Magnet assembly for Linear Motor

Flat magnet linear motor
Linear motor is often described simply as a rotary motor that has been rolled out flat and the principles of operation are the same
Forcer (rotor) is made up of coils of wires encapsulated in epoxy and the track is constructed by placing Magnets (usually high-powerful Neodymium Magnets) on steel

Permanent Magnet synchronous linear motion has excellent performance and it is widely used in the precision transmission system
According to the shape of the motor, it can be divided into U-type linear motor, flat-type linear motor and axial linear motor
We mainly produce U-type linear motor and flat plate linear motor

1. Materials
Magnet: Neodymium Magnet
Hardware part: 20# steel, martensitic stainless steel
2. Applications
U-channel and flat brushless linear servomotors have proven ideal for robots, actuators, tables/stages, fiber-optics/photonics alignment and positioning, assembly, machine tools, semiconductor equipment, electronic manufacturing, vision systems and in many other industrial automation applications

Why choose Linear Motor?

1. Dynamic performance
Linear motion applications have a wide range of dynamic performance requirements
Depending on the specifics of a system's duty cycle, the peak force and maximum speed will drive the selection of a motor:
An application with a light payload that requires very high-speed and acceleration will typically utilize an ironless linear motor (that has a very light moving part containing no iron)
As they have no attraction force, ironless motors are preferred with air bearings, when the speed stability has to be below 0.1%

2. Wide force-speed range
Direct drive linear motion deliver high-force over a wide range of speeds, from a stalled or low-speed condition to high velocities
Linear motion can achieve very high velocities (up to 15 m/s) with a trade-off in force for iron-core motors, as technology becomes limited by eddy current losses
Linear motors achieve very smooth velocity regulation with low ripple
Performance of a linear motor over its velocity range can be seen in the force-speed curve present in the corresponding datasheet

3. Easy integration
Magnet linear motion is available in a wide range of sizes and can be easily adapted to most applications

4. Reduced cost of ownership
Direct coupling of the payload to the motor's moving part eliminates the need for mechanical transmission elements such as lead-screws, timing belts, rack and pinion and worm gear drives
Unlike brushed motors, there is no contact between the moving parts in a direct drive system

Therefore there is no mechanical wear resulting in excellent reliability and long lifetime, fewer mechanic
