AMM80 is the latest project in the range of Lika Electronic's optical kit encoders. AMM80 is a frameless and bearingless optical encoder, i.e. it is not equipped with shaft, bearings, flange, and housing. It is designed to have the smallest footprint, very low profile, minimum weight, high resolution, and fine accuracy. It is ideally suited for direct integration into high performance and space critical applications such as robots, robotic joints, hollow shaft motors (direct drive torque motors, brushless motors, stepper motors), electromedical devices, and a variety of OEM motion control applications. It is also engineered in an extensive choice of mechanical and electrical options and can be customized to meet individual requirements. This compact, slim, and lightweight encoder has a large through hollow shaft that fits diameters up to 45 mm / 1.77” and common motor sizes. Applications where hardly accessible space and minimum weight are crucial also benefit from its simple and quick assembly with pilot flange or two precision pins. It does not require calibration. Its operation is non contact and there are no components subject to wear and fatigue. AMM80 kit encoder provides position feedback via SSI, BiSS C, and RS-485 interfaces. The resolution is 23 bit singleturn (8,388,608 cpr) and 16 bit multiturn (65,536 rev.), the accuracy is ±0.010°. An additional incremental track offers 1,024 Sine/Cosine 1Vpp signals for speed feedback and interpolation needs. Lika Electronic has long-standing experience in the encoders and position measurement industry and develops customer-specific solutions that meet individual size, shape, resolution, and connection needs.
