Aimed at the problem of low efficiency for mini-car transmission system, the test bed for testing the efficiency of mini-ear transmission system was developed. Adopting direct current return flow test bed, the electric motor is used as power resource, the dynamometer controls the frequency changer through the direct torque, VC＋＋ software is used as the development tool to can＇y out the modularization. The efficiency of transmission system anti its components is tested in the test bed which provid...
