Detailed Description
Direct Drive Motor System
The new self-developed external rotor motor with large torque and permanent magnet synchronization replaces the traditional motor+gearbox reducer, achieving a high degree of integration and improving reliability and transmission efficiency.Aluminium alloy material is adopted in many parts to realize the lightweight design.
Fan Blade
It is made of aluminium and magnesium alloy extruded and stretched, and has the advantages of high strength, good toughness,
lightweight, long life and safe operation. The fan blade surface is treated with T5+ bright surface oxidation treatment, which
enhances the corrosion and oxidation resistance of the fan blade and can cope with special environmental operations.Energy saving tail.

Torque
|
Small diameter，small moment of inertia，high KV value，low torque
|

|
Number of poles
|
Small rotor surface area
, can design a few poles, generally 16 poles
|
Large rotor surface area
, can design more poles, generally more than 52 poles
|
|
|
||
|
Construction of winding
|
Fewer winding poles,higher temperature rise
|
large winding poles,low temperature rise
|
|
|
||
|
Heat dissipation
|
Inner rotor motor operates at low frequency,the winding has high calorific value
|
The outer rotor motor runs at regular frequency and the winding heat is low
|
|
|
||
|
Demagnetization
|
Magnetic steel is embedded, in the winding heating source, poor heat dissipation, easy to lead to slow demagnetization.
|
The magnetic steel is embedded in the inner ring of the casing, with a large heat dissipation area, and in the outermost ring of
the casing, the heat dissipation effect is the best, the temperature resistance of the magnetic steel and the actual temperature
difference of more than 60 degrees, there is enough margin, so as to ensure the absolute life of the magnetic steel.
|
|
|
||
|
Magnetic steel fixation
mode
|
embedded
|
With special magnetic steel track card slot, Mosaic fixed, add special glue paste on the outer wall of the housing, so as to
ensure that the magnetic steel firm and never fall off
|
|

|
Difficulty of winding maintenance
|
Notch inward,professional tools for maintanence，high difficulty
|
Notch outward,
No need for professional tools,
Low repair difficulty

Stability
|
The motor shaft end need to be installed with the shaft skeeve and impeller disc,then mount the fan blades.High center of gravity,
impeller overall flat
Poor balance (maximum force from blade tail)
|
The blade support is mounted directly on the housing.when the motor housing is running ,the motor movement is static Higher
stability, larger contact surface, low center of gravity, the overall balance of the machine is the best (maximum force from the
blade tail)
|
|
|
||
|
Ceiling fan Force
|
Using a smaller shaft, the entire blade group is completely fixed by a bolt or clamp
|
Adopt large motor shaft, motor shaft is made of high strength and toughness steel, can withstand great gravity and torsion force)
|
|
|
||
|
safety protection
|
The wire rope only has traction motor part, and the fan blade part is a separate part, so the whole fan blade group cannot be
protected safely
|
Wire rope pulls the whole ceiling fan, and the whole machine is protected safely (Our fan also has a third shaft protection
against breaking
|
|
|
||
|
Output
|
The inner rotor needs good heat dissipation, such as adding a fan)
|
Under the same volume, the outer rotor has a larger torque output and power output so that it can drive a larger air volume
|
|
|
||
|
Heat dissipation of motor by ceiling fan
|
The ceiling fan speed is low and the inner ring air volume is less, it does not help the motor heat dissipation much.
|
The ceiling fan motor is natural heat dissipation, so the bigger the motor surface is, the better the heat dissipation is.
