Encoders

An encoder is an electrical device that can convert the motion of a mechanical shaft or any other physical input into a digital output. This digital output can then be used for various applications such as controlling position, measuring speed, and monitoring end points of a system. The 61S128-2-020 is an example of an encoder specifically designed for servo motor control.

61S128-2-020 Application Field and Working Principle

The 61S128-2-020 is a resolver-based servo motor encoder that is widely used in applications where precise motor control is required. It can be used in robotic arms, automation systems, precision motion system, and other industrial automation systems.

The encoder works on the principle of using a Synchro or Resolver as its main sensing element. The Resolver is composed of two sets of stator coils, positioned at 90º angles to one another, and a rotor containing a set of winding coils inside. The stator is stationary and the rotor spins in accordance to the motor speed. A signal is then generated which the encoder reads and converts into a voltage proportional to the motor speed.

The 61S128-2-020 also features a transmitting element, which fixedly mounted onto the motor and connected to the rotor. The transmitting element sends out two signals, one signal containing information on the position of the rotor, while the other signals contains the speed information. The signals are sent to a controller which then uses the signals to control the motor.

Advantages of 61S128-2-020

The main advantage of the 61S128-2-020 is its ability to accurately measure motor speed and position. This increases the accuracy of the operation of a system, resulting in precise control. Furthermore, the encoder can also detect motor stalls and sudden changes in motor speed. This can be important for controlling applications that need to monitor changes in speed or performance.

The 61S128-2-020 can also provide a speed feedback, making it suitable for use in applications that require precise speed control such as CNC machines and robot arms. The encoder is also designed to be reliable and durable, providing an extended life span of up to 5 years.

Conclusion

The 61S128-2-020 is an encoder specifically designed for servo motor control. It works on the principle of using a Synchro or Resolver as its main sensing element, sending signals to a controller to accurately measure motor speed and position. The advantage of this encoder is that it can provide precise monitoring of motor performance, making it suitable for use in various applications that require precision control.
