A 1. Why use a frameless motor?

A 1.How thin can the axial thickness of an axial flux motor be? What are the maximum and minimum outer diameters?

Wheatstone provides customers with the best solutions within the applicable range.

2.How do axial flux motors dissipate heat, and are they prone to overheating?
Axial flux motors do face significant thermal management challenges, primarily due to their compact, high-power-density design. However, they are not inherently prone to overheating; rather, their ability to dissipate heat depends entirely on the cooling system integrated into the design. A wide range of innovative cooling strategies—from advanced liquid systems to passive heat pipes—are employed to effectively manage heat and ensure reliable operation

3.What is the total weight of the Axial Flux Motors? Does it meet the weight reduction requirements?
Axial flux motors are celebrated for their exceptional power-to-weight ratios, and the data strongly confirms that they significantly outperform conventional motors in weight reduction. The total weight varies greatly by application, but the technology consistently demonstrates a massive weight advantage.

Common applications include:

• Semiconductor wafer handling and vacuum tooling.

• Electron microscopes, mass spectrometers, and surface analysis instruments. 

• Spacecraft mechanisms and satellite positioning hardware (e.g., antennas, solar arrays). 

• Any clean or UHV environment where outgassing must be minimized.

A A vacuum stepper motor is a type of stepper motor engineered to operate inside low-pressure environments (vacuum chambers) without contaminating the vacuum or degrading performance. They use low-outgassing materials, special lubricants, and construction techniques to work reliably in vacuum levels down to high vacuum or ultra-high vacuum

Underwater motors are commonly used in ROVs (Remotely Operated Vehicles), AUVs, submersible pumps, underwater robots, marine propulsion systems, offshore equipment, and environmental monitoring devices.

A

Most underwater motors meet high ingress protection standards such as IP68 or higher. For deep-sea applications, motors may also be designed to withstand high hydrostatic pressure beyond standard IP ratings.

A Underwater motors can be designed for shallow water, deep water, or extreme-depth applications. The maximum operating depth depends on sealing technology, housing strength, and pressure rating, and can be customized for specific depth requirements.

A

Unlike standard motors, underwater motors are designed with enhanced sealing, special insulation, and anti-corrosion materials. They can withstand water pressure, prevent leakage, and operate continuously underwater without electrical or mechanical failure.

Vacuum servo motors are widely used in semiconductor manufacturing, vacuum coating systems, aerospace testing, scientific instruments, particle accelerators, and space simulation equipment.

A Vacuum servo motors can be designed for different vacuum ranges, including low vacuum, high vacuum, and ultra-high vacuum . The achievable vacuum level depends on motor materials, lubrication method, and thermal design

A

No. Standard servo motors are not suitable for vacuum environments because their lubricants, insulation materials, and coatings may outgas, overheat, or degrade. Vacuum servo motors are specifically engineered to address these issues.
