whats inside an electric motor tester dynometer , CAN I BUILD ONE ??
hello guys
i basically understand the idea of a dynamo meter , input power and output power from an electrical motor to determine its characteristic curve . now i can measure input voltage and current , and output speed , but the problem is output torque ! how can i measure the output torque ( or braking torque ) without stopping the motor , and what type of brake is used to apply torque on the motor in actual dynamo meters .
i want to build one , since they are expensive , the motor size is 200w to 2000w
thanks for any help , if you think the post should be moved somewhere else please advise
