Slip ring motor connection:

This diagram shows how to make a Slip ring motor connection. In this circuit, we use an MCCB ( Molded Case Circuit Breaker ), a magnetic contactor, an overload relay, some other contactor, and a 3-phase motor. First, we need to connect the MCCB with the power source, then connect the contactor and overload then connect the 3-phase motor with the overload, and lastly connect all contactors with the motor. Now this circuit is ready for use.

Components used to make the Slip ring motor connection:

01. MCCB:

The MCCB consists of a bimetallic sheet that expands and contracts when the temperature of the MCCB changes. Due to overload, the bimetallic strip will start to bend and eventually, it will trip if more current flows in the circuit than the predetermined current. The trip mechanism opens the breaker. MCCB stands for Molded Case Circuit Breaker. It is another type of electrical protection device that is used when the load current exceeds the limit of a miniature circuit breaker. The MCCB provides Protection against Overload, and Short Circuit Faults and is also used for Switching the Circuits.

02. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

03. Overload Relay:

Overload Protection is Protection Against a Running Overcurrent That Would Cause Overheating of The Protected Equipment. Hence, An Overload is Also a Type of Overcurrent. Overload Protection Typically Operates on an Inverse Time curve where the Tripping Time Becomes less as the Current Increases. This Overload Protector is an Essential Component for Many Sockets. The Top-Quality Overload Protector can Effectively Protect Electrical Products from Power Surges.

04. 3 Phase Motor:

A Three-Phase electric motor uses a 3-Phase Power Supply to Convert Electric Energy into Mechanical Energy. It contains four Wires (Three hot Wires and one Neutral Wire) and Uses 3 Alternating Currents of the Same Frequency. Since it Generates a Rotating Magnetic Field, it does not need a Capacitor for the Startup. Some Three-Phase Motors are Reversible, Which Means they can serve as Generators by Turning Mechanical Energy into Electrical Energy.
