Question

Accepted Answer

There are several types of connections in motors, including star (Y) connection, delta (Δ) connection, and series connection.

Star (Y) connection: The three motor windings are connected in a Y shape, with one end of each winding connected to a common point.
Delta (Δ) connection: The three motor windings are connected in a triangle shape, with the end of each winding connected to the start of the next winding.
Series connection: The motor windings are connected in series, with the end of one winding connected to the start of the next winding.
Other types of connections include parallel connection and combination connections.
The type of connection used in a motor depends on factors such as the motor's design, power requirements, and intended application.
