10+ Jost's Engineering Interview Questions and Answers

When the limit switch brakes but you have to run, it can lead to potential damage or malfunction.

• Running the system without the limit switch can result in overloading or exceeding safe operating limits.

• It may cause damage to the equipment or components due to excessive force or movement.

• Without the limit switch, there is a risk of the system operating outside its intended range, leading to safety hazards.

• Continuing to run without the limit switch can void warranties or insura...read more

Possible problems when hydraulic doesn't sustain load

• Insufficient hydraulic fluid

• Leakage in the hydraulic system

• Faulty hydraulic pump

• Clogged or damaged hydraulic lines

• Malfunctioning control valves

• Worn-out or damaged hydraulic cylinder seals

Types of motors and their differences

• There are various types of motors such as DC motors, AC motors, stepper motors, and servo motors.

• DC motors operate on direct current and are commonly used in applications like electric vehicles and robotics.

• AC motors operate on alternating current and are widely used in household appliances and industrial machinery.

• Stepper motors move in discrete steps and are commonly used in printers, CNC machines, and robotics.

• Servo motors are controlle...read more

A hydraulic system is a technology that uses pressurized fluid to transmit power and control movement. Gears are mechanical components that transmit torque and rotation between shafts.

• Hydraulic systems use a pump to pressurize fluid, which is then used to power cylinders, motors, and other components.

• Gears come in many shapes and sizes, including spur, helical, bevel, and worm gears.

• Gears are used in many machines, including cars, bicycles, and industrial equipment.

• Hydraulic ...read more

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 and a stator

• Common types include DC motors, AC motors, and stepper motors

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

The pick current of a motor refers to the maximum current that the motor can draw under normal operating conditions.

• Pick current is important for determining the appropriate size of protective devices such as fuses and circuit breakers.

• It is also crucial for selecting the right motor starter and ensuring the motor operates safely.

• For example, a motor with a pick current of 10A would require a fuse or circuit breaker rated higher than 10A to prevent overload.

• Calculating pick c...read more

The starting current of a driver motor is typically higher than the rated current due to the initial surge of power needed to start the motor.

• Starting current is usually 5-7 times higher than the rated current of the motor.

• This high starting current is needed to overcome the inertia of the motor and bring it up to speed.

• Once the motor is running, the current will decrease to the rated value.

• Using soft starters or variable frequency drives can help reduce the starting current ...read more

DC motors work by using direct current to create a magnetic field that interacts with the motor's coils to produce rotational motion.

• DC motors use direct current to create a magnetic field within the motor.

• The magnetic field interacts with the motor's coils, causing them to rotate and produce motion.

• The direction of rotation can be controlled by reversing the polarity of the current.

• DC motors are commonly used in appliances, vehicles, and industrial machinery.

Linear speed of a conveyor can be calculated by dividing the distance traveled by the time taken.

• Calculate the distance traveled by the conveyor belt in a certain time period

• Determine the time taken for the conveyor belt to travel that distance

• Divide the distance by the time taken to get the linear speed

A motor works by converting electrical energy into mechanical energy to produce motion.

• Motors have coils of wire that create a magnetic field when electricity passes through them.

• The magnetic field interacts with permanent magnets to create a force that rotates the motor's shaft.

• Different types of motors include DC motors, AC motors, and stepper motors.

• Examples of motors include electric fans, washing machines, and electric vehicles.

Starting current of a motor refers to the current drawn by the motor when it is initially started.

• Starting current is typically higher than the rated current of the motor.

• It is important to consider the starting current when sizing protective devices like fuses and circuit breakers.

• Soft starters and variable frequency drives can be used to reduce the starting current of a motor.

• Example: A motor with a rated current of 10A may have a starting current of 6-8 times the rated cur...read more
