The problem of speed regulating motor and general motors
Frequency conversion for speed adjustment, speed regulating motor is frequency conversion motor, which is integration with frequency converter, ordinary motor optimization design, of course, but with general motor and frequency converter not too big difference, no single common motor speed control function. By tuning the pump if the requirements for precision of speed is not very high (not less than 0.5%) is no problem, just ordinary motor and frequency converter in the installation and operation, as well as reading is more troublesome, and must choose the appropriate power inverter (is greater than the power of the motor). The life of the ordinary motor and frequency converter generally does not reduce back, of course is related to the frequency and the number
Of course must be better than the general motor. On the electromagnetic, due to the variable frequency power supply with accompanying wave current, frequency conversion motor by the special design, can reduce the resulting electromagnetic loss. In addition, the speed control system for motor has higher sensitivity and should minimize its moment of inertia. Speed regulating motor in these areas have special design. Of course also can be used as ordinary motor speed regulating motor, but it won't pay!
With frequency converter, of course, will not shorten the life of the motor, ordinary motor frequency converter will be used to take, no problem at all, music fountain is with motor with frequency converter
