Heavy truck cab manual oil pump consumes more time and strength. Using tilting motor can produce larger tilting force for reversing the heavy truck cab and improve the tilting efficiency. The power of tilting motor, permanent magnet, armature plate and winding parameters are optimized on the basis of analyzing the cab tilting system works and the characteristics of the permanent magnet DC motor. The designed Nb-Fe-B PM DC motor is small volume, light weight high efficiency, simple structure and reliable operation characteristics, which can improve the security of tilting device of the heavy truck cab.
In this paper we are studying about maximum R.P.M. of Permanent Magnet DC Motor. In this way we are using the regulator circuit and 1Amp. 2 Amp. 3Amp. With different voltages. R.P.M. of D.C. motor is measured by the digital type tachometer. The D.C. power supplies are obtaining by the rectifier circuit and also used the step down transformer.
