Future Electronics, a global leading distributor of electronic components, promotes rugged, accurate commutation encoders from CUI Inc which drastically reduce assembly time on BLDC motors.
CUI Inc's next-generation modular encoder series generates standard U/V/W commutation signals for vectoring current to brushless motors.
Positional information for the AMT31 series is generated using CUI's patented, capacitive code generation system coupled with a proprietary ASIC. The technology makes the encoder ideal for use in brushless dc motor applications subject to vibration and contaminants - such as dust, dirt and oil - that typically stop optical encoders from working effectively. The AMT31 series also delivers exceptional accuracy figures of +/- 12 arcmin (±0.2 mechanical degrees).
Thanks to the digital nature of the encoder design, the AMT31 series incorporates a One Touch Zero™ feature, allowing for significant time saving during the motor installation process. Installing a commutation optical encoder onto a brushless dc motor (BLDC) can be an iterative and time-consuming process as the optical disk must be physically and precisely rotated to align with the correct motor windings. Once aligned, the assembly must then be checked via back EMF to ensure mounting accuracy and this process can take upwards of 15 minutes per motor. The AMT, being ASIC and MCU based, reduces this time consuming process to a few seconds via the One Touch Zero feature, saving time and cost during the manufacturing process.
Commutation output can accommodate brushless motors with 2, 4, 6, 8, 10, 12 or 20 pole pairs, selectable from the factory or via CUI's AMT Viewpoint™ graphical user interface. The AMT31 also offers supplementary incremental A, B, and Z channels for various servo positioning and startup sequences. 20 programmable resolutions are available with a range of 48 to 4096 PPR, again adjustable at the factory or via CUI's AMT Viewpoint. For quick analysis during design or in the field, the AMT31 implements an onboard diagnostic system, allowing access to a range of parameters.
