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%...
Factors affecting motor loss
26-10-2019
Input voltage changes. Compared with the rated voltage of the motor, the input voltage will have different degrees of deviation during actual operation. When the operating voltage is slightly lower than the rated voltage...
Why is the power supply voltage high causing damage to the motor windings
19-10-2019
The power supply voltage is high, the excitation current is increased, and the motor will distribute heat. Excessive high voltage will insulate the motor and cause it to be broken down. When the power supply voltage is t...
How to check the insulation of the motor during use
12-10-2019
Inspection of insulation conditions. The insulating ability of insulating materials varies with the degree of drying, so it is very important to check the drying of the motor windings. The motor's working environment is ...
