Permanent Magnet Shakers-modal shaker

The JOEO Permanent Magnet Shakers is a compact, lightweight and powerful universal vibrator for modal and vibration testing. Despite their small size, they have a high DUT capacity, with integrated amplifiers and sine wave generators. For these tests, you can attach the sample directly to the vibrator armature and use a head expander to increase the vibrating surface to fit the sample size. A slide table can be used to convert the vertical excitation to the horizontal excitation. In some cases, it is possible to rotate and test components instead of changing the direction of vibration. Test duration and vibration levels are determined by test standards or real-time measurements.

• Compact design, portable and easy to use
• Small excitation test system is the use of permanent magnetic steel to form a static magnetic field, does not require additional excitation power supply, simplifies the requirements of power amplifier, small heat, no cooling device.
• The robust and lightweight mobile armature ensures adequate support for the test load without compromising performance.
• The sample can be attached directly to the vibrator armature and the vibrating surface can be increased to accommodate the sample size using a head expander
• A slide table can be used to convert the vertical excitation to the horizontal excitation. In some cases, it is possible to rotate and test components instead of changing the direction of vibration
