ALXION TORQUe MOTORS

· Compact design. High torque, small dimensions to limit inertia .

· Lowest cogging torque, (less than 1% rated torque) thanks to specific winding concept. That induce high accuracy for positioning and accurate speed control .

· Very low dynamic error. (Tracking error)

· Very constant ripple torque (or harmonic torque)  which      valid constancy of rotation

· No magnet ungluing, which provide higher reliability.  

· No winding blast.

· Very high insulate protection up to 300.000 V

Achieving more together!!!
Allytech is your solution provider for drives in rotation

ALXION, as a  pioneer in Torque Motor Technology, thanks to  its long experience offers the most reliable and the most performing units. 

 

Thanks to economical and technical optimization provided by materials evolution and performing simulation tools, ALXION has designed and industrialized three ranges of brushless motors for Direct Drive : the FC and ST built-in ranges of motors " ready to use " and the STK range of frameless brushless motors.

 

Moreover, the STK frameless alternators experience a large growth in the field of wind turbines in direct driving.

The alternative to worm gear is direct drive, through a torque motor. ALXION torque motor (www.alxion.com), thanks to very profitable cogging factor, makes high speed very easy. The high dynamic of Alxion torque motor find advantages when application require frequent acceleration, or frequent change of rotation (cw/ccw). 

 

 

Due to its cutting edge design, limiting the mechanical parts, ALXION cinematic regulation and noise level are best-in-class. Applications are as diversified such as :

· Machine tool

· Printing machines,

· Plastic injection machines,  

· Textile industry,

· High tech production,


This technology become very familiar in wind turbine application,  where its act as an alternator.

Several configurations are available.

FC MOTORS :

Based on the idea that a specific range should be elaborated, the FC motors range with high torque for axis without reducer was born in the beginning of the 90'.

 

This project, supported by the National Agency for Enhancement of Research, led ALXION to develop a range of 7 permanent magnets brushless motors, specially designed for direct drive applications in various industrial environments. The motors exist in 230 Vac and 400V / 460 Vac windings.

brushless motors
for direct drive

STK MOTORS :

Designed to be integrated at the heart of servomechanisms with the aim to improve the performances of axis control.

Thus, the use of ALXION's Direct Drive Technology offers adequate solutions regarding the improvement of dynamic performances and accuracy and allows to address applications with demanding constraints on volumes and weights.

ST MOTORS :

To address the industrial new needs, ALXION creates this low inertia motors range.

 DIRECT DRIVE allowing acceleration up to 20.000 rad/s². 145 ,190 and 300ST ranges present an outstanding compacity with a continuous torque-to-weight up to 3.7 Nm/Kg and a peak torque-to-weight up to 18 Nm/Kg.
