NEMA23 RS485 Stepper Motor Driver (AR57)
Product Link
[edit]Description
[edit]The NEMA23 RS485 Stepper Motor Driver (AR57) is a high-performance stepper drive with RS485 MODBUS-RTU communication for the NEMA23 (57mm) frame size. Designed for industrial automation, it can drive NEMA23 stepper motors in either standalone driver configuration or as part of an integrated motor assembly.
Powered by a 32-bit DSP processor, the AR57 delivers smooth current control with advanced algorithms for low noise, low vibration, and efficient operation. The MODBUS-RTU interface allows direct connection to PLCs and industrial controllers, enabling comprehensive motion control over a single RS485 bus.
Multi-axis networking with daisy-chain topology reduces wiring complexity in systems with multiple motors. Each driver can be individually addressed and configured.
