How can Swinburne's test be adopted for series motor?
the method can not be used in the case of a d.c series motor
Why is Swinburne's test done on dc machines?
because we cannot apply to series motor
What will happen to the transformer if double the rated voltage is applied to the winding during the open circuit test?
no voltage will be induced on the secondary side of the motor as the windings will become saturated.
What is electrical motor type test?
test in lamp
Need of load test of squirrel cage induction motor?
usually you just need to read the name plate only the manufacturer needs to test to come up with numbers on the nameplate most common load for testing motors is a water brake dynamometer

the method can not be used in the case of a d.c series motor

What is theory of brake test on dc shunt motor?
Brake test is used to determine the efficiency of comparatively small motors. The motor is loaded directly by means of a mechanical brake (load) or by means of an eddy current or a calibrated air fan.
Why is Swinburne's test done on dc machines?
because we cannot apply to series motor
Is Swinburne test applicable for dc series machine?
No.it is not applicable for dc series motor at no load..at no load armature current is too small in dc series motor and we know that speed is inversly proportional to the armature current(speed=v/kI-Ir/k).Hence speed is dangerously high which is not efficient for Swimburne's test...
Theory for brake test on three phase induction motor?
why three phase induction motor is delta connected
How do you test a slack adjuster?
Assuming we are talking about "S" cam air brakes on a truck, check the angle at the end of the slack adjuster to the actuator rod coming out of the air brake can when brakes are applied, it should be 90 degrees, if the slack adjuster is manual adjust it with the brakes not applied and then test again. If they are automatic slack adjusters and you do not have 90 degrees with brakes applied it is worn out or not installed correctly.
What does wattmetre indicates in brake test?
A watt-meter brake test means the produced in a cylinder. This is the measure torque during the test.
What is the break drum radius for a single phase induction motor?
The correct spelling is 'brake' rather than 'break', but the 'drum' you refer to is used when testing the output power at the shaft of an induction motor. The diameter will depend on the power of the motor, and the test equipment used. 'Brake power' refers to the output power of the machine measured in watts or, in the United States, in horsepower. If you know the output power (by conducting this test) and the input power (using a wattmeter), then you can determine the machine's efficiency.
What will happen to the transformer if double the rated voltage is applied to the winding during the open circuit test?
no voltage will be induced on the secondary side of the motor as the windings will become saturated.
What are symptoms of a bad power brake booster?
hard brake pedal is the most obvious sign only way i know to test a booster, is to turn engine off. use brakes several times till pedal is hard. then with brake applied,start engine. the brake pedal should then soften.if the pedal stays hard the booster is bad
What is break test on dc machines?
I think you probably mean a 'brake' test, not a 'break' test. A 'brake test' is performed to find the output power of any machine. In North America, this is commonly expressed as 'brake horsepower'; elsewhere it is expressed in 'watts'.
