Like our polyurethane rubber coated mounting magnet ?

Most magnets have a strong direct pull force but they can be made to slide along a surface with about 20% of the direct pull force when used on steel. Rubber coated Mounting Magnet has a strong direct pull force but the increased friction of the polyurethane means that it takes around twice the direct pull force to get the magnet to slide.It can provide immense resistance to shear forces when mounted on a smooth metal surface, as typically found on motor vehicle body parts.

Typical uses include car roof signs, antenna clamp systems, vehicle tracking units, temporary signage, attaching to boards and pictures for clamping to metal partitions, etc.

Please be aware note that magnets will not attract to panels are made of non-magnetic materials such as aluminium or carbon fibre; the majority of car panels have ferromagnetic mild steel content which magnets will attract strongly onto.

Axial Flux Motor Magnet

Axial Flux Motor Magnet

What is axial flux motor?
The motor can be divided into axial flux type and radial flux type according to the direction of magnetic field. The world’s first motor was invented by Michael Faraday on 1821. Actually, Faraday motor is belong to axial flux motor, but the further development of axial flux motor was limited by the material and technological level at that time. Conversely, the radial flux motor which invented by Davenport on 1834 taking the lead in development, and became known as the simple motor.

first motor

The air gap of axial flux motor is a planar, and its air gap magnetic field distribution along the axial direction, that is, the air gap magnetic field is perpendicular to the air gap plane. The current development trend of the motor is high speed, low weight and high efficiency, and the axial flux motor is regarded again under this circumstance.

Radial flux motor and axial flux motor

Advantages of axial flux motor
Compact structure, especially short axial sizes.
Small volume
Low weight.
High torque density.
High power density.
Small end-winding.
Excellent cooling performance.

Application of axial flux motor

Application of axial flux motor
Based on above advantages, axial flux motor is perfect for high torque density and space compact applications. Most people believe that the high power density only depends on high speed, and overlook the influence of torque density. The mere pursuit of high speed will lead the short service time and noise. In fact, the core of the high speed motor is the enhancement of torque density, and axial flux motor is a typical solution among them.

About Axial flux motor magnet
MPCO Team has been collected a lot of useful experience on axial flux motor magnet during these years. Here below two simple solutions for axial flux motor magnet:

Axial flux motor magnet with skewed fan shape

a. Axial flux motor magnet with skewed fan shape

For slotted motor, the cogging torque cannot be avoided due to the interaction between the permanent magnet and the stator tooth, hence lead to torque ripple, vibration and noise. The cogging torque of axial flux motor will be suppressed after changing the traditional fan shape axial flux motor magnet into skewed fan shape.

Laminated type axial flux motor magnet

b. Laminated type axial flux motor magnet

Axial flux motor is also suffering from eddy current losses, and its work efficiency will be also affected by the high temperature demagnetization. Magnet segmentation technique is an advisable choice to decrease the eddy current losses of axial flux motor magnet. It should be noted that the effects of horizontal segmentation will be much better than vertical segmentation’s.
