Swinburne's Test of DC Machine Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12961
Indian Lab Suppliers supplies the Swinburne's Test of DC Machine (Product ID: 12961) as part of its electronics engineering lab equipment range. It is a 0.5 HP DC shunt machine with a metering panel for finding its losses and predicting efficiency by Swinburne’s test.
Quick Answer
In Swinburne’s test the shunt machine runs as a motor at rated voltage and speed with no load; the input power minus the armature copper loss gives the constant (iron, friction and windage) losses, and the efficiency at any load is then calculated without loading the machine. The motor is rated 0.5 HP, 180/220 V, 1500 rpm, with armature and field terminals brought out and rheostat and starter terminals on the panel. A cast aluminium brake drum is also fitted, so a direct load test can be run to check the predicted figures. The test suits shunt and compound machines, not series machines.

Where This Is Used
Used in DC machines laboratories for loss separation and efficiency prediction. The shaft turns at 1500 rpm on a 200 V DC supply and the brake drum heats up, so guard the shaft and let the drum cool before handling.

Frequently Asked Questions
Does the machine need to be loaded for Swinburne’s test?
No, it is a no-load test; efficiency at other loads is calculated.
Can it be used for a DC series motor?
No, a series motor cannot be run at no load; use a field test instead.
What is the machine rating?
0.5 HP DC shunt, 180/220 V, 1500 rpm.
