A power cable and a communication cable connecting between a plurality of motor units , each of which includes a motor , an inverter and a communication part , extend successively from a power supply and a network control computer , respectively, to the respective motor units in such a manner that the motor units are connected with each other in a cascade manner from a preceding one to a following one. In addition, each of the motor units includes a connection board on which an inverter and a communication part are installed. The power cable and the communication cable are connected with the respective inverters and the respective communication parts through connection terminal blocks, respectively, each of which includes a cable connector for connecting the cables from a preceding motor unit and the cables to a following motor with each other, and a terminal block fixture for detachably fixing the associated connection terminal block to the associated inverter or the associated communication part.
