Why should a series motor always start with a load?
Why should a shunt motor always start without a load?
Why should a shunt motor always start without a load?
A series motor is a type of electric motor where the field winding is connected in series with the armature winding. This means that the current flows through both the field and armature windings in a series, hence the name.
A series motor should always start with a load because it has a high starting torque and low starting current. This means that it is better equipped to handle the initial resistance of a load and can start smoothly without causing damage to the motor.
If a series motor starts without a load, it can experience a phenomenon called "overspeeding". This is when the motor runs at a higher than normal speed and can cause damage to the motor or connected equipment.
Yes, a series motor can be used for variable speed applications by using a variable resistance in the circuit. This allows for control of the motor's speed and torque. However, this method is not as efficient as using other types of motors designed specifically for variable speed applications.
Series motors are commonly used in applications where high starting torque is necessary, such as in electric trains, elevators, and hoists. They are also used in portable power tools and household appliances like mixers and blenders.
