Rotary encoders
Incremental
Incremental transducers of angular motion (incremental rotary encoders) are designed to transmit information about the direction, angle of rotation and angular velocity of a positionable object. An encoder generates periodic signals that are registered and interpreted by a receiving device as the required parameters of the positionable object. The number of periods is proportional to the rotation angle of the shaft.
Absolute
Absolute transducers of angular motion (absolute rotary encoders) are used to determine the shaft position of a positionable object. Each position of the shaft corresponds to a unique code that can be read immediately after power is applied to the encoder. This makes it possible not to lose information about the motion made by the positionable object at the moment when the measuring system is turned off. Some models of absolute encoders are equipped with a mechanical gearbox that allows to determine not only the position within 360°, but also the number of complete revolutions.
Resolvers
Resolvers (rotary encoders based on a rotary transformer) are designed to convert the rotation magnitude into an electrical voltage. The amplitude of the voltage is proportional to the rotation angle of a positionable object. Resolvers are similar in design to AC-excited synchronous motors and are therefore suitable for harsh environments.
Special
Here are specialized encoders designed to solve a specific range of tasks. These are encoders for elevator winches, gears, electronic flywheels and more.
