Accelus Card
The Accelus servo amplifier drives DC brushless motors in position, velocity, or torque modes with 100% digital control. New-generation DSP technology provides unprecedented bandwidth and enables advanced commutation and tuning algorithms. 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. Space-vector modulation produces higher speeds than sine-pwm modulation from the same buss voltage.
