Servo motor is a generator that controls the operation of mechanical components in the servo system. It can supplement the indirect variable speed working device of the motor. It has very high control speed and accuracy, and can respond quickly after receiving the signal. When the voltage drops0When the servo motor stops running, its speed and torque will gradually decrease.
The main components of an AC servo motor are a motor and a driver. The motor part is composed of an electromagnetic winding that can generate a magnetic field and a permanent magnet rotor or a rotating electric drive. The composition of the rotor is mainly silicon steel sheet and permanent magnet,There are also accessories for fixing the permanent magnets to the rotor. The materials of these accessories are generally epoxy resin, glass fiber and other non-magnetic materials. The biggest difference from ordinary motors is that there are permanent magnets on the rotor.
From the basic structure of the servo motor system,The servo system mainly consists of three parts. Controller, power drive device, feedback device and motor. The controller can detect the actual operating difference by feedback according to the corresponding signal value of the system, and adjust its control amount accordingly; the power drive device is generally used as the main circuit of the system,The electric energy is applied to the motor according to the specific value of the control amount, thereby adjusting the torque of the motor and providing the required electric energy according to the requirements of the motor. The electric motor provides the corresponding rotational energy according to the amount of electric energy.
