Oben Electric Vehicle Interview Questions, Process, and Tips

The least count of a Vernier caliper is the smallest measurement that can be read on the scale.

• The least count is typically 0.02 mm or 0.001 inches on a Vernier caliper.

• It is determined by the number of divisions on the main scale and the Vernier scale.

• For example, if the main scale has 20 divisions and the Vernier scale has 19 divisions, the least count would be 0.05 mm.

Drum brakes use brake shoes that press outwards against a rotating drum, while disc brakes use brake pads that squeeze against a rotating disc.

• Drum brakes are typically found on older vehicles, while disc brakes are more common on modern vehicles.

• Disc brakes provide better stopping power and are more efficient at dissipating heat compared to drum brakes.

• Drum brakes are usually located inside the wheel hub, while disc b...read more

Motors are devices that convert electrical energy into mechanical energy to produce motion.

• Motors can be categorized into different types such as AC motors and DC motors.

• Motors are commonly used in various applications such as industrial machinery, household appliances, and vehicles.

• Examples of motors include electric motors in fans, pumps, and electric vehicles.

DC motors use direct current to power the motor, while AC motors use alternating current.

• DC motors have a constant magnetic field, while AC motors have a changing magnetic field.

• DC motors are simpler in construction compared to AC motors.

• DC motors are commonly used in applications where speed control is important, such as in electric vehicles.

• AC motors are more commonly used in household appliances and industrial appli...read more

Motor winding is the process of creating electromagnetic coils in the stator or rotor of an electric motor.

There are various types of motors used in different applications, such as AC motors, DC motors, stepper motors, and servo motors.

• AC motors: commonly used in household appliances and industrial applications

• DC motors: used in toys, electric vehicles, and small household appliances

• Stepper motors: used in robotics, 3D printers, and CNC machines

• Servo motors: used in automation, robotics, and precision control systems

AC motors use alternating current while DC motors use direct current.

• AC motors use a changing electrical current to produce rotational motion

• DC motors use a constant electrical current to produce rotational motion

• AC motors are typically used in household appliances and industrial machinery

• DC motors are commonly found in battery-operated devices like toys and tools

Winding of the motor is the process of wrapping wire around a core to create an electromagnetic field.

• Winding determines the speed, torque, and efficiency of the motor.

• There are different types of windings such as lap winding and wave winding.

• The number of turns and gauge of wire used in winding affects the motor's performance.
