D-Series Inductive Rotary Encoders_Mosrac Motor Co., Ltd.

D-Series Inductive Rotary Encoders

The product includes three parts: a stator and two rotors.

It is perfect for compact applications where space is tight and can be easily installed in robot joints or multi-axis automation systems.

The D-series encoder has two separate position-detection and signal-output systems, allowing for redundant operation and greatly increasing reliability.

Customization options are available to best suit customer needs.

Direct drives need high-quality position signals to ensure optimal performance. Perfect measuring signals can enhance the surface quality of machined workpieces, reduce the machine frame's vibrations, minimize velocity-dependent motor noise, and prevent excessive heat generation in the motor.

Mosrac recommends using a magnetic encoder to enhance the accuracy, speed stability, and thermal behavior of direct drive axes. Because there is no mechanical transmission between the encoder and the feed unit, the position signals are not susceptible to inaccuracies or delays.

Custom combinations are available on request and contact us.
