Ball Screw Drive Linear Stepper Motor is a high performance drive assembly integrating Ball Screw + Stepper Motor by coupling-less design. Stroke can be adjusted by cutting off the shaft end, and by mounting the motor directly on the shaft end of the ball screw, an ideal structure is realized where the axis of the ball screw becomes the axis of rotation of the motor. In order to meet customers’ short-term delivery needs, KGG prepares standard stock items of external linear actuators (Ball Screw/Sliding Screw drive optional) (GSSD series).
Features:
Database Compensated Control
The servo is not controlled by a single micro-stepping control. The motor is equipped with an encoder and a memory original based on the encoder position information with a resolution of 400 pulses per revolution and current feedback. In addition, the motor intrinsic data has been saved in the memory at the factory, and high-speed and high-precision positioning of the target position is achieved by the precision database compensation control method when the motor is driven.
Sampling of Motor Characteristic Data
Cogging torque and torque pulsation caused by the processing and assembly accuracy of the motor are important causes of low vibration and high-precision positioning. The servo can accurately measure and grasp these motor intrinsic data affecting control and positioning accuracy during micro-stepping control, and database them as the optimum current waveform.
Saving Data to Memory
Sampling data is saved in the memory inside the motor and transferred to the driver via the encoder cable when the power is turned on. This enables any combination of driver and motor.
High-precision Positioning
In addition to refining the command resolution as in micro stepping control, the actual stopping accuracy has been increased to a level equivalent to a 10,000 pulse encoder. In addition, it is possible to achieve equally spaced positioning in pulse units, which is not possible with micro stepping control.
Realised Low Vibration Operation
Motor vibration can be greatly eliminated by applying an optimum compensation current command at high speed during clicking action. As with stepping motors, no tiny vibrations like those of servo motors are generated when the motor stops.
Settling Time
Settling to within ± pulses of 12,800 steps/revolution takes only 1 ms.
Excellent performance in applications requiring high-cadence operation.
Ample Torque Reserve
No misalignment, and can be operated continuously at 100% load without consideration of torque margin.
Stepping Torque Control
5-step torque control is possible along with position control.
Any torque value can be set during Point Table operation.
Realisation of Automatic Tuning
The real-time auto-tuning function automatically simulates changes in inertia and rigidity of machinery that cannot be driven smoothly by conventional auto-tuning methods, maintaining optimum responsiveness and stability at all times.
