a series motor started without load can go into a condition called runaway. The motor will rapidly accelerate to unsafe speeds literally pulling itself apart. This condition should never be allowed to happen. Consult a professional when installing any electrical equipment.

What is starting torque?
The torque which is produced during the starting of motor is simply called as starting torque.
What property does not apply to a motor?
Which property does not apply to a motor?
How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
Why you use DOL starter in starting of motor?
because of starting current of induction motor is very high and it damages the insulation of motor
Why motor does not trips on instantaneous current during starting?
If the protection device is bimetalic type then it takes a few seconds to get heated up before tripping off. In case of other advanced type of protection devices, there could be a preset timer to allow a certain amount of high starting current. In both the cases, the avoidence of tripping during starting is by design, since it is known that the motor takes a high starting current.
Do commercial motor vehicle regulations apply to personal motor vehicles?
Absolutely not.
Where do you apply for a replacement license?
Department of Motor Vehicles or registry of motor vehicles
What is the best type of electric motor for heavy starting loads?
The classic heavy starting load is a tram starting off from stationary, and for this the series-would dc motor is the preferred motor.
Can you apply plugging in synchronous motor?
yes
Disadvantages of a squirrel cage motor?
Squirrel Cage Induction Motor Disadvantages:Some of disadvantages or demerits of squirrel cage induction motors are listed below:Main disadvantage of squirrel cage induction motor is that they have poor starting torque and high starting currents. Starting torque will be in the order of 1.5 to 2 times the full load torque and starting current is as high as 5 to 9 times the full load current. In slip ring induction motors, higher starting torque can be attained by providing an external resistance in the rotor circuits during starting of the slip-ring induction motor. This arrangement in slip-ring induction motors also reduces the high inrush currents during starting of induction motor.Squirrel cage induction motors are more sensitive to the supply voltage fluctuations. When the supply voltage is reduced, induction motor draws more current. During voltage surges, increase in voltage saturates themagnetic components of the squirrel cage induction motor.Speed control is not possible in squirrel cage induction motor. This is one of the major diadvantages of squirrel cage induction motors.The total energy loss during starting of squirrel cage motor is more compared to slip ring motors. This point is significant if the application involves frequent starting
How is the full load current different to the starting current- is the full load current higher or lower than the starting current?
While starting a motor from standstill to its rated speed, the motor has to overcome the inertia and generate enough torque to over come it. In the process the motor takes higher current during the starting. Once started and set in motion the current reduces ti its normal value. Full load current is lower than the starting current normally.
Which motor is used for starting engine?
Er... a Starter Motor?
