CUI has introduced the AMT303LD encoder series that generates U, V, and W commutation signals for vectoring current to brushless motors. The resolution of the encoders can be set through the AMT303 demo kit. The commutation output can accommodate brushless motors with 2, 4, 6, 8, 10 or 20 pole pairs and is also selectable through the AMT303LD demo board, which is included in the kit. The kit also includes interface cables, documentation software and a power supply. The encoders offer complementary incremental A/A, B/B and Z/Z channels for servo positioning and start-up sequences. They also have nine mounting patterns and 10 bore sizes to accommodate many standard motors, says the company. The encoders generate position information using the capacitive code generation system. The encoders consume a maximum current of 10mA at 5V DC. Zero position may be set by the demo board's OTZ module.
