Maintenance Department Technician Interview Questions and Answers

Different types of machines are used to make gears. Flat belt and V-belt are types of belts used in machines. Leaf spring and sprocket are gear components.

• Gear cutting machines include hobbing machines, gear shapers, and gear grinders.

• Flat belts are thin and flat, while V-belts have a V-shaped cross-section.

• Leaf springs are used to provide suspension in vehicles and machinery.

• Sprockets are toothed wheels that mesh with a chain or belt to transmit power.

AC motors include induction motors and synchronous motors, while DC motors include brushed DC motors and brushless DC motors. AC starters include direct-on-line starters and star-delta starters, while DC starters include manual starters and magnetic starters.

• AC motors: induction motors, synchronous motors

• DC motors: brushed DC motors, brushless DC motors

• AC starters: direct-on-line starters, star-delta starters

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 electrical power transmission and distribution systems.

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

• Transformers are commonly used in power substations, electrical appliances, and electronic devices.

Voltage is the measure of electric potential difference between two points in an electrical circuit.

• Voltage is measured in volts (V)

• It is the force that drives electric current through a circuit

• Higher voltage means more energy is available to move electrons

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

• Examples of voltage sources include batteries, generators, and power outlets
