Characteristics of Brushless DC Servo Motors
Small rotational inertia, low starting voltage, and low no-load current; Abandon contact commutation system, greatly increasing motor speed, with the maximum speed reaching up to 100,000 rpm; In performing servo control, brushless servo motors do not require encoders to achieve control of speed, position, and torque; There is no brush wear, in addition to high speed, it also has the characteristics of long lifespan, low noise, and no electromagnetic interference.
Characteristics of Brushed DC Servo Motors
1. Small size, fast action, fast response, high overload capacity, wide speed regulation range
2. Large low-speed torque, small fluctuations, stable operation
3. Low noise, high efficiency
4. Feedback from rear encoder (optional) forms the advantages of DC servo
5. Wide voltage range, adjustable frequency
