Description
Additional Information
the rotor inside the servo motor is a permanent magnet, the driver controls the U / V / W three-phase power to form an electromagnetic field, the rotor in the magnetic field under the action of rotation, while the motor comes encoder feedback signal to the driver, the driver feedback value Compare with the target value and adjust the angle at which the rotor rotates. The accuracy of the servo motor depends on the accuracy of the encoder (number of lines).
AC servo motor and brushless DC servo motor in the functional difference: AC servo is better because it is a sine wave control, torque ripple small. DC servo is trapezoidal wave. But the DC servo is relatively simple and cheap.
