RDC GX2S1205 (compatible with AD2S1205) in the new energy vehicle motor system applications

RDC is a kind of AC micro motor that can output electrical signals as a function of rotor angle or position, mainly used in angular position servo control system or motion servo control system, as the sensing and measuring of angular position, it can be used to accurately measure the rotor position signals, so as to improve the control performance of the motion servo control system, and it has been widely used in the field of motor control.

In the new energy vehicle motor rotor position decoding system, the RDC GX2S1205 is used to convert the analog signal output from the resolver into a digital signal for processing by the DSP.The GX2S1205 has a resolution of 10 to 16 bits, a maximum accuracy of ±10 arc minutes, and a digitally variable R/D converter with a reference oscillator, which has been certified for automotive applications.

Product features of GX2S1205 (AD2S1205 compatible) for new energy vehicle motors:

1, Ratiometric Tracking ConversionThe Type II tracking loop is capable of continuously outputting position data with no conversion delay. It can also suppress noise and provide harmonic distortion tolerance of the reference and input signals

2, system fault detection. Fault detection circuits can detect rotary signal loss, out-of-range input signals, input signal mismatch, or loss of position tracking. Each fault detection threshold can be individually programmed by the user to be optimized for a specific application.

3. Input signal range. The sine and cosine inputs support differential input voltages of 3.15 Vp-p ±27%.

4, Programmable excitation frequency. The excitation frequency can be easily set to multiple standard frequencies in the range of 2kHz to 20kHz.

5, 3 formats position data. 10-bit to 16-bit absolute angular position data can be accessed through the 12-parallel port or 3-wire serial interface. Incremental encoder emulation is available in standard A-quad-B format with direction output.

6. Digital speed output. 10-bit to 16-bit signed digital speeds can be accessed via the 12-bit parallel port or the 3-wire serial interface.

It can be seen that the rotary digitizer GX2S1205 has good reliability, strong anti-interference ability, fully able to meet the requirements of high-speed motor control systems and vehicle environment applications. GX2S1205 has a certain price advantage, GXSC can provide stable technical support and supply channels.
