A 3-phase motor is an electrical device that converts electrical energy into mechanical energy using three alternating currents.

• A 3-phase motor is more efficient and has higher power output compared to a single-phase motor.

• It is commonly used in industrial applications for driving heavy machinery and equipment.

• The motor consists of a stator and a rotor, with the stator providing a rotating magnetic field and the rotor ...read more

To maintain motors and electric equipment, regular cleaning, lubrication, and inspection are essential.

• Regularly clean motors and equipment to remove dust and debris.

• Inspect for any signs of wear, damage, or loose connections.

• Lubricate moving parts as per manufacturer's recommendations.

• Ensure proper ventilation and cooling for motors.

• Keep electrical equipment away from moisture and extreme temperatures.

Current is the flow of electric charge in a circuit.

• Current is measured in amperes (A).

• It is the rate at which electric charge flows through a conductor.

• Current can be either direct current (DC) or alternating current (AC).

• In a DC circuit, the current flows in one direction only.

• In an AC circuit, the current changes direction periodically.

• Current is caused by the movement of electrons or other charged particles.

• It is e...read more

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease the voltage in an electrical circuit.

• They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

• The primary winding is connected to the power source, while the secondary winding is con...read more

A capacitor is an electronic component that stores and releases electrical energy.

• A capacitor consists of two conductive plates separated by an insulating material called a dielectric.

• When a voltage is applied across the plates, one plate accumulates positive charge while the other accumulates negative charge.

• Capacitors are commonly used in electronic circuits for energy storage, filtering, timing, and coupling.

• They ca...read more

A fuse is a safety device that protects electrical circuits from excessive current flow.

• A fuse is a small, thin wire or strip of metal that melts when excessive current flows through it.

• When a fuse melts, it breaks the circuit and prevents further flow of current, protecting the electrical equipment.

• Fuses are commonly used in electrical systems to prevent damage from short circuits or overloads.

• They are rated for speci...read more
