Structure and Application of Ohmic Servo Motor

From equipment design to installation, debugging, and maintenance, Omron has fully considered the problems faced by customers and completed the design of the 1S series servo system, committed to improving efficiency. In addition, by adopting a battery free ABS encoder, achieving security and high-speed high-precision control of the same network, the production efficiency of the equipment can be improved.

Servo motors can control speed and position accuracy very accurately, and can convert voltage signals into torque and speed to drive control objects. The rotor speed of a servo motor is controlled by input signals and can react quickly. In automatic control systems, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no self rotation phenomenon, and the speed decreases uniformly with the increase of torque.

When the servo motor receives one pulse, it will rotate by the corresponding angle to achieve displacement. Because the servo motor itself has the function of emitting pulses, every time the servo motor rotates by one angle, it will emit a corresponding number of pulses. This forms a response or closed loop with the pulses received by the servo motor. In this way, the system will know how many pulses have been sent to the servo motor and how many pulses have been received back. In this way, the rotation of the motor can be accurately controlled to achieve precise positioning, which can reach 0.001mm.
