    Tips: What are the types of servo motor?

    Servo motors are mainly classified into AC servo motors and DC servo motors. AC servo motors are also brushless motors, which are divided into synchronous and asynchronous motors. At present, synchronous motors are generally used in motion control. They have a large power range and can achieve great power. Large inertia, low maximum rotation speed, and rapid decrease as the power increases. Therefore, it is suitable for low-speed and smooth-running machines. 

    DC servo motors are divided into brush and brushless motors. Brushed motors have low cost, simple structure, large starting torque, wide speed range, easy to control and maintain (changing carbon brushes), it will generate electromagnetic interference and have specific requirements for the environment. The brushless motor is small in size, light in weight, large in output, fast in response, high in speed, small inertia, smooth in rotation, and stable in torque. The control is complex and easy to realize intelligence, and its electronic commutation method is flexible, and it can be square wave commutation or sine wave commutation.

    Existing reviews of 50W AC Servo Motor, 0.16 Nm, 3000 rpm
    Perfect servo motor
    The appearance of the AC servo motor is clean and beautiful, the workmanship is very good, and no flaws are found. The size is also very suitable, I have been looking for this one for a long time, I love it!

    Two questions about 50W servo motor
    1. Can one drive control two 50W servo motors?
    2. And does your 50W servo motor box incorporate cables?
