Residual voltage
Residual voltage test is used to detect the presence of residual voltage in a system, after the main source of power is disconnected.
Prove – motori brushless
Within this section you can consult the list of all the tests performed by Risatti Instruments in the field of tests for brushless motors.
AC Dielectric Strength Test
The AC dielectric strength test is performed by setting an acceptability threshold of the maximum current.
DC Dielectric Strength Test
The DC dielectric strength test is carried out when there are very significant capacitive currents.
Electrical resistance test
Testing the electrical resistance of a winding is essential and is performed to measure the resistance of a winding.
BEMF (Back EMF)
The BEMF (back EMF) test measures the induced voltage generated between the terminals of the motor rotated by external drive.
Hall encoder test and Hall sensor
The encoder test allows checking the correct connection of the Hall UVW sensors and phases A and B on the connector.
Partial Discharge analysis (PD)
Partial discharges (PD) are electrical discharges localized in the dielectric insulation, limited only to a part of the dielectric material.
DC insulation resistance test
The DC insulation resistance test evaluates the quality of the insulators, the possible presence of humidity and pollution.
