PURPOSE:To reduce the irregularity of sharing loads at two motors by mechanically coupling directly two motors, and connecting the windings of the two motors in series to supply power via an inverter. CONSTITUTION:The windings 4a, 4b of motors 2a, 2b are connected in series via connecting wirings 5, and supplied with power via an inverter 1a. Motors 2a, 2b are mechanically coupled directly. Thus, the values of currents flowing to the motors 2a, 2b are always the same, and the irregularity of sharing loads at both the motors is reduced. |
