What's special about the Pancake Mulit-Rotor BLDC?
1.the core technology --- electromagnetic array technology based segmentation of
high power density and high efficiency permanent magnet motor or generator controller
system composed . The system design utilizes materials science, computer-aided
design science, cybernetics and electromagnetic measuring physics.
2. the efficiency can reach 94 ~ 98% --- in patented technology - segmented
electromagnetic coil array technology unique molding technology , reducing the stator
copper loss . Abolition of the traditional motor core, it reduces lot of iron loss. And
eliminating the magnetic pull of the stator, the rotor between the bearing load is reduced,
thus reducing the consumption of electrical machinery ( especially for high-power
motors)
3. high power density can be achieved using a high energy product ---rare earth
permanent magnetic material , as compared with conventional motors , since the
design of the axial gap motor , the magnetic flux in the gap in the radial gas double gap
conventional motor design, but also does not eliminate the use of silicon steel magnetic
core saturation effect due to the cogging brings . Resulting in the same power level , the
volume of the motor is smaller than an ordinary motor , light weight.
4. the maximum torque multiplier can reach 10 times than traditional--- coreless
stator design , eliminating the ferromagnetic saturation effect . Thus, the maximum
torque curve of the motor in the operating range is linear. So the motor in the event of
sudden large load , better able to cope effectively adapt to the harsh operating
environment.
5. running very smoothly ---no core , there is making full-seamless inherent traditional
motor cogging , and the application of the motor controller controls EMF and current
waveform matching technique , so when the motor is in operation from the fundamental
on reaching the torque ripple silent except for the sound effects and bearing close to
zero .
6. The temperature is not high ---small size and light weight. Arguably harder than
conventional motor temperature to ensure its targets. But because of the high efficiency
of the motor , so the heat generated inside is comparatively small, and the application
of advanced computer-aided design software to optimize heat dissipation through the
motor and the internal geometry of the heat which can be issued when the motor high
torque and high current, smoothly discharged to the outside of the motor.
Main Pancake Brushless motor items feature &
specification:
With Pancake BLDC, we have made 4 series different types so far. In the
latest version, we make upgrade magnet material to N35EH NeFed level,
also drills more holes on the middle of stator holder for save more weight to
the complete motor mechanical.

Market Application Example:
Drug manufacturing and plant accidents can cause hazardous situations for civilians.
To detect drug labs, cultivation sites or elevated levels of toxins at plants, the police use
two different types of sensors. Heat sensors display the degree of heat in a location
whereas gas sniffers measure the level of toxins in the air.
Fire fighting is one of the most dangerous occupations in the world. While most people
move away from dangerous scenes, fire fighters are expected to enter hazardous
environments to evacuate distressed people or animals. During a fire fighting operation
rescue workers may face heat, flames and a toxic environment caused by combusting
materials.
High voltage lines are electrical lines that distribute power at high voltages. The
maintenance of these lines is a risky job, which requires careful attention and caution.
Power line maintenance involves examining the pylons, inspecting their insulators and
detecting thermo graphic problems.
Infrastructures are the veins of our society. Key infrastructures include technical
structures such as roads, bridges, waterways, airports and railroads. The maintenance
of these structures is costly, yet indispensable for the proper functioning of modern
economies.
Mapping refers to the graphic representation of information based on spatial
relationships.
Mapping is commonly practiced to portray scaled geographical features like water,
forests and roads. Mapping is an ongoing process as changing climate conditions and
structural developments make it necessary to perform mapping regularly.
