Incremental encoder and resolver

Incremental path-measuring and angle-measuring systems are used on electro-mechanical actuators as:

  • feedback from transmitters for controlling the speed and position of three-phase motors or servo-motors in the converter operation
  • sensors for controlling the speed of direct-current motors
  • economical and high-resolution path-measuring sensors
  • sensors for precise, direct-current or angular control during the synchronous running of several drives with frequency converters in master or slave operation.

The reference travel to a limit switch is required for path-measuring.

The incremental transmitter is usually attached to the shaft’s second end on the motor shaft in direct-current or three-phase motors . A resolver – which can also be used for path-measuring and balancing the incremental transmitter – is always integrated into the basic equipment for servo-motors.
