The performance test of the actuator distinguishes between the behavior test of the drive part and the magnetic force test.
The required physical quantities are current, displacement, and force, and an ampare meter, a displacement meter, and a force meter are required for measurement.
The behavior test is a test of drive displacement, current and magnetic forces for time, in addition, requires a fast data acquisition device such as an oscilloscope.
The magnetic force test is a test to measure the magnetic force against the displacement and the magnetic force against the current. To do this, the AFT (Actuator Function Test) of open source project provides open source measurement software and hardware.
