The development of new accurate methods of electric synchronization of multimotor of electric drives will give a push to create a gearless (direct-drive) multimotor electric drive that will lead to reduction in the size of equipment and improving its reliability (Lemmens & Driesen, 2012).
For example, multimotor electric drives of hoisting mechanisms (Jeftenic et al., 2001), (Jeftenic et al., 2006), (Nebojsa et al., 2009).
Prospects of Development of the Theory and Practice of Interconnected MultiMotor Electric Drives
