  • Patent number: 9041336
    Abstract: A controller for a substrate transport apparatus. The controller includes a first system and a second system for at least partially controlling a movement of a motor of the substrate transport apparatus. The first system is configured to control the movement of the motor based upon a signal from a position sensor. The position sensor outputs the signal based upon a position of a rotor of the motor relative to a stator of the motor. Torque output of the motor is at least partially controlled based upon the signal from the position sensor. The second system for at least partially controlling the movement of the motor is based upon expected disturbances during movement of an arm of the substrate transport apparatus by the motor, where the second system is configured to at least partially increase and/or decrease the torque output of the motor by first system.
