Technologist Interview Questions and Answers

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors work on the principle of electromagnetic induction.

• They consist of a rotor, stator, and commutator.

• The rotor rotates due to the interaction between the magnetic field and the current flowing through the stator.

• Examples include electric motors used in household appliances and industrial machinery.

• Types of motors include AC motors, DC motors, and stepper motors.

The life cycle of a data science project involves several stages from problem definition to deployment.

• Problem definition and understanding

• Data collection and preparation

• Exploratory data analysis

• Model building and evaluation

• Deployment and monitoring
