Permanent magnet synchronous motor axial flow pump is a new advanced application of permanent magnet synchronous motor in the field of pump. It has the characteristics of high efficiency, lightweight, a small volume (only 1 / 4 of the weight of a traditional axial flow pump), large flow and convenient movement. Moreover, stepless speed regulation, head and flow can be adjusted by adjusting speed.
At the same time, another characteristic of permanent magnet synchronous motor is that the speed does not change with the grid voltage. When the voltage changes, especially when the voltage is low, it can still keep the head flow unchanged, which is unavailable in the traditional axial flow pump of the asynchronous motor.
