Permanent magnet synchronous motors can provide users with more intelligent services by adding
temperature control devices on the basis of normal use. When the temperature is high during the day,
the permanent magnet synchronous motor runs at full load. At night, as the ambient temperature drops,
the return water temperature will also drop. At this time, the temperature sensor will feedback data to
the inverter of the permanent magnet synchronous motor. The inverter adjusts the output frequency and
changes the speed of the permanent magnet motor to make the return water temperature rise to the
temperature required by the customer to meet normal use requirements.Assuming that the wet bulb
temperature is 28ºC during the day and the wet bulb temperature is as low as 20ºC at night, the energy
saving effect of the permanent magnet synchronous motor running at full load during the day is about
20%, and the energy saving effect of the permanent magnet synchronous motor running at low load at
night is about 80%, and the average energy saving effect throughout the day reaches 50~60%Permanent magnet synchronous motors can provide users with more intelligent services by adding
