Merlinhawk Aerospace Design Engineer Interview Questions and Answers

Q1. All things about the servo motors
Add your answer
Q2. How servo motor works
Ans. 
A servo motor is a rotary actuator that allows for precise control of angular position, velocity, and acceleration.
• Servo motors use feedback control to maintain a desired position or speed

• They typically have a DC motor, a gearbox, and a control circuit

• The control circuit sends a signal to the motor to adjust its position based on feedback from a sensor

• They are commonly used in robotics, CNC machines, and automation sys

Q3. How to do DFMEA for the motor in production
Ans. 
DFMEA for motor in production involves identifying potential failure modes and their effects on the system.
• Identify all potential failure modes of the motor

• Determine the severity of each failure mode

• Assess the likelihood of each failure mode occurring

• Evaluate the detectability of each failure mode

• Develop actions to mitigate or eliminate high-risk failure modes

• Continuously monitor and update the DFMEA throughout product...read more

Q8. What is LVDT have you used it before
Ans. 
LVDT is a type of sensor used to measure linear displacement.
• LVDT stands for Linear Variable Differential Transformer.

• It consists of a primary coil, secondary coils, and a movable core.

• As the core moves, it induces a voltage in the secondary coils which is proportional to the displacement.

• LVDTs are commonly used in industrial and automotive applications for position sensing and control.

• I have used LVDTs in a previous p...read more
