 Curved Magnetic Linear Motor
  Permanent magnet synchronous linear motor has excellent performance and it is widely used in 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 magnet linear motor, flat plate magnet linear motor and curved magnet linear motor.
 Synchronous linear motors are straightened versions of permanent magnet rotor motors.
 The curved magnet linear motor have a smart design that compensates for force losses in the curves due to commutation error, which occur due to straight coils on curved tracks. Standard motors can be used which have a low attraction force in respect to their continuous force exerting low wear on the bearings. They also have low cogging which gives in combination with a cogging compensation algorithm for the curved sections gives a very smooth moving.
While machines are often designed with strictly linear motions in mind closed tracks are interesting for many applications.       

   With the new curved magnetic linear motor assembly design from Faizeal many more versatile track configurations are possible. As The benefits of ironless magnetic linear motors are optimal for applications that require small masses to be moved with maximum precision at a high cycle speed, especially in areas like:

1. Semiconductor

2. Flat Panel Display

3. Inspection stages

4. Ultra precision stages

5. Medical / life science / lab automation

        6. Optics                                 
Why choose Linear Motor?
1. Dynamic performance
Linear motor 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 motors deliver high force over a wide range of speeds, from a stalled or low speed condition to high velocities. Linear motors can achieve very high velocities (up to 15 m/s) with a trade off in force for ironcore motors, as technology becomes limited by eddy current losses.
Linear motors achieve very smooth velocity regulation, with low ripple. The performance of a linear motor over its velocity range can be seen in the force-speed curve present in the correponding data sheet. 
3. Easy integration
Linear motors are 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 leadscrews, 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 mechanical parts minimize maintenance and reduce the system cost.
