Selection Requirements for Resolvers

1. Excitation Voltage (Rated Excitation): 4Vrms, 7Vrms, 10Vrms, etc 2. Excitation Frequency: 400Hz, 1kHz, 5kHz, 10kHz; industrial servo and new energy applications usually use 5kHz-10kHz. Higher frequency means faster response, but cable parasitic capacitance has a bigger effect. 3. Transformation Ratio (Turns Ratio): Output voltage / Excitation voltage, determines SIN/COS output amplitude; output amplitude should be within the decoder chip's optimal input range. Common value in new energy vehicles is 0.286. 4. Input Impedance: Impedance on the excitation side, should match the driving capability; if impedance is too low, it overloads the excitation chip. 5. Phase Shift: Phase difference between output and excitation, generally 3-12° electrical; too large increases decoding errors. 6. Output: Two differential analog signals, SIN and COS; for long distances, differential output is preferred for better interference resistance.
