Permanent Magnet Shakers

Permanent magnet shakers create motion by a pair of magnets and coils pushing and pulling each other. In fact, the technology inside is not different from that in loudspeakers and they are also called voice coils.

Dynalabs shakers differ from all other similar shakers in that we build amplifiers into our shakers to make them very easy to use. The electronics built into the shakers can also generate sinus signals that allow simple tests to be performed. This allows test setups to be tested without the need for vibration controllers.

Dynalabs Permanent Magnet Shakers are the best solution for general purpose shakers that fulfill modal and vibration testing needs with their lightweight construction and incredible power. Don’t let their small size fool you as these shakers have an impressive DUT (Device Under Test) capacity.

The DYN-PM-20 and PM-100 models are each equipped with an integrated amplifier and a highly flexible sine wave signal generator. This outstanding feature allows you to smoothly adjust the frequency, covering an impressive range from 1 Hz to 12,000 Hz.

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

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
