Buy motor equipment, brushless motor features: small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, torque stability.The control is complex, easy to realize intelligent, and the electronic commutation mode is flexible, which can be square wave commutation or sine wave commutation.Maintenance-free motor, high efficiency, low operating temperature, small electromagnetic radiation, long life, can be used in a variety of environments.
2. AC servo motor is also brushless motor, divided into synchronous and asynchronous motor. At present, synchronous motor is generally used in motion control, and its power range is large.Large inertia, low maximum rotation speed, and decreases rapidly with power increase.Therefore, it is suitable for low speed and smooth running applications.
3. The rotor inside the servo motor is a permanent magnet, the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field, and the rotor rotates under the action of this magnetic field. At the same time, the encoder with the motor gives feedback signal to the driver, and the driver compares the feedback value with the target value to adjust the rotation Angle of the rotor.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 sinusoidal wave control, torque ripple is small.The DC servo is a trapezoidal wave.But DC servos are simpler and cheaper.
