If you want to distinguish Deep Well Self-priming JET Pumps motors from ordinary motors, you must understand their basic principles, and then it will be easy to understand. The frequency conversion motor is first of all a frequency conversion motor: the motor adopts the AC speed regulation mode of ‘special frequency conversion induction motor + frequency converter’, which greatly improves the degree of automation and production efficiency of the machinery and greatly improves the miniaturization and comfort of the equipment. It is currently replacing traditional machinery.
Speed regulation and DC speed regulation scheme. The variable frequency motor can be adjusted at any speed within its speed range, and the motor will not be damaged. Generally, most domestic ordinary motors can only run under the conditions of AC380V/50HZ. Ordinary motors can be used in frequency reduction or frequency increase, but the range It should not be too large, otherwise the motor will heat up or even burn out. Ordinary motor
The cooling fan in the ordinary fan and the fan core use the same line, but the two in the frequency conversion fan are separate. Therefore, when the frequency conversion of ordinary fans is too low, they may burn out due to overheating. Since frequency conversion motors have to withstand high-frequency magnetic fields, their insulation levels are higher than ordinary motors. In principle, ordinary motors cannot be driven by inverters.
However, in practice, ordinary motors are used in many occasions where speed adjustment is required to save money. It replaces the frequency conversion motor, but the speed regulation accuracy of ordinary motors is not high. This is often done in the energy-saving transformation of fans and pumps. When replacing the variable frequency motor with an ordinary motor, the frequency of the frequency converter is as low as possible to reduce the insulation damage to the motor due to high frequency. The characteristics of variable frequency motors:
