Courtesy: STMicroelectronicsPrecision movement and positioning systems used in industries such as automated manufacturing and pharmaceutical production can be quieter, smaller, lighter, simpler and more efficient with the cSpin single-chip digital motion controllers by STMicroelectronics (NYSE: STM).

cSpin also allows precise control over rotation speed, which is particularly important for repeatable, accurate mixing of liquids in applications, such as handling of medical samples. For all applications, the smooth and noiseless operation delivers advantages for users, especially in quiet environments such as laboratories or on hospital premises.

cSpin micro-stepping controllers for 2-phase stepper motors provide communication with the main system uses high-level commands via a standard Serial Peripheral Interface (SPI). The on-chip gate-driver circuitry, for the motor’s power stage, can operate from 8 V to 85 V, which allows applications to scale smoothly over a wide power range up to 300 W. ST’s digital motion engine is optimized to overcome known challenges such as avoiding resonance to ensure exceptionally smooth and quiet motor operation.

ST's cSpin family does not require motor-control software and simplifies system design by performing all calculation, control and interfacing functions in a single chip. Competing solutions require software and multiple discrete chips, which designers must combine before starting to develop their applications. With cSPIN, projects can begin using an ST evaluation board containing the control IC, which can be connected immediately to a stepper motor enabling rapid prototyping.
