Features ALUMINUM ALLOY MATERIAL: Made of premium aluminum alloy material, the motor has good heat dissipation, and it is lightweight, safe and reliable for long term use. LOW HEAT: 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, save energy and improve efficiency. LOW NOISE: This motor has good resistance to the low frequency resonance that plagues the traditional stepping motor, which features quieter operation. QUICK RESPONSE: The position response output is synchronized with the input command signal in almost real time. Servo control technology provides high torsion output for high speed dynamic response of the system. SPACE SAVING: The integration of motor and driver saves complicated wiring and increases the installation space of motor.
