Servo Motors

The rotor of rotary AC synchronous servo motor is made of permanent magnet material, which directly generates the excitation magnetic field. There is no process of establishing the motor magnetic field with excitation current, so the electromagnetic response is fast. Moreover, due to the high energy density of rare earth permanent magnet materials, this kind of motor has high power density, which provides the possibility for further designing servo motors with various characteristics. The use of rare earth permanent magnet materials makes it possible for permanent magnet motors to be the first choice for servo motors. Because rare earth permanent magnet materials are still the most expensive part of servo motor materials. The difference of materials used by different manufacturers divides the product quality into different levels. AOMAG provides customers with good permanent magnet materials, which can not demagnetize at the working temperature above 150℃; However, some manufacturers provide poor permanent magnet materials, and demagnetization may occur when the motor working temperature is less than 120℃. Therefore, the permanent magnet material directly determines the different characteristics of servo motor.

magnets for servo motors

Our magnet servo motors by adding trace elements, using a special aging process, under the premise of ensuring the excellent performance of the magnet, the magnet microstructure parameters sensitive, more stable structure, to meet different use of the environment, to ensure the working status of the magnet stable and normal.

The most widely used magnetic materials in servo motors are sintered NdFeB materials and SmCo materials. Sintered neodymium magnet has great magnetic field strength, which can bring great torque to rotor and stator. Among the sintered NdFeB grades, H, SH, EH and UH series are widely used, because they can withstand the working temperature as high as 120-200 degrees without losing their magnetism. Customized servo motor magnets and high-performance motor tile magnets, AOMAG is your good choice!
