Zen Technologies Design Engineer Interview Questions and Answers

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

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

• The machines can handle a wide range of component sizes and shapes, from tiny surface-mount resistors to large connectors.

• Some pick ...read more

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
