Features Motor and Driver: The integration of closed loop servo motor and 3D printer driver will save complex wiring and increases the installation space of the motor. Premium Control: The position response output is almost synchronized with the input command signal in real time. Servo control technology provides large torsion output, so that the system has high speed dynamic response. Large in Torsion: The high speed performance of the hybrid servo drive system is more than 30% higher, and the effective torsion is increased to more than 70%, so that the motor can maintain high torsion operation. Stable Operation: The space vector current control algorithm and vector smoothing filter technology based on feedback encoder have a good resistance to the low frequency resonance that plagues the traditional stepping motor. Great Efficiency: Adjust the current in real time according to the actual load, reduce the heating, close to 9% of the torsion output capacity, play a greater energy conversion in a compact space, and save energy and efficiency.
