Servo motor is prone to low-frequency vibration at low speed. The
vibration frequency is related to the load condition and driver
performance. It is generally considered that the vibration
frequency is half of the no-load take-off frequency of the motor.
This low-frequency vibration phenomenon determined by the working
principle of servo motor is very unfavorable to the normal
operation of the machine. When the servo motor works at low speed,
damping technology should generally be used to overcome the
phenomenon of low-frequency vibration, such as adding damper on the
motor or subdivision technology on the driver. At present, most
servo motors used in computerized embroidery machines are five
phase hybrid servo motors. The purpose is to reduce the step torque
angle and improve the control accuracy by using stepping motors
with high phase number, but the improvement of performance obtained
by this method is limited And the cost is relatively high. Using
subdivision drive technology can greatly improve the operation
quality of servo motor, reduce torque fluctuation, suppress
oscillation, reduce noise and improve step torque resolution. If
the reactive servo motor is adopted, the performance can be
significantly improved and the cost of the product can be greatly
reduced. Servo motor is widely used in the industry. The following
is a brief introduction: 1 It is widely used in ATM machines,
inkjet machines, lettering machines, photo machines, spraying
equipment, medical instruments and equipment, computer peripherals
and mass storage equipment, precision instruments, industrial
control systems, office automation, robots and other fields. It is
especially suitable for applications requiring stable operation,
low noise, fast response, long service life and high output torque.
2. Servo motors are widely used in textile machinery and equipment
such as computerized embroidery machines. These stepping motors are
characterized by low torque, frequent start-up, fast response, low
running noise, stable operation, good control performance and low
cost.
