Precision Control Methods For High-Power Stepper Motors In CNC-Machine Applications

I

ntroduction:

Manufacturing businesses worldwide rely heavily on CNC machine tools to produce parts to high standards of accuracy and at high throughput rates. Equipment suppliers are under pressure to deliver higher performing equipment, offering faster turning and feed-in speeds, quicker acceleration and fast-acting safety features.

Another key trend in the market for CNC equipment is toward multi-axis and multi-task machines to reduce human intervention when producing complex components. At the same time, there are perennial demands to reduce equipment costs, increase reliability, and maximise work handling capability within compact overall dimensions.

In the design of stepper-motor control electronics, increasing system-on-chip integration by combining the control logic and high-power output stage in a single chip can help equipment designers satisfy these demands. Innovative process technology capable of supporting high motor current and voltage is critical, to satisfy the demands of a broad spectrum of industrial users.
