Brushless motor is small in size, light in weight and large in output. Liaoyang outgoing shaft motor has fast response, high speed, small inertia, smooth rotation and stable torque. The control is complex, easy to realize intellectualization, and its electronic commutation mode is flexible, which can be square wave commutation or sine wave commutation. The motor is maintenance free, with efficiency of * * *, low operating temperature, low electromagnetic radiation and long service life. It can be used in various environments. AC servo
