In their way of operation, electric motors are in themselves electromechanical systems, which to the greatest extent allow realizing the concept of building a mechatronic system. This paper presents a microprocessor-based bench for measuring the current and angular velocity of a brushed DC motor as a function of armature voltage at no-load. The report shows the use of the bench to calculate the parameters of the DC motor and to evaluate its condition. An analysis is made of the condition of the engine and the modes in which it is most efficient.

Maintaining the set sowing rate is important to obtain an accurate number of plants and guarantee good yields. This can be achieved by mechanical systems – variators and gear reducers or by electric drive (mechatronic systems). The object of the present work is the device of a mechatronic system for setting and maintaining the sowing rate when sowing cereals. Dependencies are derived for determining the transfer function in the control mechatronic system. Its principle and structural schemes are presented
