Drive coil

The polarity of both the drive coil and pick-up coil of the Mossbauer motor can be changed together without changing the performance. [Pg.31]

A typical electromechanical device for velocity modulation consists of two coils (30,32, 86-88) a drive coil across which a voltage related to the... [Pg.157]

Viscosity System. A Dynatrol viscosity system was purchased from Automation Products, Inc., Houston, Texas. The detector (Type CL-lODVT-4) is inserted in the vessel with the probe fully immersed in the process medium. The drive coil is excited at a frequency of 120 cps. This produces a pulsating magnetic field which causes the drive armature to vibrate at a frequency of 120 cps. [Pg.292]

Figure 16.25 A schematic simultaneous TGA-DTA instrument. A weight change on the sample side displaces the beam and a drive coil current returns the beam to zero. The current is proportional to the weight change and serves as the TGA signal. The temperature change between the sample and reference pans is measured by thermocouples attached to the pans. The temperature differential is the DTA signal. (Courtesy of ThermoHaake, Inc., Paramus, NJ, www.thermo.com, and Seiko Instruments, Japan.)...

Anszoer by Author Both the driving coil and the pickup coil are wound around the tubular mangeto-strictive element. The exact location and the method of winding and potting the coils is the manufacturers proprietary information. [Pg.422]

The source (and in a few cases the absorber) is mounted on the vibrating axis of an electromagnetic transducer (loudspeaker system) [ 16J which is moved according to a voltage waveform applied to the driving coil of the system. The usual velocity functions are of the triangular, sawtooth, or sinusoidal form. In special cases the source may be moved with a constant velocity,... [Pg.565]
