The numerical we are going to solve in this video are as mentioned below
The following test results were obtained while performing the break test on a d.c. shunt motor.
Spring balance reading : Tight side - 30.5 kg
: Slack side - 5.6 kg
Effective diameter of the break drum D = 0.3m
Speed of the motor N = 960 rpm
Supply voltage V = 230 V
Input line current Il = 18 A
Find the output horsepower and efficiency of motor.
The following test results were obtained while performing break test on a 250 V d.c. shunt motor.
Reading of the spring balance on the tight side = 38.0 kg
Reading of the spring balance reading on the slack side = 11.1 kg
Diameter of the break drum = 700mm
Thickness of the belt = 10 mm
Speed of motor = 750 rpm
Armature current = 30A
Field current = 2.7 A
Find the output horsepower of the motor and efficiency.
You need to solve this example.
The following test results were obtained while performing break test on a 220 V d.c. shunt motor.
Reading of the spring balance on the tight side = 40.0 kg
Reading of the spring balance reading on the slack side = 12 kg
Diameter of the break drum = 800mm
Thickness of the belt = 15 mm
Speed of motor = 800 rpm
Armature current = 25A
Field current = 2.2 A
Find the output horsepower of the motor and efficiency.
