Industrial Router Crystal 3.2*2.5mm 3225 26M (26.000MHZ) 12PF 10PPM 20PPM 30PPM

Factory direct 0603 emerald green, 0603 green (0.6 thickness) a lot of low price

The probe domestically produced P02-B needle nickel-plated needle body diameter is 0.68. The length of the spring needle is

inductance

In the figure, the output signal of the resolver is sent to AD2S83, DATA [0~16] is the digital output of AD2S83; SC1 and SC2 select the output precision of AD2S83, and select according to the maximum speed of the motor. In the design process, the TMS320F2812 is fully utilized with rich resources and many pins. It controls the accuracy selection bits and expands the use of the object. The maximum speed of the servo motor of this system is 1 500 r/min, and the final selection of AD2S83 is 14 Bit precision.
