Wholesale printer motor need to pay attention to the low frequency characteristics of the motor:
The stepper motor is prone to low frequency vibration at low speed. The vibration frequency is related to the load condition and the performance of the driver. It is generally considered that the vibration frequency is half of the no-load starting frequency of the motor.
The low frequency vibration which is determined by the working principle of the stepper motor is very unfavorable to the normal operation of the machine. When the stepper motor works at low speed, damping technology should be used to overcome low frequency vibration, such as adding dampers on the motor, or using subdivision technology on the driver.
The AC servo motor runs very smoothly and does not vibrate even at low speed. The AC servo system has the resonance suppression function, which can cover the mechanical rigidity deficiency, and the system has the internal frequency analysis function, which can detect the mechanical resonance point, which is easy to adjust the system.
3. Different moment-frequency characteristics:
The output torque of the stepper motor decreases with the increase of the speed, and decreases sharply at a higher speed, so its maximum working speed is generally 300 ~ 600RPM.
The AC servo motor is a constant torque output, that is, within its rated speed (generally 2000RPM or 3000RPM), it can output rated torque, and above the rated speed is a constant power output.
