Briefly speaking, each revolution of the rotor can induce several cycles of current divergence in on...
What is the reason for the large no-load loss of the motor
01-11-2019
Under normal circumstances, the ratio of no-load loss to rated power is calculated as a percentage, generally in the range of 3%-10%. For motors of the same specification, the fluctuation range of the no-load motor is 5%...
