Theory of Operation
DYN-PM-100 is an electro-magnetic actuator. Electro-magnetic actuators are
basically voice coils consisting of a permanent magnet and coil. The moving
element can be the coil or the magnet depending on the design requirements.
The moving element is usually suspended by an elastic membrane.
DYN-PM-100 has a moving coil (driving coil) whose current is controlled for
vibration generation. The stationary magnetic field is produced by a permanent
magnet.

Outline Drawing
The dimensional properties of DYN-PM-100 shakers are given below.
Operation and Installation
General
The general shaker connector configuration is given below.
External Signal Mode
Connect DC power source and drive signal to shaker power input and signal
input respectively. Start the external signal source. Adjust the Gain of the
amplifier by turning the Gain Knob clockwise.
Internal Signal Mode
The amplifier can generate sine signal from 1Hz to 15kHz with 1 Hz increments
that the user can adjust with the Sine Frequency Generator Switch. Connect DC
power source and drive signal to shaker power input. Pull the Gain Knob out.
Raise or lower the Sine Frequency Generator Switch to the desired Sine frequency. Adjust the Gain of the amplifier by turning the Gain Knob clockwise. The frequency of the generated sine signal will be visible on the LCD Screen.
Power Requirements
DYN-PM-100 has an integrated power amplifier which is powered by its power
adaptor. Please note the output voltage and current ratings of the adaptor in
a replacement adaptor is to be used.
Cooling
DYN-PM-100 does not require forced cooling. Air convection cooling is
sufficient for the force levels given in the specifications.
Frequency Response
The following figure shows the acceleration levels/Input voltage versus
frequency of the shaker.
Mounting Interface
The shaker has seven M6 holes for DUT and fixture connection as shown in the
following figure.
Maintenance and Troubleshooting
The DYN-PM-100 shaker is a sealed device requiring no maintenance if the operating instructions described in this manual are followed. Repair of damage to the coil, exciter body or magnet core should not be attempted. Please return the shaker to Dynalabs for proper repair.
Safety
Please ensure that this manual section is reviewed and understood prior to installation, operation or maintenance of the equipment. The danger of electrical shock or fire always exists in electrical equipment. The DYNPM- 100 PM Shaker is designed for safe operation. Safety features such as electrical insulation on outer surfaces, shaker body grounding connection are provided for safe operation of the shaker system.
