Abstract
A system for reducing torque disturbance includes a motor mechanically coupled to an endless belt. The motor is operable to drive the belt, and the belt has a seam that causes a torque disturbance to the system. The system includes a data structure having a set of values that indicates an amount of compensation for reducing the torque disturbance and a controller electrically coupled with the motor. The controller is configured to control the motor and reduce the torque disturbance based on the set of values in the data structure.
Claims19
A system for reducing torque disturbance, the system comprising:
- a motor mechanically coupled to an endless belt, the motor being operable to drive the belt, and the belt having a seam that causes a torque disturbance to the system;
- a data structure having a set of values that indicates an amount of compensation for reducing the torque disturbance;
- and
- a controller electrically coupled with the motor, the controller being configured to control the motor and reduce the torque disturbance based on the set of values in the data structure,
- wherein the belt includes a position marker at a distance from the seam, the controller being configured to determine when the torque disturbance is expected to occur based on sensing of the position marker and said distance.
A method for reducing torque disturbance, the method comprising:
- controllably operating a motor to drive an endless belt in a cyclical manner;
- determining when a seam of the belt is expected to cause a torque disturbance to a system;
- determining an amount of compensation for reducing the torque disturbance;
- and
- controllably operating the motor based on the amount of compensation to reduce the torque disturbance.
A method for reducing torque disturbance, the method comprising:
- controllably operating a motor to drive an endless belt having a seam in a cyclical manner;
- sensing a position marker associated with the belt;
- determining when a torque disturbance is expected to occur based on said sensing of the position marker and a distance between the position marker and the seam;
- determining an amount of compensation for reducing the torque disturbance;
- and
- controllably operating the motor based on the amount of compensation to reduce the torque disturbance.
A recording medium having computer executable program code for a method of reducing torque disturbance, the method comprising:
- controllably operating a motor to drive an endless belt in a cyclical manner;
- determining when a seam of the belt is expected to cause a torque disturbance to a system;
- determining an amount of compensation for reducing the torque disturbance;
- and
- controllably operating the motor based on the amount of compensation to reduce the torque disturbance.
A printing system, comprising:
- a belt having two ends joined together to form a seam;
- a motor mechanically coupled to the belt, the motor being operable to drive the belt;
- an acoustic transfer assist device configured to transfer an image from the belt to a medium, the assist device including a vacuum source for drawing the belt toward the assist device, the vacuum source and the seam cooperating to cause a torque disturbance to the system;
- a data structure having a set of values that indicates an amount of compensation for reducing the torque disturbance;
- and
- a controller electrically coupled with the motor, the controller being configured to control the motor and reduce the torque disturbance based on the set of values in the data structure,
- wherein the belt includes a position marker at a distance from the seam, the controller being configured to determine when the torque disturbance is expected to occur based on sensing of the position marker and said distance.
