Why is Dc shunt motor is not used to start at heavy load?
A DC shunt motor is not used to start under heavy load because it has a relatively low starting torque. At startup, the armature is stationary, leading to minimal back EMF and high armature current, which can cause excessive heating and potential damage to the windings. Additionally, the field current is constant, which does not provide the necessary torque boost needed for heavy loads. Consequently, other motor types, like series motors, are preferred for heavy load applications at startup.
Which motor is used in electric train and traction?
An electric train uses electric motors. Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
Why does an old electric motor start turning in the opposite direction?
It sounds like the starting capacitor is about to give up.
What is a machine that turns mechanical energy into electrical energy?
Electric motor.
The speed of an electric motor can be controlled by?
By using the star- delta starting methodBy using variable rhoestatsBy using auto transformers
Advantages of dc series motor?
It develops a large torque and can be operated at low speed. It is a motor that is well suited for starting heavy loads..
Why shunt motor not starting on heavy loads?
because it dont want to so go on google uu dumb retard
What is an example of a tractor?
a motor vehiclen used for pulling heavy loads.
How do electric chain hoists work?
Electric chain hoists use an electric motor to power a chain mechanism that lifts and lowers heavy loads. When the motor is activated, it drives the chain to lift the load, and when the motor is reversed, the load is lowered. These hoists are commonly used in industrial settings for their efficiency and precision in handling heavy materials.
What device transforms electrical energy into mechanical energy?
An electric motor, such as a starting motor
What devices transformer electrical energy into mechanical energy?
An electric motor, such as a starting motor
What does a Electric pallet jack receives its pressure from?
An electric pallet jack receives its pressure from hydraulic systems that are powered by an electric motor. The motor drives a hydraulic pump, which generates the necessary pressure to lift and lower the forks. This allows the pallet jack to maneuver heavy loads efficiently without requiring manual effort. The hydraulic system is typically controlled by a user-friendly interface, enabling precise handling of the load.
Why using on motor star delta starter?
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!

What is Advantages of using a series DC motor?
The DC series motor is a high torque motor. so that it can pull heavy loads such as traction, lifts etc., the control of speed of a DC series motor is very smooth and easy.
Which motor is used in electric train and traction?
An electric train uses electric motors. Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
What is the function of an electric motor in terms of electric power and motor?
The electric motor changes electric energy into mechanical energy.
