I have a shielded cable connection from the drive to the motor. The earth connection on the motor end is ground to the casing with the screen from the cable and the earth connection is also ground at the drive end with the screen open.
I am using a 240vac to 115 VAC stepdown transformer as...
hi bartos,
the magnetic sensor is mounted on a linear actuator driven by the stepper motor. There is a seperate amplifier that energises the sensor and receives the signal.
the supply filter that I am using is a stand line filter for mains power supply, for eliminating voltage spikes and to...
I am trying to build a automated NDT device using an electromagnetic sensor (pulse receive system) driven in a single axis linear actuator by a Parker stepper motor. However, whenever the motor is switched on, the magnetic sensor picks up a noisy inteference.
The supply to the motor drive (Zeta...
WIM32,
I have done some work on meassuring damping properties of materials and the two techniques that gives you a reasonable estimate of damping is the constrain beam method and the DMTA (Dynamic Mechanical Thermal Analyser). I have used the latter quite extensively to measure damping...
