Question

01: Discuss the principle of operation of the (Synchro) and the (Resolver) machines, then choose and explain one application composes both machines simultaneously. (Draw the required diagrams).

Expert Solution
Step 1

The synchro and the resolver is electrically similar to the transformer and mechanically similar to the motor. The primary winding of the synchro and resolver can be physically rotated with respect to the secondary winding. Synchros and resolvers can be operated at various voltages and frequencies, up to the input current.

Step 2

The synchros and resolvers is used to perform as part of electro-mechanical servo and shaft angle positioning systems. The synchro performs as an electromechanical transducer. As a circuit element it requires to perform as a variable coupling transformer. The magnitude of the magnetic coupling between the primary and secondary varies according to the position of the rotating element. This in turn varies the magnitude of the output voltage. In some systems, a mechanical input, such as a shaft rotation, is converted to a unique set of output voltages. In others, a set of input voltages is used to turn a synchro rotor to a desired position.

Step 3

The design of the synchros and resolvers to operate with input voltages from 0.5 to 115 Vrms over a wide range of frequencies from 60 Hz to 100 kHz.. Depending on the size of the synchro or resolver, the input voltage and frequency may have to be limited. This limitation prevent the excessive input current to saturate the iron core.

While considering the construction aspect of the synchro has one primary winding and three secondary windings, with each secondary winding mechanically displaced at 120º apart. While a resolver has two primary windings and two secondary windings oriented at 90º to each other.
