What happens to a shunt motor when the starting torque required is too high at start-up?
If the starting torque required is too high for a shunt motor, it could lead to stalling or jerky operation at startup. This can cause overheating and damage to the motor windings due to increased current draw. It is important to match the motor's torque capabilities with the load requirements to prevent these issues.

How does friction affect the amount of torque required to move an object?
Friction increases the amount of torque required to move an object. This is because friction creates resistance between the object and the surface it is moving on, making it harder to overcome and requiring more torque to initiate and maintain movement.
What are some common torque questions that are frequently asked in mechanical engineering interviews?
Some common torque questions asked in mechanical engineering interviews include: What is torque and how is it calculated? How does torque affect the performance of a machine or system? Can you explain the difference between static and dynamic torque? How do you determine the torque required to move a specific load? What factors can affect the torque output of a motor or engine? How do you calculate the torque required for a specific application or task? Can you discuss the importance of torque in mechanical design and analysis? How do you measure and test torque in a mechanical system? Can you explain the concept of torque multiplication and its applications? How do you troubleshoot and resolve torque-related issues in a mechanical system?
What are different types of torque?

Find the torque required to tighten a 10mm nut if the force on the end of the spanner is 10kg and the length of the spanner is 95mm?
The torque required can be calculated as the force applied multiplied by the distance from the center (lever arm). Convert the force from kg to Newtons (10kg = 98.1N) and the length from millimeters to meters (95mm = 0.095m). The torque required is 9.33 N*m (98.1N * 0.095m).
What is the change over time from star to dealta in the start up of an electrical motoR?
The change from star to delta in the startup of an electrical motor involves switching the motor windings from a configuration where they are connected in a star pattern to a configuration where they are connected in a delta pattern. This change helps the motor to transition from starting with reduced current and higher torque (star) to operating at full speed and power (delta). It is a common method used to control the motor's performance characteristics during startup.
What difference between running torque and starting torque?
Torque is the the force required to move a body about its fulcrum. The starting Torque is the force required to move the body from 0 rpm to the stipulated rpm, the Running torque is the force required to maintain the rpm. The Starting torque is often higher than the running force. Imagine peddling a push bike with one gear (say the one gear is a high gear), the force required to set off will be relatively high in comparison to the force you exert in order to maintain a velocity.
What is starting torque?
The torque which is produced during the starting of motor is simply called as starting torque.
How floating condition of synchronous motor occurs?
at the time of starting when syncchronous torque is zero , i.e. when the motor starts with the help of starting torque , the armature current required to produce sync. torque is zero. If V = E(b) i.e. When back emf E(b) equals supply voltage.
Why high starting torque is required for trains?
because train has heavy mass & due to heavy mass inertia is also very high so more effort is required getting motion in train. it is also known that any type of motor required more initial torque for come in speed.
How do you set tappets of 4.0L Jeep Cherokee?
No adjustment required. Just torque the rockers down.No adjustment required. Just torque the rockers down.
How much Torque is required to start the motor?
The torque required to start a motor depends on several factors, including the motor type, its size, load conditions, and friction in the system. Generally, the starting torque must overcome the static friction and inertia of the rotor and any connected load. For precise calculations, one would typically refer to the motor's specifications or perform a detailed analysis of the system's dynamics. If you have specific motor parameters, I can help estimate the required torque.
What is breakaway torque?
Breakaway torque is the amount of torque required to overcome the static friction of a stationary object and set it in motion. It is a measure of the minimum force or torque needed to break something free from its initial position.
Why field rheostat of dc shunt motor kept in minimum position?
it is kept at minimum position to produce more torque which is required for starting a motor
Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
Why the starting torque of a dc series motor is high?
load is heavier so starting torque is requiredAnswerBecause the same current is passing through both the armature and field windings, the torque is proportional to the squareof the current. Since the starting current is alway high (no back emf), the torque will be very high indeed.
Why the pull up torque is less than starting torque?
at starting or initial stage there is no acceleration,it requires more force or power to move any body during initial stage,where as in running condition,it also requires some force or power whioch is less then the imitial power.hence the starting torque is always > pull up torque
