Mainly used in fans, pumps, compressors, machine tools, light industry and mining machinery, agricultural pr...Read More -
60MW super power high speed synchronous motor and drive control system
The TZYW-50000kW 4P/10kV positive pressure ventilation explosion-proof synchronous motor and RMVC-60000kVA/10kV ultra-large capacity high voltage inverter developed by Wolong electric Drive won the “Global Chemical Equipment’s first set of Cooperative Research and Development Contribu...Read More -
The Mysterious Construction, Important Role of High Voltage
Electricity is an indispensable part of our daily life, and high voltage transformer is one of the key equipment for power transmission and distribution. However, most people may not understand the high-voltage transformer, this article will take you to understand the structure and role of the hi...Read More -
Explosion-proof motors need to do before the use of preparatory work
Explosion-proof motors need to do a series of preparatory work before use, in order to ensure that explosion-proof motors in operation can maintain the normal state, this step is very critical, then we need to do those jobs before use? I. Preparation 1. Collect materials according to the assembly...Read More -
The magnetic steel of the permanent magnet motor is on the stator or the rotor？
Most of the motors are internal rotors, that is, the motor rotor is located inside the stator and outputs mechanical energy through the rotating shaft. The external rotor motor is on the contrary, the initial wire winding is placed on the iron core fixed together with the shaft, the motor is in a...Read More -
Motor bearing and grease selection
The motor is widely used, due to the power size, installation type, protection grade, load type and connection method is different, the selection of bearings is also very different, only the correct selection of bearing type, so that it can adapt to the operating requirements of the equipment, in...Read More -
Considerations for structural design of explosion-proof three-phase asynchronous motors
Explosion-proof motors, as the main power equipment, are usually used to drive pumps, fans, compressors and other transmission machinery. Explosion-proof motor is the most basic type of explosion-proof motor, because of its shell non-sealed structure characteristics, the main flammable gas gas in...Read More -
Why should we choose deep groove rotor for squirrel cage asynchronous motor?
With the popularization of variable frequency power supply, the starting problem of motors has become easy to solve, but for ordinary power supplies, the starting of squirrel cage rotor asynchronous motors has always been a problem. From the analysis of the starting and running performance of as...Read More -
The formation and harm of axial force in motor operation
Three-phase AC synchronous motor or asynchronous motor (hereinafter referred to as three-phase AC motor), when the stator winding is connected to the power supply, that is, a rotating magnetic field is generated, so that, for asynchronous motor, the rotor is induced current due to electromagnetic...Read More -
Control motors 5 major classifications
Control motors are mainly used for precise speed and position control and as “actuators” in control systems. They can be categorized into servo motors, stepper motors, torque motors, switched reluctance motors, brushless DC motors, and so on. 1. Servomotors Servo motors...Read More -
Large motor shaft voltage analysis and solutions
Four sets of bearings were replaced consecutively at the shaft extension end of a motor, which was eventually found to be due to shaft voltage. Shaft voltage is a frequent problem in the operation and testing of high-voltage and low-voltage high-power motors. In order to ensure the normal operati...Read More -
When selecting an inverter, is it necessary to consider the slot characteristics of the motor rotor?
For continuous changes in speed requirements for the conditions, will use a frequency converter to drag the motor, that is, through the motor power supply frequency changes, to achieve stepless adjustment of motor speed. In the original tweet we have talked about, through the frequency converter ...Read More
