What else can I help you with?
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.
What is the difference between traction motor and general motor?
A series motor is employed for traction application which has starting torque and permits intermittent operations by braking, which cannot be expected of a general purpose motor.
Why series motor used in traction application?
becoz of high starting torqe to move train
Why ac motors are not used in railways?
Ac motor has a low starting torque so that DC series motor used in railways cause DC motor has high starting torque
How many times greater is the starting torque than the normal full-load torque for split phase motor?
4 times
What kind of motor uses a differential reluctance pole to produce starting torque?
shaded pole
Why you use delta star combination in transmission line from generating station to feeder station?
The starting current is about 30 % of the direct-on-line starting device. The starting torque is about 25 % of the direct-on-line starting torque. The stress on an application is reduced compared to the direct-on-line starting method.
What is starting torque?
The torque which is produced during the starting of motor is simply called as starting torque.
Where theSlip ring induction motors are used?
The slip ring induction motors are usually used in the application requiring the low starting current or the high starting torque.
Is DOL starter is sufficient for 10HP 2880 RPM motor?
If the application is high starting torque, then go for star delta or soft starters. If not DOL will do.
What is the best Torque converter for a Chevy 350?
The best torque converter is one that is custom built to suit the intended application.
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.
What is the difference between traction motor and general motor?
A series motor is employed for traction application which has starting torque and permits intermittent operations by braking, which cannot be expected of a general purpose motor.
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.
What is the relationship between torque and acceleration in the context of the formula for rotational motion?
In the context of rotational motion, torque is directly proportional to acceleration. This means that increasing torque will result in a greater acceleration, and decreasing torque will result in a lower acceleration. The relationship between torque and acceleration is described by the formula: Torque Moment of Inertia x Angular Acceleration.
Why series motor used in traction application?
becoz of high starting torqe to move train
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
