FAQ
Q1：What is a resolver and where are it used?
A resolver is a brushless angle feedback system based on the principle of electromagnetic induction, producing an absolute analog signal. It is primarily used to control the speed of servo motors. Compared to rotary encoders, resolvers have a wider range of applications (e.g., robotics, automotive, transportation, aerospace, and military). Depending on the design, the operating temperature range can be -55°C to 155°C. Resolvers are unaffected by radioactivity and can be used in absolute vacuum (space). Maximum speeds can reach 90,000 rpm.
Q2：Why did the resolver control unit report an error during the first test?
Are the frequency, input voltage, turns ratio, and current loss of the resolver consistent with the values set by the control unit。Stranded cable (input voltage, Sin, Cos)
Is there any electromagnetic interference (from motor brakes, excessively long cables)
Q3：Why can resolver products in the same series have different specifications?
Because servo controllers commonly found on the market come in different frequencies and voltages. The data on resistance and phase shift in the three tables correspond to various resistances, impedance strengths, and phase shifts under two to three different input frequencies and feedback voltages. We provide you with the necessary information to help you select the correct analog-to-digital converter or appropriate control components.
Q4：How to install and secure the stator and rotor of a rotary transformer?
The stator is mounted to the bearing housing of the motor. It is secured using clamps or snap rings.
The rotor is typically glued to the rotating shaft. For some special shapes or security applications, the rotor can be secured to the shaft using axial screws. For larger shaft diameters, the rotor is secured with radial clamping screws (e.g., set screws).
Q5：What is the accuracy of the resolver?
Standard resolvers have an absolute measurement accuracy of ±10'. In most cases, this accuracy is sufficient for speed control units with typical systems. For applications requiring higher precision positioning, we also offer resolvers with absolute measurement accuracies of ±6' and ±4'.
