Annotation: The paper gives reasons for conducting experimental works to determine lateral force caused by eccentricity and skew of SRM thrust vector, considers the configuration of fixed test stand for respective experimental works with vertical position of motor axis and describes the fixed test stand operation principle.

Annotation: The advanced design of SRM test rig is considered the use of which improves the quality of measurement of motor power parameters and increases the amount of test data. It is shown, due to which this was achieved. The technique is proposed for assessment of rig operation stability when measuring the lateral thrust.
