Beijing, May 25, 2005 — Danaher Motion, Inc., the world's leading manufacturer of motion control products, today announced the introduction of the PORTESCAP ultra-magnet (Pc Magnet) stepper motor with rare earth permanent magnet materials (SmCo and NeFe). The emergence of this innovative motor not only greatly improved the performance of the stepper motor, but also has a milestone in the development of the entire stepper motor field.
The new PORTESCAP ultra-thin magnet stepper motor uses rare earth permanent magnet material to ensure the motor's high positioning accuracy in terms of fast motion increment performance such as acceleration and power. The rare earth permanent magnet of the motor can force the magnetic flux beam to pass through the air gap (Airgap) densely, and prevent the magnetic flux line near the air gap from diffusing and scattering, thereby maintaining a certain moment of inertia, and achieving precise control and positioning operations such as microstepping and closed loop. When linearly expanding overcurrent, the motor can generate additional torque during the acceleration phase, further improving positioning accuracy. In addition, this stepper motor also has an ideal torque-displacement sinusoid to avoid harmonic distortion.
It is reported that the rare earth permanent magnet ultra-thin magnet stepper motor can be widely used in many fields such as medical, aerospace, electronic processing and semiconductor production. Its superior product performance helps users focus more on the system without having to be constrained by the problem of stepper motor matching. This will help users greatly increase productivity, reduce costs, and simplify system management.
At present, China is developing rapidly in the world manufacturing center. While domestic OEMs continue to expand their production scale, they are also eager to improve the technical content of their products. The newly launched PORTESCAP ultra-thin magnet stepper motor can meet the needs of domestic customers, further helping domestic manufacturers to increase product added value and enhance their comprehensive competitiveness.
As the world's leading manufacturer of motion control products, Danaher Motion has always been closely monitoring the actual needs of customers in the global industrial control field, and is committed to providing customers with the most competitive products. This time, Danaher Motion will launch this product in China, which will further strengthen Danaher Motion's leading position in motion control and expand and enhance the company's service scope and capabilities to Chinese manufacturers.
About stepper motor technology Stepper motor technology can be divided into two categories: permanent magnet stepper motor and permanent magnetless stepper motor. The permanent magnet stepper motor technology has traditionally been divided into three categories, including inductive stepper motors (VR), permanent magnet stepper motors (PM), and hybrid stepper motors (HB). Although both VR stepper motors and PM stepper motors use magnets instead of windings. But these two different technologies have their own advantages. The VR motor has a small step angle, and the PM motor has better performance due to the magnet in the air gap of the motor. Hybrid stepper motors retain the advantages of VR stepper motors and PM stepper motors by having permanent magnets and cogging that change the actual air gap when the rotor rotates.
