Hopkinson's Test is another useful method of testing the efficiency of a Efficiency for a BLDC motor of up to 96.5% have been reported, whereas DC motors with brushgear are typically 75–80% efficient.
What is the purpose of Hopkinson test?
Definition: A full load test which is used to test the efficiency of a DC machine is known as Hopkinson's test. An alternate name of this test is back to back, heat run, and regenerative test. This test uses two machines which are connected electrically and mechanically with each other.
How does Hopkinson test is done?
Hopkinson's Test is also known as Regenerative Test, Back to Back and Heat Run Test. In Hopkinson Test, two identical shunt machines are required which are coupled both mechanically and electrically in parallel. One is acting as a motor and another one as a generator.
