DC servo-amplifier Accelus ASC series

brushlessstepperdigital

The ASC delivers high-performance control of brushless and brush motors in a cost-effective card. A panel mounted version is also available. Torque and velocity modes are complemented by Step/ Direction position mode. Feedback is incremental encoder and digital Halls.

Commutation is sinusoidal using encoder feedback from the motor. Hall signals are used for phase-initialization and phase-correction eliminating motor hunting after power-up. Advanced field-oriented-control ensures the highest motor torque over a wide speed range, minimizing motor heating and maximizing efficiency. Digital control algorithms transform AC stator currents into direct and quadrature components. The torque-producing quadrature current is controlled by the current loop, and the direct component is driven to zero eliminating losses from current that doesn’t produce torque.
