Permanent magnet shaker PM series

Standard shaker tests can be driven at different frequencies and amplitudes. For these tests, the specimen can be attached directly to the shaker armature and the vibrating surface can be increased by using a head expander to suit the specimen size. Vertical excitation can be converted to horizontal excitation by using a slip table. In some cases, instead of changing the direction of vibration, the part can be rotated and tested. Test duration and vibration levels are determined from test standards or real-time measurements. Dynalabs permanent magnet shakers are compact, lightweight and powerful general purpose shakers that can be used for modal and vibration testing. Despite their small size, they have a high DUT capacity. The DYN-PM-20 and PM-100 have an integrated amplifier and sine wave generator with a frequency range of 1Hz to 12,000Hz. Applications: • Vibration testing of micro parts, assemblies and electronics • Sensor calibration • Modal testing • Shock testing • Fatigue and resonance testing • Velocity transducer or high-speed actuator • Mechanical impedance measurement • Education and research Advantages: • Lightweight, durable, portable and easy to use • Adjustable trunnion base provides high degree of flexibility • Broad frequency range • Embedded power amplifier and signal generator for PM- 20 and PM-100
