1. A centralized motor controller for receiving commands from an application system controller and for controlling operations of a plurality of independent motors, the centralized motor controller comprising:

  • a) a power supply;

    b) a microprocessor; and

    c) an interface circuit for motor control, the interface circuit for motor control comprising at least two inverter units and two rotor position detection units;

    whereinthe power supply supplies power for each circuit part;

    the motors are controlled by the microprocessor via the interface circuit for motor control;

    a number of the motors is equal to or more than three, in which, at least two of the motors are permanent magnet synchronous motors in the absence of a motor controller;

    the permanent magnet synchronous motors are driven by the microprocessor via the inverter units, respectively; and

    rotor position data of the permanent magnet synchronous motors are transmitted to the microprocessor via the rotor position detection units, respectively.
