Product Description
Resolver is a kind of electromagnetic sensor. It is a kind of AC motor to measure the rotation angle signal and the rotation axis position, speed and angular speed of the rotating object, composed of stator and rotor. As the primary side of the transformer, the stator winding receives the excitation voltage, and the excitation frequency is usually 400 /1800/ 3000/ 10000Hz, etc. As the secondary side of the transformer, the rotor winding obtains the induced voltage through electromagnetic coupling.

Advantage |
Disadvantage |
| Optical encoder |
Simple circuit design, high noise tolerance, easy toimprove the accuracy. |
Not good in mechanical abuse and high temperature,easy to be
interfered by radiation, high maintenance frequency, incapable to be
used in severe working environment. Highest price. |
| Hall Sensor |
Low price. |
Low discrimination limits the control accuracy, and the Hall component will weaken after being heated for a long time, thus the service life is not long. |
| Resolver |
Resistance to impact, high temperature and oil stains, high reliability, long life, etc. The accuracy is comparable to the optical encode. |
The output is analog signal, the decoding is more complicate. |
