空载

The motor's dynamic model, which is generally employed for speed control and parameter estimation applications, is improved for the purpose of improving the parameter estimation accuracy by the assumption that the stator self inductance Ls is identical to the rotor self inductance Lr. The motor's dynamic response to a direct on line start is used to estimate the parameters.

Methods 2.1 The experiment about changing electricic pressure values into the pulse-taking pressure values of making pressure standars of sphygmograph. Putting 1g、2g、5g、10g、20g、50g、100g、140g weights on the black1 probe and the black2 probe of NX-3 multifunctional sphygmograph ,putting 1g、2g、5g、10g、20g、50g weights on the purple probe of NX-3 multifunctional sphygmograph. Then we noted the the different pressure numerical value when putting none and different weights on the probes to prove the liner relationship between them. 2.2 Setting up wiry pulse model in achy rabbits We operated on the non-drugged state rabbits, exposure the carotid.
