High efficiency and energy saving of three-phase asynchronous motors have always been the continuous research and development guidelines of major high-efficiency motor manufacturers, and high-efficiency motors are directly related to national energy-...
The motor is one of the most common machines. It is a device that converts electromagnetic energy into machine energy. It is widely used in various scales. In the process of energy conversion of high-power motors, some simple and huge factors may cau...
Shaft current occurs when a variable frequency motor is running, and it is common in high-power variable-frequency motors. Because when a high-power variable-frequency motor is running, when the stator core of the motor is unbalanced in the reluctanc...
For high-power motors that require forward and reverse rotation, if the full-speed motor is braked in the reverse direction and rotates in the reverse direction, the energy consumed by the rotor at this time is much larger than the energy consumed du...
There are many three-phase asynchronous motor manufacturers, and the quality and value of each are not communicated. Although my country has already drawn up the standards for motor production design skills, many companies have conducted adjustments ...
Compared with ordinary motors, there is not much difference in appearance between frequency conversion motors and ordinary motors, but there is a big difference between the two in terms of function and utilization. The frequency conversion motor is p...
The noise source of the motor can be divided into electromagnetic noise, machine noise and ventilation noise according to the cause of occurrence. Electromagnetic noise The magnetic field in the air gap of the motor is contaminated with each other an...
The vibration of the motor will shorten the winding insulation and bearing life, affect the normal lubrication of the sliding bearing, and the vibration force will promote the expansion of the insulation gap, which will cause the intrusion of externa...
