Zhejiang Baolun central air conditioning fan coil electric two-way valve hysteresis moto

Zhejiang Baolun valve specializes in the production of hysteresis motors for electric two-way valves and electric ball valves of central air conditioning terminal systems
Product Name: electric two-way valve hysteresis motor, permanent magnet motor, fan coil end system electric valve motor, electric ball valve motor, permanent magnet synchronous motor
Product introduction: hysteresis motor is a small power synchronous motor that uses hysteresis torque to start and operate

Product meaning: a small power synchronous motor that uses hysteresis torque to start and operate

Product composition: its rotor is made of permanent magnet materials with remanence and coercivity comparison da
Only two magnetic molecules 1 and 2 are drawn on the rotor
They are all on the central magnetic line of force
Their polarities N and s are determined by the stator magnetic poles
Since the axis of the magnetic molecule is consistent with the axis of the stator magnetic field, there is no tangential force and torque
If the stator magnetic field rotates by an angle from the position in figure a (Figure b), the rotor unit magnet cannot rotate by the same angle immediately due to the Da internal friction between the magnetic molecules of the permanent magnet material, so the hysteresis phenomenon occurs, and there is an included angle between the axes of the two θ, The magnetic lines of force are twisted, resulting in tangential force and torque
This kind of torque caused by hysteresis is called hysteresis torque
If the magnetic field rotates continuously, the rotor will be driven to rotate together
In the starting process of hysteresis motor, there are not only hysteresis torque, but also asynchronous torque generated by rotor eddy current Chan, so it is easier to start and pull in synchronization
The stator structure of hysteresis motor is the same as that of asynchronous motor
It can be three-phase or single-phase
If it is single-phase, separate phase starting measures shall also be adopted (see single-phase asynchronous motor)
The hysteresis ring made of iron cobalt vanadium or iron cobalt molybdenum alloy is usually sleeved on the magnetic or non-magnetic sleeve of the rotor
The sleeve is mounted on the shaft
Magnetic sleeve or non-magnetic sleeve can be used, and their magnetic line diameters are different

Product structure: the hysteresis motor has simple structure, reliable operation, relatively Da starting torque and low noise, and can drive the load with relatively Da inertia to be smoothly pulled into synchronous operation
Its disadvantage is that the efficiency is not high, and the volume and weight of the motor are higher than other types of synchronous motor Da, and the price is more expensive
It is often used in clock mechanism, recorder, television equipment, recording instrument, gyroscope and other synchronous driving devices of automation systems

The electric two-way regulating valve series can regulate the flow of steam or cold and hot water, and is widely used in the fluid control of central air conditioning, heating, water treatment, industrial processing industries and other systems

1、 Product features: 1
It is used to control the opening or closing of cold water or hot water air conditioning system pipes to achieve the purpose of controlling room temperature
2
The driver is driven by a single-phase hysteresis synchronous motor, the tan spring of the valve is reset, and the valve is in a normally closed state when it is not working
When it needs to work, the thermostat provides an opening signal to make the electric two-way valve act by connecting the AC power supply
3
Open the valve, and the chilled water or hot water will enter the fan coil to provide air conditioning or heating for the room
When the room temperature reaches the set value of the temperature controller, the temperature controller will power off the electric two-way valve, reset the tan spring to close the valve, so as to cut off the water flow into the fan coil
By closing and opening the valve, the room temperature will always be kept within the temperature range set by the temperature controller
4
The driver of the electric two-way valve is connected with the valve by thread, and the driver can be installed after the valve is installed
Field assembly, flexible and convenient wiring
The plane design of the driver can be installed close to the wall, with small space occupation, reliable and durable products, low working noise, and can work reliably in the high temperature and high humidity environment that often occurs in the concealed fan coil unit
