The marches in mechatronic science and engeenering enable us to create and produce high quality progammable sport and rehabilitation equipment. In study presented we analyze modeling of trainer’s direct current drive control, which is designed to control realization with programmable microcontroller. There we introduce block scheme of the drive’s model, working in isokinetic and isotonic mode in the training equipment, and the main mathematical dependences. Executing drives work simulation according to this model we have chosen optimal rates. Here we present the samples of characteristics which were got by simulating.
