If you dont define a resolver for a particular field, Apollo Server automatically defines a default resolver for it.
It can populate that data in any way you define, such as by fetching data from a back-end database or a third-party API. The secondary windings, which are fixed, are called. For this reason, the primary winding is called the rotor. The primary winding in a synchro or a resolver can be physically rotated with respect to the secondary windings.
SYNCHRO RESOLVER WITH RESPECT TO API HOW TO
How to get Technical Assistance from a Technical Support Moderator.The impedance at 60Hz will be low enough that you burn it up! Lastly, never connect 60Hz power to a 400Hz device. It's quite possible that you have an older model that predates online documentation. Your best bet might be to call Kearfott directly and ask for information on your part. There are several similar part numbers that have a NSN (National Stock Number) which refer to a size 11, six or seven lead 400Hz resolver like you have. I looked over the resources I have at home and couldn't get any information on the Kearfott part number you listed. They are also available in 50Hz, 60Hz, 400Hz, and even kilohertz varieties. This model can be used as a true Synchro/Resolver standard for calibrating and testing Automatic Test Equipment (ATE) for Calibration/Metrology Labs, and for Engineering Design and Production Test environments.
SYNCHRO RESOLVER WITH RESPECT TO API SIMULATOR
NAI’s 5300 Synchro/Resolver Standard & Simulator is a laboratory-grade, programmable instrument. Since they aren't used to transmit torque they are generally run at lower voltage and power levels than a synchro. 5300 Programmable S/R Standard & Simulator. Resolvers are a close cousin of the synchro but instead of having a single 3 phase stator winding, they have two 2-phase windings 90 degrees apart so you end up getting a sine-cosine voltage relationship that relates back to the shaft angle. They are seldom used in the commercial world anymore however I deal with them on a practically daily basis in the defense world (I work for a Navy contractor). They come in both 50-60Hz and 400Hz varieties. One big advantage synchros have is you can connect two of them together lead-to-lead and when you turn one shaft the other will follow (they're synchronized hence the name synchro).
You can use these voltages in combination with their phase relative to the reference voltage to determine the absolute angle of the shaft. The S-leads are wound 120 degrees apart so as you turn the shaft of a synchro you get changing voltages between the S-leads. Typically 120VAC is connected to the R-leads which induces a voltage into the S-leads. Synchros have 5 connections: 2 reference leads and 3 stator leads. Synchros and resolvers are two different things.
