Schindler Customer Engineer Interview Questions, Process, and Tips

An elevator works by using a system of pulleys, counterweights, and a motor to move the elevator car up and down within a shaft.

• Elevators have a motor that drives a pulley system to move the elevator car.

• Counterweights are used to balance the weight of the elevator car and reduce the load on the motor.

• Safety mechanisms such as brakes and sensors are in place to ensure safe operation.

• Elevators are controlled by buttons ...read more

An electrical motor is a device that converts electrical energy into mechanical energy.

• Uses electromagnetic fields to generate motion

• Common types include DC motors and AC motors

• Can be classified based on construction (e.g. brushed, brushless) or application (e.g. servo, stepper)

• Examples: induction motor, synchronous motor, brushed DC motor, brushless DC motor

I have worked with various types of motors including AC motors, DC motors, stepper motors, and servo motors.

• AC motors: Used in household appliances and industrial applications.

• DC motors: Commonly found in electric vehicles and robotics.

• Stepper motors: Used in precision positioning systems and 3D printers.

• Servo motors: Found in robotics and automation for precise control.

MCB stands for Miniature Circuit Breaker.

• MCB is an electrical switch that automatically interrupts the flow of current in an electrical circuit during an overload or short circuit.

• It is a type of circuit breaker that is commonly used in residential and commercial buildings to protect electrical circuits from damage.

• MCBs are designed to trip and disconnect the circuit when excessive current flows through it, preventing ...read more

A bridge rectifier is an electronic circuit that converts alternating current (AC) to direct current (DC).

• A bridge rectifier consists of four diodes arranged in a bridge configuration.

• It rectifies the AC input voltage by allowing current to flow in only one direction.

• During the positive half-cycle of the AC input, two diodes conduct and during the negative half-cycle, the other two diodes conduct.

• This results in a puls...read more

A PNP transistor symbol consists of an arrow pointing inward, while an NPN transistor symbol consists of an arrow pointing outward.

• PNP transistor symbol has an arrow pointing inward

• NPN transistor symbol has an arrow pointing outward

The operation of a solenoid coil involves the conversion of electrical energy into mechanical motion.

• A solenoid coil consists of a wire wound into a tightly packed helix.

• When an electric current passes through the coil, a magnetic field is generated.

• This magnetic field attracts or repels a movable ferromagnetic core, resulting in mechanical motion.

• The direction of the motion depends on the polarity of the current and t...read more

VFD's (Variable Frequency Drives) are electronic devices used to control the speed and torque of electric motors.

• VFD's convert fixed frequency AC power to variable frequency power, allowing precise control of motor speed.

• They are commonly used in industrial applications to save energy, improve motor performance, and reduce wear and tear.

• VFD's consist of three main components: rectifier, DC bus, and inverter.

• The rectifi...read more

• Identify possible causes and narrow down the root cause

• Develop a plan to address the issue step by step

• Test solutions and verify if the issue is resolved

• Document the troubleshooting process for future reference

AC and DC are types of electrical current.

• AC stands for alternating current and changes direction periodically.

• DC stands for direct current and flows in one direction only.

• AC is used in household appliances and power grids while DC is used in batteries and electronic devices.

• AC voltage can be easily transformed using a transformer while DC voltage cannot be transformed without a converter.
