Pellet stove and boiler auger motor

     There are many core components in a pellet stove, including the burn pot, heat exchanger and the feed auger and auger motor. When consumers are choosing a pellet stove, the auger and auger motor are a very over looked components. However the power of the auger motor and drive system impact directly on how well the pellet stove.can deal with different types and batches of pellet fuel. The main issue that related to pellet stove auger motor requirements is the length and density of pellet fuel. Pellet fuel is produced at various different lengths depending on the knife setting in the manufactures pellet mill. Therefore some pellets are longer than others. Depending on the design of the pellet feed system and power of the auger motor, a pellet maybe required to be broken to fit through the auger feed tube. However in some pellet stoves this can cause serious issues, and potentially damage the auger, auger drive or auger motor.
    In order to solve this problem,One china company(www.jantmotor.com) develop a high torque motor,this motor not use shaded pole gear motor any more,but adopt a gearbox with synchronous motor.
    High torque,no noise,long life cheaper,all make more and motor company adopt this motor to improve his stove.
    we trust,This motor will change all the pellet feeder design at last.

A no noise pellet stove auger motor adopt by more and more pellet stove company

    For most of pellet stove,almost all the company adopt shade pole gear motor for pellet feeder  motor.

    But there is new design for auger motor now,one of chinese company(www.jantmotor.com) want use a synchronous gear motor to improve,hope to  replace the shaded pole gear motor,after 2 years study,this new motor is adopt by more and more stove company.

   This now motor no noise,higher torque,lower cost,long life.

   This is why more and more  grill smoker company and pellet stove company adopt this new design.

   

Pellet Fireplace motors

Fireplace can bring people a lot of joy, a lot of warmth. You can imagine that a person or a group of friends, sitting next to the fireplace, happy to talk, to share each other's stories, each other's mood, this is so wonderful.

   With the improvement of environmental awareness,more and more people adopt pellet fireplace.

   There are 3 shaded pole gear motor in pellet stove motor,there is key part in the pellet fireplace.

   One is shaded pole gear motor,one shaded pole motor with a gearbox,the motor always used YJ61-25 and Yj61-30,the other is exhaust fan motor,one shaded pole motor with big metal fan blade,the other is shaded pole motor with Axial flow motor.

  If your fireplace can not work,you can check control board and this 3 motors first.

Shaded pole motor structure

like most motor, shaded pole motor also includes a circuit, magnetic and structural parts of three parts, corresponding to the basic components of the stator and the rotor core, winding, brackets and bearings.

1) The motor rotor core for constituting a magnetic circuit, wherein the alternating magnetic flux to pass.

In order to reduce iron loss, are generally mutually insulated with silicon after punching. Ningbo Jant electrical appliance co Ltd  is commonly used 50W1300, 50W800.

2) the winding enameled wire wound on bobbins concentrated winding as the main winding copper wire and welded into a short ring as a secondary winding.

 There are several rotor, in which they talk about the most commonly used cage rotor, it is washed with alveolar rotor plate after stacked and pressed into the shaft after each rotor slot aluminum or cast into made of aluminum, cast into the rotor slot and the end of the aluminum conductor inside the die to form a short-circuit cage winding. Since the resistivity of aluminum conductor for motor performance has a great impact, therefore, requires careful selection grades upon request.

3)  NingboJant electrical appliance co Ltd bracket ge generally used zinc alloy, aluminum and other non-magnetic material, such as cold-rolled steel is also useful magnetic materials such as YJ58 series metal stents, YJ80 series of metal stents. It should be emphasized that the design of the motor bracket selection must be considered when the magnetic flux leakage problems.

4) The motor has bearing, sleeve bearing and ball bearings. With oil-bearing structure is simple, low cost, low noise and energy self-lubricating, etc., are widely used in household electrical appliances with motors. Bearing in the selection according to the operating conditions to determine the appropriate form, but also strict attention to the bearing chamber machining accuracy and assembly processes.

Shaded pole motor specification

1) Voltage (V) means the motor in normal operation, the stator windings to be connected to the supply voltage. different countries and regions use a lot of different voltage, so the motor voltage specifications are also many, such as: 120V, 230V, 220V, 240V, 100V, etc., is also useful in industrial applications, 12V, 24V, 36V, 45V and so on. Supply voltage tolerance of not more than ± 5%.

2) Frequency (Hz) is the frequency of the AC power, China's power grid frequency is defined as 50 Hz, some country use 60 Hz. Frequency allows the deviation does not exceed ± 1%.

3) Power (W) means the motor is running at rated mechanical shaft output power.

Our company's (Ningbo Jant Electrical Appliance c Ltd.,)motor nameplate rated power generally refers to the maximum input power.

4) Speed ​​(RPM) indicates the motor at the rated voltage, frequency and output power to run the rotation speed. Typically, the motor speed is the speed of the motor shaft(no load), for some specialty products is often expressed through the output gear of the actual rotational speed of the shaft(on load), shaded pole motor speed is lower than the power supply frequency and Electric poles synchronous speed determined.

5) Current (A) refers to the motor is running at rated conditions stator windings of the input current can be used to check whether the motor is overloaded or defective.

6) Efficiency (η) means the motor is running at rated output power and input power ratio. Generally in the motor to reach thermal steady state, with a dynamometer directly measured the output torque and rated speed records to calculate the output power, while the motor power input is read directly from the test instrument.

7) Insulation class indicates the motor winding insulation level for determining the allowable temperature rise of the motor, commonly used insulation levels are A, E, B, F, and H five, corresponding to the maximum operating temperature of 105 ℃, 120 ℃, 130 ℃, 155 ℃ and 180 ℃.

8) Some other indicators have been specially designed or special use of the motor, but also marked on the nameplate on the technical indicators, such as work methods (continuous, short-term, intermittent cycle operation), the thermal protection in the form (impedance protection, disposable thermal Insurance protection, etc.), power factor, starting current and torque overload factor and so on

How many kinds for YJ58 series shaded pole motors
