What Is a Dc Selsyn System?

DC Selsyn Systems
On aircraft with direct current (DC) electrical systems, the DC selsyn system is widely used. The selsyn system consists of a transmitter, an indicator, and connecting wires. The transmitter consists of a circular resistance winding and a rotatable contact arm.

What is a selsyn motor?

Summary: Selsyn (synchro) motors

A synchro, also known as a selsyn, is a rotary transformer used to transmit shaft torque. A TX, torque transmitter, accepts a torque input at its shaft for transmission on three-phase electrical outputs.

What power is required for a selsyn indicator system?

1. The system does not require an a-c source of power. 2. The system requires only three wires between transmitter and receiver, whereas all other types of systems require at least five wires leading from the transmitter to the receiver.
